beaver lake surveys - summer 2023

In the spring at ice-out, and in November at the end of the season, a sample of Beaver Lake water is taken and sent to the State Lab at UW Stevens Point. For several years now we have been gathering data as to phosphorus, nitrogen, etc. This allows FOBL to monitor trends in the Lake across these critical measures. Monthly, a disk is lowered into the Lake's deep pool to determine the clarity of Beaver Lake. This varies seasonally - and we have the data going back many years to track our water quality.

On a five year recurring basis, Friends of Beaver Lake commissions a study of the lake-bed to determine the types and extent of weeds in Beaver Lake. A vibrant plant infrastructure in the Lake provides so many benefits to wildlife, and is indicative of a healthy lake. It is another way to confirm the status of our living Lake.

In March, 2012, Friends of Beaver Lake commissioned a survey of the fish in the Lake. This is done just after ice-out using fyke nets set up around the shoreline. A detailed report is received and evaluated by the Conservation/Wildlife Committee along with our consultant, Cason and Associates. The sampled fish can tell us about the growth rates of the different species and their relative success in the Lake. This is another way to monitor the health of Beaver Lake.

In June, 2016, a shoreline test planting was done to begin to re-establish more shoreline plants into Turtle Bay and to evaluate the potential for successful planting at other shorelines around the Lake. Studies show that a shoreline (10-30 feet on land and out into the Lake) with healthy native plants filters incoming runoff that all properties have and supports a vibrant lake wildlife scene. Frogs, turtles, minnows and fish all need safe respites, particularly for early growth. Friends of Beaver Lake received generous support for the planting project from residents whose shorelines were planted. Future shoreline planting projects will be considered based on he success of the test plantings and resident interest.
