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.
