Fall Turnover at Lake Mohawk
Based on recent oxygen/temperature readings, Lake Mohawk has started it's Fall turnover process where deep cooler water and warmer upper water now begin to mix. Cooler nights initiate this process by cooling upper layers of water which causes the upper layers to sink due to density changes. As the temperature differences between the upper and lower layers of water become similar, wind currents create a large cycling of water between the surface and bottom of the lake. This is a natural and healthy cleansing process by which deeper water now becomes re-oxygenated enabling fish to live in deeper areas of the lake for overwintering.
NOTE: Several TEMPORARY negative effects of Fall Turnover include algal blooms caused by phosphorus rich deep water (hypolimnion) being cycled to the surface where it can "feed" blue-green algae (cyanobacteria). Fishing characteristics of the lake changes during this period. Fish are now moving to different parts and depths of the lake that they were previously unable to live due to low dissolved oxygen.

Lake Management Strategy 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 , 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.. 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. E-mail: GraysAquatic@gmail.com or Cell: 330.412.4139
Myriophyllum sp. (heterophyllum) (left) Potamogetan crispus (right)
The normal predominant May aquatic plant has been Curlyleaf pondweed (CLP) (Potamogetan crispus) (right) for the past 13 years. Due to a variety of environmental changes in lake sediment type due to dredging and early species competition from CLP Myriophyllum sp. (Water milfoil) has become the dominant aquatic plant species for 2022.
NOTE: Curlyleaf pondweed naturally dies off in mid-June Provides early nesting, protection, and food base for a healthy fisheries. This plant is intentionally selectively managed/controlled.
The Relationship between Aquatic Plants & Water Clarity
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 is 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 the 2017 lake season, nuisance levels of aquatic plants will be selectively controlled in specific areas where it most interferes with recreational use of the lake.
