Fall 2017/Spring 2018 Summary: (report will be published when electronic version is available)

·         Data available dating back to 1979 from prior Dr. David Jude studies.

·         Data correlation to improved water conditions, including clarity, since installation of the Runyan Lake sewer system in the late 1980’s.

·         Dissolved oxygen still low at depth, but enough to prevent phosphorus spikes resulting from decaying plant material on the lake bottom.  This helps minimize aquatic weed growth.

·         Water quality generally healthy, but evidence of increased sodium (salt) content from winter road salt runoff.

·         Potential reduction of Yellow Perch, Lake Herring, other species, as a result of prior stocking of Walleye.

·         Fish diversity has been slowly recovering during the last 10 years, lack of mature Yellow Perch population still of concern.

·         Other species appear to be in much smaller quantities versus historical data, or no longer existent (Pike, Garpike, Lake Herring, Rock Bass). * note – Pike and Garpike observed during fishing contest and 2018 breeding seasons but size and numbers suggest a decline in population)

·        General lake health is good. Recommendation is to continue to allow for natural recovery.  No fish stocking.  Stocking will adversely affect the competitor species to whatever is stocked.

·         Residents strongly encouraged to eliminate fertilizer runoff (don’t fertilize grass on the waterfront side of your property), and no burning of grass and leaves to prevent fertilizing the lake (note – effective 2018 it is now illegal per local ordinance to burn grass and leaves in our immediate area).

·         Strongly encouraged to aggressively manage existing invasive species (Eurasian Milfoil, Starry Stonewort), and prevent other invasive species (goby, Quagga mussels) from neighboring lakes.
