Ice is off the entire lake as of Sunday March 29, 2021.
On April 19 the Dissolved Oxygen is 4.9 per Alex H.
The top of the pole the water guage is on has finally reappeared. There is alot of water in Shaver's.
Water Level 4.17 betweeen 210 and 220 .15? can't read the scale from the dock or a binoculars?
4/16 What was the LMCD baseline.
-------------------------------------------------
April 14, cattail bog breaks loose over between reeds and jensens and goes all the way down to henry/stickers. about 5 feet around. floating with the wind.

Dark Ice versus Light Ice
Late Fall / Early Winter Tips for Skating Ice
Now is the time to clear surface and down about 6 inches from any organic weed matter. Then when the ice forms you can have great looking and skating ice depending upon the weather than creates the ice.
We have a Jensen Lake Weed Mower for residents to use, call for details.
Methane Gas - The Lake Produces Lots Of It
So whats the difference between a swamp and a reservoir?
Did you know Shaver's is a source of methane production?
What happens to phosphorous/nutrients/organic matter that becomes sediment that compost under water in the absence of oxygen. (Hope that was said correctly)
Excess organic matter creates toxic fish kills in the winter.
Please read the attached article on Methane.
Here's what the DNR says about chemical cattail control:

Hi Cob, Actually late summer early fall (before the first frost) is the best time to control cattails with herbicide. At this time of year the plant is storing carbohydrate in the roots so herbicide is more readily translocated to the roots and kills the entire plant not just the leaves and stems, and by injuring the plant at this time of year you reduce its ability to survive over winter. You are correct the dead plant remains behind but it should not grow back in spring and if you were to remove the vegetation standing above the surface of the water (depriving the plants of oxygen over the winter months), and get an increase in water levels that would cover the cut stems you can further enhance the control of the cattails. At least those are the working theories on cattail control with herbicide. Hope this helps.
