MDNR Fishing Update for Oakland County Sportsmen's Club

Here is the presentation I had prepared. The information we collected was more about the habitat availability than the fish. Slide 6 (Looking at habitat availability) shows the water temperature profile on the left and the dissolved oxygen profile on the right. Each profile was collected in the deepest portion of the main basin, intended to identify the stratification zones (epilimnion, metalimnion, and hypolimnion) established throughout the water column along with the associated temperatures and dissolved oxygen levels. For both graphs, the water surface is at the top and going deeper as you proceed down the y-axis. Townsend lake had a similar temperature profile to the other lakes but was slightly cooler, even though it was only a few degrees of difference. The oxygen profiles do differ, with suitable oxygen through to about 26 ft of water and then quickly decreasing after that in Townsend Lake. For most species in Michigan, minimum suitable oxygen levels are typically about 3 mg/L (the red line). We three of the lakes go below that level before reaching the maximum depth where water temperatures are cold. Maceday Lake maintains high levels of dissolved oxygen pretty much through out the whole water column, even down to 100 ft. This is why Maceday Lake can support lake trout and splake, as well as cisco.

January 22, 2022 will be the OCSC’s second Stone Fly Search in conjunction with the Clinton River Watershed Council (CRWC). Stonefly larva are very sensitive to water conditions and finding them in the Clinton River Watershed helps biologist assess the quality and health of our local waters.  Stoneflies are most active in January and can often be seen on the snow near rivers and streams.  The larva live in the water for 1 to 3 years until they are mature and then emerge from the water as adults.

Last January I conducted our first winter stonefly search off the Clinton River dock here at OCSC. Unfortunately, I did not find any.  That doesn’t necessarily mean there are none...but the conditions were not optimal to find them.  As I recall, it was just me doing the search, it was about 10 degrees outside, and there was 2 to 3 inches of ice covering the river.  The entire CRWC Stonefly team did find  several in multiple locations on the Clinton River, so we know that the river is doing very well.

I am hopeful to have a few other volunteers to let our search cover more ground and maybe Mother Nature will have just a little less ice in the way.
