Highly Beneficial Native Chara vulgaris Plays a Critical Role in Promoting and Sustaining Healthy Aquatic Ecosystems and Bio-Diversity in Many of Michigan’s Inland Lakes

by Scott Brown
MWA Director
e-Newsletter Editor

Members of the the diverse Characeae family that currently exist within thousands of inland lakes located in the Laurentian Great Lakes region include highly beneficial native species such as Chara vulgaris and Chara braunii as well as the highly invasive exotic species Nitellopsis obtusa (see the photo that appears belowthat is commonly referred to as starry stonewort. It is important to recognize that abundantly growing Chara vulgaris, the most frequently observed and abundant Characeae species within the Great Lakes region, makes important contributions to achieving and sustaining sunlight drenched waters, and healthy, aesthetically pleasing clear water inland lakes that serve to provide an array of valuable recreational opportunities.

Bottom hugging dense Chara vulgaris meadows that are often observed growing in shallow, near shore areas of moderately productive lakes are known to play a particularly important role in contributing to good water clarity by helping to prevent the resuspension of fine organic particulate matter; by helping to promote and sustain a diverse and beneficial array of water clarity, sunlight dependent native submerged aquatic plants; by utilizing and/or storing nutrients that would otherwise be available to support the growth of water clarity degrading phytoplankton; by serving as vital protective habitat for juvenile fish seeking to avoid predation; and by releasing allelopathic chemicals that act to inhibit water clarity degrading algae.

The existence of clear water dependent Characeae species such as native Chara brauniiChara vulgaris, and exotic invasive starry stonewort within the northern temperate inland lakes of the Laurentian Great Lakes region are considered reliable bio-indicators of the existence of relatively clear, sunlight inundated waters, and optimal physical habitat conditions.

A Letter from MWA and Lake Appreciation Day Partners to the MI State Senate and House of Representatives

To: Members of the Michigan Senate and House of Representatives

From: Michigan Waterfront Alliance and Lake Awareness Day Partners 

RE: Donation Option on Watercraft Registrations 

Due to the ever-increasing ecological threat and economic disruption that Aquatic Invasive Species are having on our Michigan inland waterways, Michigan Waterfront Alliance and our Lake Awareness Day Partners Propose the following:

1. Fund Aquatic Invasive Species (AIS) Prevention and Control on Michigan’s inland waterways with a Donation Option on Watercraft Registrations. No specific donation amount would be suggested, and each volunteer donor would receive a decal acknowledging their donation along with their watercraft registration decal.

2. The MI Department of Environment, Great Lakes, and Energy (EGLE) would create an AIS Prevention and Control Fund Advisory Committee modeled after the office that is responsible for dispersing funds generated by the “Protecting Our Waters” specialty license plate program. This AIS Prevention and Control Fund Advisory Committee would be responsible for making decisions regarding the allocation and dispersal of funds generated by the watercraft registration donation option program.

3. We must ensure the existence of language within the proposed legislation that will serve to ensure that the revenue generated by the Watercraft Registration Donation Option program is “protected” and therefore “restricted” for use only to fund Aquatic Invasive Species Prevention and Control program related functions and activities.

Legislation Draft of:

Fund AIS Prevention and Remediation on Michigan’s inland waterways with a Donation Option on Watercraft Registrations. Funds collected by the Watercraft Registration Donation Option program for AIS Prevention and Control on Michigan’s public waterways by the Michigan Secretary of State will go directly to the state treasurer who shall credit donated funds to an account(s) established by the AIS Prevention and Control Fund Advisory Committee.

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) shall establish an AIS Prevention and Control Fund Advisory Committee whose primary responsibility will be to advise EGLE on the watercraft registration Donor Option program. The Donor Option program shall be primarily dedicated to providing grants to local units of government, inland lake, river, and stream associations and other non-governmental organizations for the sole purpose of Aquatic Invasive Species Prevention and Control. The Department of Environment, Great Lakes, and Energy may promulgate rules to implement this grant program under the auspices of the Administrative Procedures Act of 1969, 1969 PA 306, MCL 24.201 to 24.328.

  1. The AIS Prevention and Control Fund is created within the Michigan state treasury. The state treasurer may receive money or other assets from any source for deposit into the fund. The state treasurer shall direct the investment of the fund. The state treasurer shall credit to the fund interest and earnings from fund investments. Money in the fund at the close of the fiscal year shall remain in the fund and shall not lapse into the general fund. Money from the fund shall be expended, upon appropriation, solely for the purpose of AIS Prevention and Control on Michigan’s waterway.
  2. For the purpose of this chapter, “local units of government” shall be defined as any of the following:
  • A county, city, village or township
  • An agency of a county, city, village or township
  • The office of a county drain commissioner
  • A soil conservation district established under Part 93 of the Natural Resources and Environmental Protection Act of 1994, PA 451 – MCL 324.9301 to 324.9313.
  • A watershed council established under Part 311 of the Natural Resources and Environmental Protection Act of 1994, PA 451 – MCL 324.31101 to 324.31119.
  • A local health department as that term is defined in Section 1105 of Public Health Code, 1978, PA368 – MCL 333.1105.
  • A community college or junior college established pursuant to Section 7 of Article VIII of the state constitution of 1963.
  • A 4-year institution of higher education, public or private, located within the State of Michigan.

3.For purposes of this chapter, “lake, river, or stream association” shall be defined according the

following criteria:

Any State of Michigan currently incorporated inland lake, river or stream organization.

4.For the purpose of this chapter, “non-government organization” shall be defined by the

Michigan Department of Environment (EGLE).

Grand Traverse County Enacts a Modest Septic System Ordinance

by Scott Brown

MWA e-Newsletter Editor

Responding to the sad fact that Michigan remains the only state within the United States of America that has not yet enacted a common sense statewide septic system code, the Grand Traverse County Board of Commissioners recently voted to help protect public health and extraordinarily valuable freshwater ecosystems by unanimously passing a countywide septic ordinance. Defined by 132 miles of Great Lakes coastal shoreline, 146 named inland lakes, many more unnamed lakes, and two major rivers, a recently published story regarding the rare action by For Love of Water Advocates aptly describes passage of the ordinance as Grant Traverse County “positioning itself as a leader in safeguarding public health and freshwater resources in the absence of a statewide septic code.”

The recently enacted Grant Traverse County ordinance indicates that beginning on January 1, 2026, any property with a septic system that is located within 300 feet of any above-ground body of freshwater such as lakes, ponds, streams, or rivers–must be evaluated before it can be sold or transferred. Passage of the ordinance came in response to the fact that Grand Traverse County commissioners as well as officials from the county health department recognized that a properly functioning septic system is essential to preventing pathogens as well as harmful nutrients and chemical pollution from entering freshwater ecosystems and groundwater aquifers.

The action taken by Grand Traverse County to help protect human health and economically valuable freshwater ecosystems is particularly noteworthy due to the fact that only 13% of counties in Michigan have enacted local regulations that require septic systems to be evaluated. It is also important to note that hundreds of thousands of failing septic systems in Michigan continue to be a major source of e-coli and human fecal bacteria laden raw sewage that contaminates our ground water, and renders the waters of many our lakes, rivers, and streams unfit for total contact water sports such as swimming or snorkeling.

The steadily escalating environmental and public health associated problem in Michigan is derived from that fact that approximately 20%, or 280,000, of the 1.4 million septic systems that were constructed during the residential building boom of the 1950’s and 1960’s throughout Michigan are now failing. The overall significance of on-going problem has also been exacerbated by the fact that many Michigan homes and their now severely antiquated and often dysfunctional septic systems were built prior to the construction of sewer systems that now serve even the smallest of towns and villages.

Septic systems, otherwise known as on-site waste water disposal systems, are designed and installed in order to manage and treat the waste generated by toilets before it reaches ground water. In a properly designed septic system, the septic tank serves to remove larger solids from wastewater. Wastewater that flows out of the septic tank is saturated with contaminants that must be removed before the water can safely be combined with surface and/or groundwater. Public health issues stem from the fact that septic tank effluent contains large concentrations of toxic micro-organisms that are capable of making people sick. Moreover, the organic matter present in wastewater effluent creates bad odors, and contains algae growth stimulating nutrients (nitrogen and phosphorus) that can have a negative impact on the aquatic ecosystems of our inland lakes, rivers, and streams. Properly designed septic systems include a disposal field comprised of a mixture of sand, silt, and clay that are often referred to as loamy soils that act to successfully treat bacterial and inorganic compounds. Phosphorus that is produced within the household that passes through the septic tank is also captured within a properly designed disposal field’s soil.

On-site waste water disposal systems continue to be installed in support of residential and commercial development that occurs in rural settings where sanitary sewer systems are not available. According to Michigan State University Extension, when an on-site waste water disposal system is correctly located, properly designed, carefully installed, regularly inspected, and properly maintained, they serve as effective waste disposal systems that are economical and that do not pose a threat to public health or to the fragile ecosystems of surrounding streams, rivers, and lakes.

The gravity of the situation in Michigan is also effectively illustrated by the fact that the results of a 2015 study conducted by Michigan State University researchers on sixty-four Michigan rivers revealed that concentrations of e-coli that were higher than U. S. Environmental Protection Agency permitted water quality standards. The significance of the issue is also amplified by the fact that the Michigan Department of Environment, Great Lake, and Energy (EGLE) reports that approximately one half of Michigan’s thousands of miles of rivers and streams suffer from concentrations of toxic e-coli that exceed minimum water quality standards.

Michigan’s Inland Lakes: Vital Economic Engines

Created by the glaciers that gradually receded from North America’s Great Lakes region more than ten thousand years ago, inland lakes grace Michigan’s unique landscape like sparkling jewels. Thousands of inland lakes of all shapes, sizes, and depths play a distinctive role in making Michigan a beautiful place to live, work, and engage in water-borne recreational activities. In addition to enhancing the natural beauty of our freshwater-centric state, inland lakes contribute an extraordinarily valuable array of economic benefits to Michigan by:

  • providing high quality recreational opportunities for millions of our fellow citizens and visitors to our magnificent state
  • enabling lucrative inland lake dependent business opportunities for thousands of entrepreneurs
  • supporting premium lakefront living lifestyles and enhanced riparian property values that benefit hundreds of local communities and public schools
  • enhancing the aesthetic appeal and therefore the economic viability of near-by villages, towns, and urban areas

Moreover, by enabling popular water-borne recreational activities such as boating, fishing, and waterfowl hunting, our inland lakes play a vital role in helping to promote and sustain market driven economic expansion by stimulating the demand for new lakefront and/or near shore businesses as well by contributing to the prosperity and growth of nearby communities. Generating tens of billions of dollars in annual economic activity, our natural treasure of thousands of high-quality inland lakes are vital economic engines that will ultimately play an important role in helping to create and sustain the robust “blue” economy that will help ensure a productive and prosperous future for coming generations of Michigan’s citizens.

Successful May 21st 2025 Lake Awareness Day Event Seeks to Draw the Attention of State Officials to the Vast Economic Contributions of Michigan’s Inland Lakes

For the third consecutive year, a collaborative partnership planned and implemented Lake Appreciation Day was dedicated to helping educate officials from Michigan’s Governor’s office, State Senate, and House of Representatives in regards to the immense ecological and economic value of our inland lakes and their vital role in contributing to Michigan’s ‘blue’ economy and culture. The need for the Governor’s office and the state legislature to begin working together to enact state laws intended to protect the long-term ecological viability of our inland lakes while at the same time significantly increasing public investment in statewide programs implemented to help preserve and protect their increasingly vulnerable aquatic ecosystems is emphasized to those in attendance. It is also important to note that those in attendance at the late morning, early afternoon event enjoyed a catered lunch.

Participants in the Wednesday, May 21st 2025 Lake Awareness Day that was held at the corporate offices of Karoub Associates located near the state capitol building in downtown Lansing included Senators, Representatives, and/or staff members representing Michigan’s state legislature, state natural resource and environmental protection agencies, inland lake conservation focused non-profit organizations, and lake management focused commercial businesses that each hold a vested interest in preserving and protecting Michigan’s vast treasure of inland lakes. Participants in the 2025 Lake Appreciation Day program included:

2025 Lake Appreciation Day event planners are committed to a plethora of scientific evidence that strongly suggests that the long-term capacity of many of Michigan’s extraordinary inland lakes to continue making vital contributions to our economy and culture are contingent upon the capacity of state government to enact state laws focused upon:

  • Protecting both the short and long-term ecological health of our inland lakes and wetlands;
  • Establishing and administering a statewide septic system code;
  • Increase funding to establish and expand MDNR and EGLE programs dedicated to inland lake stewardship, restoration, and aquatic invasive species prevention and management;
  • Establishing and administering alternative sustainable means of increasing funding for inland lake conservation and aquatic invasive species prevention and management efforts;
  • Educating riparians and near shore businesses with regard to the need to implement inland lake Best Management Practices and encourage their pro-active involvement in inland lake restoration projects.

Legislation Seeks to Deregulate Disposal of Livestock and Slaughter House Hazardous Waste By-Products

by Scott Brown

MWA e-Newsletter Editor

The Michigan Board of Directors recently voted to pro-actively oppose legislation introduced in the Michigan House of Representatives that if passed into law would allow extraordinary amounts of livestock manure, urine, blood, and blood stained water generated by Concentrated Animal Feeding Operations (CAFOs) and slaughter houses throughout the state to be spread unimpeded on millions of acres of Michigan farm land and therefore indirectly into the vital freshwaters of our lakes, rivers, streams, and wetlands.

Recently introduced in the Michigan House of Representatives, if passed into law, House Bill 4257 and House Bill 4265 would act to effectively deregulate the high volume of hazardous waste that is generated annually by Michigan’s large scale livestock feeding and slaughterhouse operations. Under current Michigan law the Michigan Department of Environment, Great Lakes, and Environment (EGLE) strictly regulates the high volumes of toxic waste that is generated by concentrated animal feeding operations and livestock slaughter houses under Part 31 (Water Resources Protection) of the Michigan Natural Resources and Environmental Protection Act (MI NREPA).

It is important to note that Michigan CAFOs are responsible for creating 4 billion gallons of untreated urine and feces and 40 million to 60 million tons of solid manure each year that subsequently gets spread on 600,000 acres as water polluting, algae growth stimulating fertilizer – a harsh fact that if often repeated by those involved in protecting Michigan’s extraordinarily valuable freshwater resources, and as a blunt argument in support of the ultimate defeat of MI House Bills 4257 and 4265.

Our readers should know that livestock manure contains toxic levels of nitrates, phosphorus, and harmful E. coli bacteria that has contaminated surface and groundwater resources across Michigan. The heaviest concentrations of CAFO generated livestock manure is generated in areas of the state hosting large industrialized livestock and poultry operations. Discharges from Michigan CAFOs, for example, are known to contribute to high volume concentrations of phosphorus-laden pollution that causes widespread toxic algal blooms each summer in Lake Erie.

Michigan Waterfront Alliance believes that each of the Bills violates both Michigan and federal law, including a fairly recent Michigan Supreme Court opinion that MI EGLE is within its regulatory authority to regulate the high volume of toxic waste that is created each year in large scale livestock feeding operations and livestock slaughter houses. Michigan Waterfront Alliance also believes that passage of the misguided legislation would endanger Michigan’s delegated authority under the federal Clean Water Act to administer its own National Pollutant Discharge Elimination Systems (NPDES) permitting program.

It is important to note that Michigan Waterfront Alliance is joined by several other well known state environmental protection focused organizations including the Michigan Environmental Council and Michigan Lakes and Streams Association in pro-actively opposing the irresponsible legislation.

The ‘Not So Great Lakes State’ that Continues to Allow Billions of Gallons of Toxic Raw Sewage from 300,000 Dysfunctional Septic Tanks to Pollute Thousands of our Immensely Valuable Lakes, Rivers, and Streams

by Scott Brown

MWA e-Newsletter Editor

For those of us who recognize the immense value of the multi-faceted contributions that our inland lakes and rivers make to Michigan’s increasingly ‘blue’ economy and culture, the failure of our state legislature to enact legislation that would have established a statewide septic system code represents represents a tragedy of increasingly dire proportions. Strident opposition from county health departments, the real estate industry, and from “don’t tread of me” politicians who believe that any form of environmental regulation represents a threat to the exercise of individual liberty, helped ensure that the common sense legislation that was introduced in the last session of our state legislature did not even come up for an up or down vote.

For the Great Lakes state whose vast natural heritage of immensely valuable freshwater resources – our extraordinary inland lakes, rivers, streams, wetlands and groundwater aquifers that contribute billions of dollars of vital services to Michigan’s economy – we find ourselves in the embarrassing and increasingly dangerous predicament of being the only state in the United States of America who continues to allow billions of gallons of raw, toxic toilet bowl waste to flow unimpeded into our precious freshwaters each year from hundreds of thousands of dysfunctional septic tanks.

Representing a increasingly dire threat to the health our citizens and to the innate capacity of our freshwater resources to continue to provide immensely valuable economic and ecological services to Michigan’s increasingly blue economy, our collective lack of willingness to enact and enforce a common sense statewide septic system code has already resulted in the fact that many of our rivers and streams host levels of e-coli and other pollutants, including PFAS, that represent a serious threat to the health of anyone who comes into contact with what represents an increasingly toxic brew of life threatening substances. This author is reminded of the intensely polluted rivers that flow through heavily populated urban areas of India where even momentary contact with the water threatens the onset of severe illness or death.

The enactment and implementation of a well funded, common sense statewide septic system code will go a long way to helping resolve the fact that one quarter, or 330,000 of Michigan’s 1.3 million septic tanks spill almost six billion gallons of E. coli and harmful chemical contaminated wastewater into our freshwater treasures each year due to the fact that they have not been properly maintained or pumped out on a regular basis. The severity of the problem in Michigan is effectively illustrated by the fact that roughly half of our rivers and streams have been contaminated with human fecal matter derived Escherichia coli (E. coli) bacteria levels that greatly exceed the minimum concentrations that are known to be responsible for the onset of a dangerous array of debilitating human diseases.

It is also important to note that the overall ecological health and water quality of thousands of our inland lakes is also threatened by the extreme levels of water clarity threatening phosphorus and nitrogen that originates from tens of thousands of near shore residential septic tanks that have not been properly maintained in decades. The increasing frequency of toxic blue-green algae blooms, also known as cyanobacteria, that are observed in Michigan represents a reliable indicator of the increasingly dire need to remedy a situation that allows billions of gallons of toxic raw sewage from 300,000 dysfunctional septic tanks to flow into our precious freshwaters each year.

It is important to point out that the Great Lakes state – Michigan, endowed with a vast treasure of life sustaining freshwater, is the only state in America that has not established a statewide code for regulating the construction. inspection, and periodic maintenance of septic systems. In the continued absence of a statewide septic system code, only 11 of Michigan’s 83 counties have passed local ordinances that regulate the construction, inspection, and maintenance of residential septic tanks and their associated drain fields.

For those of us who understand and appreciate the vast contributions that our freshwater resources make to Michigan’s ‘blue’ economy and culture, it is difficult to understand how otherwise responsible state legislators can allow hundreds of thousands of failing septic systems to continue to degrade tens of thousands of freshwater ecosystems – our lakes, our rivers, our streams, our creeks, our wetlands, and our ground water aquifers – while at the same time presenting a significant health threat to the people of Michigan.  Readers of this newsletter can be assured that Michigan Waterfront Alliance will continue our pro-active efforts to convince state law makers of the increasingly dire need to enact legislation that would establish a state septic system code.

Readers of this newsletter are encouraged to contact their respective state representatives or state senator to encourage them to support the enactment of a statewide septic system code – the capacity of our freshwater resources to contribute to a healthy, prosperous ‘blue’ economy and culture for future generations of Michigan citizens depends on our success!

The Onset of Spring and Warming Water Temperatures Prompts the Annual Spawning Cycle of Bluegill, Largemouth Bass and Other Sunfish Species in the Shallows of Thousands of Michigan Inland Lakes

Wise Lake Associations Identify and Protect Vital Sunfish Spawning

Beds from the Harmful Influences of Recreational Boaters and Fisherman

Occurring in response to longer periods of daylight and as the gradually warming water temperatures of mid-to-late spring and early summer reach 60 to 70 degrees, several members of the sunfish family that inhabit thousands of Michigan’s inland lakes including bluegill, red ear sunfish, pumpkinseed, green sunfish, and largemouth bass migrate from their deep water winter habitat to areas of their lake hosting shallow waters to begin their annual spawning cycle.

Sunfish spawning beds are most often observed near the outer most edges of aquatic plant meadows and/or near areas of the lake’s bottom hosting woody debris in water depths ranging from eighteen inches (1.5′) to five feet (5.0′). Sunfish spawning beds often consist of hundreds of nests lying in close proximity to one another. Sunfish spawning beds are often located near submerged aquatic plant meadows or areas hosting woody debris due to the fact that the complex habitat provided by aquatic plants and/or woody debris plays a critical role in helping to sustain inland lake fish populations by forming protective habitat that allows hatchling and juvenile fish to avoid predation, and by providing a prey rich environment that enables the fledgling ability of young fish to successfully forage for life sustaining food.

The annual spawning process begins as the male of the species uses his pelvic, anal, and tail fins to create gravel and stone filled depressions that serve as protective nests in the sediment. It is important to point out that the act of creating a nest is often sufficient for the male sunfish to attract a suitable female mate. The reproductive process continues as the female deposits thousands of tiny eggs into the protected interstitial spaces that lie between the gravel and stone within their nests. With her critical role now complete, the female of the species leaves the spawning area . In addition to continuing the reproductive process by fertilizing the eggs within his nest with his sperm, the male of the species pro-actively protects the now fertilized eggs by hovering over the nest and aggressively chasing away hungry predators seeking a protein rich meal consisting of fish eggs, and by using his tail to prevent sediment from accumulating on the now fertilized eggs in the nest (see the photo above). The male continues to protect his nest up to the point that the eggs develop into tiny hatchlings that are capable of venturing into protective habitat comprised of nearby aquatic plant meadows or areas hosting woody debris that also provide a prey rich environment that enables the fledgling ability of young fish to successfully forage for life sustaining food.

Concentrated in shallow areas of inland lakes protected from wind and waves, sunfish spawning beds often consist of hundreds of individual nests that during late spring and early summer are each tended to by adult male sunfish. It is important to point out that sunfish spawning beds are highly vulnerable to damage and the potential loss of millions of developing eggs due to the propeller wash of watercraft operating in shallow waters. The turbulence created by prop wash acts to flush tiny fish eggs out of their protective nests – thereby destroying the eggs and/or making them vulnerable to being consumed by predators. The adult males that protect each of the nests are also highly vulnerable to being caught by recreational fisherman – the loss of the nest’s protective male all but ensures that the eggs within the nest will be consumed by predators or smothered by sediment.

Lake associations, individual lake users and recreational fisherman can help support the capacity of our bluegill, our red ear sunfish, our pumpkinseeds, our green sunfish and our largemouth bass to successfully reproduce by:

  • Identifying areas of their lake hosting sunfish spawning beds and by taking steps to protect sunfish spawning beds and the fish engaged in the annual reproductive cycle;
  • Refraining from operating their watercraft in shallow areas of inland lakes that may be hosting sunfish spawning beds;
  • Supporting spawning sunfish by not fishing in areas of the lake hosting spawning beds;
  • Not taking the maximum number of sunfish allowed under Michigan law – taking the maximum number of fish allowed under the law is not a sustainable practice – by practicing “catch and release” you help ensure sustainable populations of largemouth bass, bluegills, and other sunfish species into the future;
  • Practicing “catch and release” in late spring and early summer in order to protect male sunfish that maybe pro-actively engaged in protecting their nests;

It is important to note that lake associations seeking to protect and support the reproductive efforts of the several sunfish species that inhabit most of our inland lakes should seek to educate their members in regards to the presence of spawning beds and the need to help protect those areas in late spring and early summer in order to help ensure the continued existence of a healthy, diverse fishery. Lake management companies are capable of identifying areas of your lake hosting sunfish spawning beds.

Once Abundant “Wolf of the Weed Beds” – Northern Pike – Continue to Suffer Steady Decline or Extirpation in Southern Michigan Inland Lakes

by Scott Brown

MWA e-Newsletter Editor

Often referred to as the “wolf of the weed beds” due to the lightning fast manner in which the opportunistic and always voracious freshwater carnivore “dispatches” its unwary prey, northern pike, scientific name Esox Lucius, feeds on frogs, torpedo shaped fish such as yellow perch, the hatchings of ducks and geese, and small animals such as voles, shrews, and juvenile red squirrels. Capable of growing to lengths of up to 4.5 feet (1.37 meter) and achieving weights of up to 62.5 pounds (28.4 kilogram), northern pike possess long hydrodynamic bodies that allow them to move quickly through the water, powerful duck bill-like jaws that nature has equipped with an impressive set of razor-blade sharp teeth, and large, light sensitive eyes that allow the efficient aquatic predator to effectively pursue its prey based upon visual stimuli alone.

Capable of living as long as fifteen years, northern pike have an average life span of six to eight years. Due to their non-stop voracious feeding habits, northern pike are known to obtain much of their length and weight in the first two to three years of life. The females of the once abundant predator become sexually mature at three or four years, while the male of the species reaches sexual maturity in two to three years. Northern pike found in Laurentian Great Lakes region inland lakes and rivers spawn soon after “ice out” in late March, April and May.

Optimal northern pike habitat continues to be found in Arctic and boreal regions of North America, Europe, Asia, and Siberia that are defined by vast expanses of coniferous forests, wetlands, and thousands of relatively unperturbed inland lakes, rivers, and streams. Ideal northern pike habitat is comprised of large, moderately productive, aquatic plant dominated inland lakes hosting natural shorelines, log jam created pools found in rivers, and the isolated, prey rich backwaters of creeks.

While once thriving populations of northern pike continue to fade within the inland lakes and rivers of southern Michigan due to widespread loss of natural shorelines, woodlands, wetlands, and the harmful influences of water clarity depriving nutrient driven eutrophication, northern pike, along with walleye, continue to be the primary targets of a thriving fly-in recreational fishing industry that continues to operate on relatively large pristine inland lakes found within the Canadian province of Ontario lying just north of Lake Superior.

It is important to note that due to the capacity of northern pike to dramatically alter the food web of freshwater ecosystems as a result of non-stop voracious feeding, the species is considered invasive in some regions. A native of interior and western Alaska, for example, northern pike were illegally introduced to the Susitna River basin in the 1950s. In the 70 years since its illegal introduction, the highly invasive predator has become well established in more than 150 lakes and rivers located in Alaska’s south central region which also includes the Kenai Peninsula.
