WLOA FALL HARVEATING REPORT 2015
There were 122 loads of weeds harvested from the lake this season:
*73 loads of weeds taken from Watkins Lake East
*49 loads from Watkins Lake West
The Composition of the weeds this year was about 50% Milfoil, and the remaining weeds were made up of Chara, Starry Stonewort and various kinds of Pondweeds.
This is the second year in a row where we have had very unusual lake environmental conditions. Last season we saw a bumper crop of Eurasian Milfoil, which lead us to hire a Limnologist, and this summer we have very little Eurasian Milfoil. I can only guess as to the reason for these two wildly different harvesting seasons. Here are some speculations that I have which might affect the biology of the lake:
* We harvested about 150 loads of Eurasian Milfoil from the lake last year and it is likely that we changed the growing conditions enough so that they did not reappear nearly as heavily this season.
* Cara and Starry Stonewort seem to be outcompeting Milfoil in areas that we used to have Milfoil
* The past two winters have been very cold and the ice has stayed frozen until late into the spring
Because of the sparse Milfoil crop this season we were able harvest in the bay areas and around docks more effectively. When we are harvesting Chara and Stonewort the loads will look smaller but are usually very heavy and dense which means we are removing biomass and nutrients from the lake. We can do this very selectively so that we don’t impact any one part of the lake in a negative manner.
We are in the process of winterizing the equipment and should be done by the end of the week.
There will be one more Claudia Park gate code change and I will send that out in late October.
