What do these fishing results say about the "Health" of Lake Mohawk?

(see answer below)




2016 Lake Season

"State of the Lake Address"


One of the easiest and most accurate methods of judging the health of a lake is to

evaluate the living organisms that live there on a 24/7, 365 days a year basis.  The fisheries within Lake Mohawk for

example must rely on healthy conditions in the lake throughout the entire year to grow and reproduce.  No single test, set of tests, or short term human observations can accurately asses the lake better than evaluating the fisheries within that particular lake. 


Chris and Duane's end of the season fishing results (listed above) as part of the Lake Mohawk Sportsman's Club weekly fishing tournaments is a strong indication that Lake Mohawk is doing very well in terms of overall ecological "health". 


"Joe Jacko - Sept. 27, 2016 E-mail referring to Chris and Duane's results

"In my 17 years at the lake I have never seen a bag (5) of fish like this"


Independent fishing results and surveys are also helpful in determining the overall health of the lake and fisheries.


"Donna Vansickle - Sept 23, 2016 E-mail"

"We were out yesterday for 4 hours. Caught 51 fish including a large perch a gill. Caught 2 - 16" bass and a 19" all nice and fat. Got 13 (bass) total.  Also got another walleye 21", and a nice 16" smallie along with a bunch of bluegills and crappie.


Note: Care must be taken when evaluating fishing results because conditions within a lake can change

that favor one type of fishing method over another. For example, increased aquatic plant growth can

make fishing more challenging due to both physical reasons (hook becoming snagged) and biological reasons

(fish feeding/hiding in cover, etc).



2016 at Lake Mohawk was a lake season full of challenges for several reasons which included:


  •  A mild 2015/2016 Winter (Resulting in the expansion of the Spring/Early Summer Aquatic Plants)

  • Record breaking heat (hottest August on record) (Conducive to Blue-Green Algae/Cyanobacteria)

  • Minimal Summer Rainfall (lake level, nutrient concentration)

  • The expansion of a tall native aquatic plant (Slender Naiad) in many of the bays (plant cuttings)

Managing a lake with multi users (skiing/fishing/tubing/jet ski/swimming, etc) such as Lake Mohawk is an extremely challenging task.  There are many variables throughout the season that must be dealt with in a relatively

short period of time.  Making things even more complex is the fact that "Mother Nature" is not predictable.


2016 Plant Cuttings (the management dillema)


The most often human judged condition of a lake is that of the existence or absence of aquatic plants and algae.  For

that reason, lake conditions will be judged differently by various individuals at any given time.  For example, the

unexpected 2016 expansion of a taller native aquatic plant known as Slender Naiad resulted in plant cuttings floating to various shoreline areas in mid July-early August).  While the simple solution would appear to be chemically treat the plants before they were cut by propellers,  the "resultant reaction" had to be taken into account, especially during a

hot dry season which was conducive to blue-green algae (cyanobacteria) growth.  Chemically controlling too many aquatic plants in a short period of time during the summer months has a high potential to initiate a blue-green algae bloom.  Toxic

blue-green algae blooms can "close" a lake to public contact.  For that reason, the decision was made to slowly control the expansive Slender Naiad population to minimize the chances of a potentially toxic algal bloom. 


Summary of 2016 Lake Season


Spring through early summer at Lake Mohawk went well in terms of nuisance free conditions from aquatic plants and algae despite the mild winter of 2015/2016.  The water was clear and nuisance free from mid May (Memorial Day) through July 4th and beyond.  As the growth of Slender Naiad continued to grow in July, the water remained clear and free of blue-green algae.  Naiad plant cuttings became a nuisance along some shoreline areas due to ideal growth conditions (clear water/sunny days/warm water) and increased boat traffic.  Toward the end of July, increased chemical control in the central portions of selected bays reduced plant cuttings significantly to non-nuisance conditions. 


2016 ended in a year without any significant blue-green algae blooms that could have potentially closed the lake.

In addition, 2016 marked a season in which a very aggressive exotic plant known as Eurasian watermilfoil was almost

non-existent in the lake.  A true testament to the ecological approach of native aquatic plant competition.  Although fishing became more difficult with the expansion of the aquatic plant population in mid-summer (when fishing also slows down naturally - "The dog days of Summer"), the fisheries was thriving and well as evident by late season fishing results.


The lake season at Lake Mohawk is ending with a "gentle Fall turnover" as evident by the oxygen/temperature profiles. Also, the fisheries will be going into winter with an adequate food supply considering the fact that nuisance aquatic plant and algae control was applied at a time and manner that had minimal impact on their food supply.  All in all, 2016 (IMHO)was good year considering the number of variables and challenges that we all had to deal with.

Fall Turnover at Lake Mohawk has Arrived



Fall turnover in a lake begins when the temperature gradients within

the lake move closer together until the lake water temperatures

between the surface and the bottom of the lake are nearly the same (isothermal).


As warm less dense water (0-12 ft. at Lake Mohawk) begins to cool, thermal

vertical currents begin to disrupt the thermocline which results in

mixing between the upper strata of water (epilimnion) and

the lower strata of water (hypolimnion) from wind and density differences

within the water column. 

The complete Fall turnover process can take many  weeks to a month or more to

fully complete depending on weather conditions within that season.   




Referring to the August 12th and August 18th oxygen/temperature data below,

note how the temperature in the lake from the surface (0 ft.) through 9 ft. has declined

an average of 3 degrees in a one week period.  August 12th marks the peak temperatures

in the upper strata of the lake (epilimnion) for the 2016 lake season.


Also Notice how the weak thermocline (a significant temperature gradient between two depths)

  that existed between 9ft. and 12 ft.  (83.5 / 81.7 respectively)  on August 12th has "disappeared"

within one week of the August 18th measurements. (80.8 / 80.8 respectively).


In addition to temperature changes the dissolved oxygen concentrations

at 12 ft. and 15 ft. on August 12 andAugust 18 have changed significantly.

(3.6 increasing to 7.0 at 12 ft.  and 0.5 increasing to 2.4 at 15 ft.).


Dissolved oxygen is now increasing in the deeper portions of the lake which will have a direct

impact on fish distribution within the lake.  Fish will now be able to thrive in a greater

volume of water.  This change in fish distribution will affect fishing in that techniques

used to catch fish in the summer may not be as effective as those needed to catch fish in the Fall.




Other Affects of Fall Turnover


Fall turnover affects a lake in other ways than just temperature and oxygen as mentioned above.


  Fall turnover is sometimes referred to as a "natural cleansing" process of the lake

 whereby "bottom water" (hypolimnion) that is low in oxygen and high in nutrients and other

byproducts of bacterial decomposition such as hydrogen sulfide are mixed in the upper

strata where oxygen "detoxifies" the water.  Having the "bottom water"  detoxified is

critical to supporting fish and other aquatic organisms through Winter ice on conditions. 


One of the biological affects of turnover is the mixing of phosphorus into the upper  water layer (epilimnion)  of the lake which contributes to August/September blue-green algal blooms.  Fortunately however, there is a relatively complex but important reaction that occurs between phosphorus and dissolved iron in the presence of oxygen in a lake that helps bind phosphorus thereby making it biologically unavailable to algae over time. (Ferric Phosphate Reaction).


(NOTE: Fall pollen at Lake Mohawk is also believed to be a significant source of phosphorus) 


As the graph below indicates, August/September is a natural peak period for blue-green algal

populations in most all lakes.  











Lake Mohawk 2016


"Behind the Scenes Look of What You May Not Know"

(August 2016 Blog)


Lake Mohawk as I have mentioned many times remains one of the

most pristine lakes in Ohio in terms of water quality as measured by

water transparency, aquatic plant species, fish populations, and a whole host

of other biological indicators.  Despite the fact that Lake Mohawk is a very high quality lake, there are threats that do exist that can adversely affect both the lake and human safety.


One of the most significant threats to all lakes including Lake Mohawk is the potential for toxic blue-green algal blooms.  A secondary long term threat to the ecology of  Lake Mohawk is the algaecide (copper sulfate) that is used to control blue-green algae blooms.  Continued use of copper sulfate can lead to "copper bottom" lakes that do not support plant life in addition to being toxic to food organisms that supports a healthy fisheries.   The eventual result of a "copper bottom" lake is having a lake that can only supports algal blooms with little or no plant growth.   Light penetration into the water can become so limited that aquatic plants will no longer grow resulting in algal blooms and a stunted undesirable fisheries.

An example of a "sister lake" to Lake Mohawk

(both lake communities were constructed by the same developers)  that CANNOT support aquatic plants is Lake Choctaw located in London, Ohio.  

Water clarity in this lake is most often between 12-18 INCHES.


Starting in 2009, it was decided by a dedicated group of people on the Lake Committee and

Board of Directors to prioritize lake management objectives which included a variety of

"lake restoration" and "protection" measures.  At that time, it was decided that the

control of potentially toxic blue-green algae that could "close the lake" to water contact

activities was a "top priority".   An associated priority was to reduce the use of copper

sulfate that would eventually destroy the overall ecology of the lake which in turn would

adversely affect property values.    Although non-copper based algaecides do exist

(Green Clean for example), they were found to be too cost prohibitive for a 500+ acre lake.

The most feasible natural low cost alternative for reducing algal blooms is to

utilize natural aquatic plant populations in the lake.  Aquatic plants compete for phosphorus,

stabilize phosphorus containing sediments, and may secrete inhibitory chemicals against

phytoplanktonic algae responsible for algal blooms.   While this method is very effective, it

is not without it's drawbacks especially in a lake with many shallow bays with high

levels of recreational activities from propeller driven watercraft.   The negative

affects are of course plant cuttings from plants that have a taller growth structure.  

Selective chemical methods and herbicides have been effective at changing the

aquatic plant community from that of exotic non desirable aquatic plants (Milfoil for example)

 to native species such as Slender Naiad.  Slender Naiad unfortunately has a flowering stage

in July that grows in the shallow bays and is easily cut from boat traffic if left untreated.

The dilemma here therefore is to either leave the flowing Naiad untreated, which then often ends up as a mass of cuttings in front of a lakefront property owners or to treat the plant which

significantly contributes to the chances of a blue-green algae bloom.....especially in a

hot, dry, sunny summer season like we are experiencing in 2016.


THE IDEAL SOLUTION to the above situation IF MONEY were NOT a factor

would be to mechanically harvest

(NOTE: it would require several harvesters and a transport barge)

the tops of the Slender Naiad


deepen the bays through dredging

in which the depth would either be limiting to the plant or the plant would grow deep enough that it would not be cut off by boat propellers.    FYI, dredging the bays is currently under

intense and diligent study by the Lake Committee with significant progress being made.  Until

more permanent solutions are implemented such as dredging, please know that herbicidal control of slender naiad has been extensively applied in the last several weeks that will significantly reduce cuttings while attempting to maintain the deeper growth

that does not interfere with recreation but still helps in reducing blue-green algae blooms.   


Most people will never realize the dedication and time that the Board of Directors,

the Lake Committee, Lake Manager, and many other volunteers put in to insure the overall safety, satisfaction, and enjoyment of all members of the L.M.P.O.A. throughout the year.  Personally, I am most impressed on how thorough and frugal these individuals are

at managing and examining alternatives to accomplishing potentially very expensive projects.

Furthermore, all of these individuals bring a wide variety of professional backgrounds and

experiences that benefit the entire L.M.P.O.A. community.  Please know that It is a pleasure to serve a community that supports sensible lake management goals that will affect both current and future generations.   On behalf of myself and others, your understanding and support is

sincerely appreciated.

 If you have any questions, please do not hesitate to contact me at your convenience.







The Relationship between Aquatic Plants & Water Clarity


As we enter the months of July and August at Lake Mohawk, I believe it is important to have a basic

understanding of the important role of submersed aquatic plants as it relates to water clarity.

While many of us may know about the importance of aquatic plants to fish populations, it is

lesser known about how aquatic plants help maintain water clarity and purity.


Besides providing food and habitat for fish, aquatic plants stabilize lake sediments that are

high in phosphorus.  Phosphorus that is mixed up from wind, wave, and other recreational

watercraft traffic "feed" undesirable algal blooms that reduce water clarity.  In addition,

aquatic plants utilize and compete for available phosphorus making it less available to

the tiny planktonic algae.  There is also some evidence that aquatic plants

secrete inhibitory chemicals that reduce algal blooms.


Our lake management goal at Lake Mohawk has been to balance the needs and wants of a

variety of recreational users and property owners throughout the season without jeopardizing

the long term health of the lake.  Using aquatic plants as much as possible to

reduce the intensity of algal blooms, reduces the need for ecologically undesirable algaecides.

Throughout this next two months, nuisance levels of aquatic plants will be selectively

controlled in specific areas where it most interferes with recreational use of the lake.  All

attempts will be made to assure that boat and jet ski access to and from the main body

of the lake is clear of nuisance growth.  Areas with swim platforms will also be targeted for

selective control.   In areas where it is believed that aquatic plants to do not significantly

interfere with recreation, aquatic plants will be left to grow to help in the natural

suppression of undesirable algal blooms....not to mention the benefits to the fisheries.

Great looking fish guys!!!  Glad to see you're having fun!!!






Water Clarity & "Mother Nature"


I received an e-mail the other day from Donna VanSickle who is without out a doubt

one of the most.... if not the most..... avid fisher"woman" at Lake Mohawk. 

Donna and her "fishing buds" as she calls them can often be seen in their pontoon boat fishing the entire shoreline and open waters of Lake Mohawk.

Donna's keen awareness of the lake provides me with valuable

feedback about the "health" of the lake through her observations on fish counts and

changes is lake water conditions.


Donna recently sent me a complimentary thought provoking e-mail that I would like to share as

it had some important points to be aware of as we quickly approach the summer months

of July and August.

(e-mail below)


While I truly appreciate her comments such as

 "The water looks great" and "Thanks for all you do!"

I would like all L.M.P.O.A. members to know that it is not so much what I do.....

it is more what "Mother Nature" does.  The only thing that I do is to

try and work with "Mother Nature" to the extent that I can, to make Lake Mohawk a safe

and enjoyable recreational lake for many years to come.

To: Jeff Gray <>

"Me and the fishing buds were out today for 5 hours.  The water looks great!  So clear and clean.  Our total count was 127 fish including 20 bass, 92 crappies, mostly 9-12 " but one 13", some blue gills and perch and one 23" pike.   It was a good day!   Thanks for all you do!  Donna"



  "The water looks great!  So clear and clean."

As Donna has observed, Lake Mohawk is one of the most pristine lakes in Ohio

as measured by average secchi disc depth (2011 C.L.A.M.) 


 Even though Lake Mohawk is one of the clearest lakes in Ohio on average,

it is still subject to the ecological changes of "Mother Nature". 

One of those seasonal changes is known as  "Algal Succession" (figure 19)


Please know that water clarity in Lake Mohawk will continue to decrease as we head into

July and August.  This decrease is perfectly normal for most all Ohio lakes.

The decrease in water clarity is due to a variety of reasons

including an increase in not only phytoplankton, but also from the microscopic "animals"

(zooplankton) that feed on these plants along with pollen, sediment suspension

from wind and boat traffic, etc..  


The important thing to remember is that phytoplankton play important roles in the overall "health" (ecology) of Lake Mohawk in a variety of ways including being a part of the fisheries food chain, oxygen production, natural shading/suppression of nuisance aquatic plants, etc..

Lake Management Philosophy and Mission Statement 


 By working with "Mother Nature", you can enhance the recreational value of freshwater aquatic ecosystems such as Lake Mohawk.   Selective and judicial use of aquatic herbicides which promotes natural competition from native low growing aquatic plants is part of an integrated approach to improving property values, sport fisheries, as well as recreational usage from skiers, pleasure boaters, etc..  Studying and controlling the sources of phosphorus will also naturally reduce or eliminate the threat of toxic blue-green (cyanobacteria) algae blooms.   The Lake Management Committee at Lake Mohawk (click), consisting of dedicated members of the L.M.P.O.A. from a variety of backgrounds is vital to the success of any lake management program.  Your support for this group of people is truly appreciated. 


My mission at Lake Mohawk is to serve, share knowledge, and answer all questions about the aquatic ecosystem that is the focal point of this beautiful lake community.  It is my desire to further enhance the existing fisheries while minimizing any negative impacts this may have on recreational boating, etc..  Monitoring the "health" of the lake and posting my results on this web site is also a priority.  Above all, I am here to serve the greater good of the Lake Mohawk Property Owners Association and will at anytime be available to answer questions or to respond to concerns or observations regarding lake conditions.



Lake Ecology


Human health and property values of ALL  L.M.P.O.A. members are affected by the water quality of Lake Mohawk.   In order to understand the various factors that have the most impact on the lake, I have constructed a diagram of interactions that exist between property owners, lake users, aquatic plants, blue-green algae, phosphorus, and copper.


Blue-green algae (photo below - microscopic "plant like" bacteria) blooms  are potentially harmful to humans and wildlife due to the production of toxins under certain conditions.   The severity of health impact depends on the type of toxin as well as the route of entry (ingested) or location of contact (skin/eyes). Blue-green algae may also negatively impact the ecology of the lake (i.e. fishing) by reaching a point where it shades out light to bottom growing beneficial plants.  For this reason, controlling blue-green algae in a manner that does not jeopardize the long term "health" of the lake (which directly affects property values) is the primary lake management objective at Lake Mohawk.



at Lake Mohawk


commonly known as

Curlyleaf pondweed or Mayweed

Potamogeton crispus - scientific name



Description -  Curlyleaf pondweed (CLP) is an interesting aquatic plant that begins it's life cycle during the Winter.  This plant begins growing under the ice from "seeds" called "turions".    From "ice off" (March) through the month of May, this plant can be seen growing in water depths from 3 feet to 10 feet throughout the lake.  This plant reaches it's peak density and height in May and early June where it then begins to "die off naturally" (senescence or end of life cycle).  By mid-to late June, most all of the CLP will have naturally ended it's life cycle. 


Ecological Importance of CLP to Lake Mohawk - Although CLP is actually an invasive/exotic species of aquatic plant (normally undesirable), this plant plays an important role to the aquatic ecology of Lake Mohawk.   More specifically, this plant is an important early "structure" in the lake which provides protection to young fish and acts as a "food substrate".  Many small aquatic food organisms live on and amongst the leaves of the CLP plant. 


The graph below (left screen) is a screenshot which illustrates the close association of fish and CLP within Lake Mohawk.


The "plumes" rising from 10 ft. of water depth up to about 4 ft. of water depth are

CLP plants.    The small fish pictures and associated water depths near the CLP illustrates the

close relationship of the plants and fish.  Lake Mohawk has very little in the way of

natural permanent structure which is important to a healthy fisheries. 





Management / Control of CLP at Lake Mohawk - Fisheries and Recreational Considerations 


Fisheries Considerations -As mentioned above, CLP naturally ends it's lifecycle in mid-June.  Spring spawning periods begin when water temperatures have reached 55-65 degrees for largemouth bass and bluegill normally spawn in June with multiple spawns possible through August.


Recreational Considerations -  Boating, Skiing, Swimming, Jet Ski's, Etc. -  Although CLP naturally dies off in mid-June, it is necessary to improve select areas of the lake with chemical control to avoid propeller entanglement,  etc. considering that lake use increases significantly beginning with Memorial Day.  


CLP Management / Control Objectives and Ramifications -  The chemical control of CLP is relatively easy and quick.  CLP is not resistant to chemical control provided the correct concentration and appropriate chemical(s) are utilized.  The three main considerations therefore for chemically controlling CLP involve:  1) Fisheries, 2) Recreational Considerations, & 3) Economics.  


The primary areas that are targeted for chemical control of CLP are "DENSE" areas of growth that are at or very near the surface in recreational boating and skiing areas.  Areas of CLP within the 80 ft. from shoreline zone (as marked by the floating buoys) are generally not treated UNLESS they are causing access issues for the lakefront property owner OR they are at the surface.  CLP plants that are at the surface within the 80 ft. zone are "top treated" to reduce the seed (turion) production of the plant.     "Top Treating" the CLP plant preserves the bottom portion of the plant for spawning fish, etc.. 


CLP plants that are sparsely growing in deeper water (8-10 feet) are not treated for a variety of reasons which includes economics and a low probability of becoming a nuisance.  Remember, ALL of the CLP will die off naturally in mid-June whether treated or not.


Please remember that the control of CLP has a degree of subjectivity.  The Lake Mohawk, Lake Restoration and Protection Committee is always active in monitoring the balance of the lake to serve all Lake Mohawk Property Owners.  Aquatic plants and algae change throughout the season just like land plants do.  Providing a healthy balance of nuisance free lake conditions involves a rather complex balance between man and environment.  Human health, property values, and your seasonal enjoyment of the lake remain a top priority of the Lake Mohawk Board of Directors, the Lake Mohawk, Lake Restoration and Protection Committee and myself.  Please feel free to contact me with any specific questions or concerns.

     Lake Trivia

The average thermocline in northern dimictic (two mixes or turnovers per year) lakes occurs around 12 feet of depth.  Dissolved oxygen declines rapidly below this depth.  


Lake Mohawk has  characteristics more like a reservoir than a natural lake which was formed by glaciers (glacial kettle lake)


The deeper northern end of the Lake Mohawk basin does develop a thermocline as the oxygen temperature information indicates.  This portion of the lake is responsible for summertime sedimentary release of phosphorus.
