Welcome to PB ! Assume all is frozen now given the location. I would suggest as a first step do a survey yourself by small boat taking depth readings. If ice is safe and you have an auger you can do it now. You can use a weight and marked string. Take pics of the dam and vegetation. Looks like vegetation removal/reduction and muck removal is a needed step. What general approach to take is dependent on if there are fish and if you want to save them. Sometimes raising the water level is easier than muck removal.
No fish that I am aware of. Never was stalked in the last 50 years to my knowledge.
Normally Ice would be safe but in this case I may have beavers hanging out in there. They were last year I have to confirm. If they are there then I really don't want to be on the ice right now as if I make a mistep I could be going through the ice.
This location unfortunately is about an hour away and no one lives at the old homestead anymore. I'm in town but would like to move out there at some point in the next few years.
Raising the water level right now is what has me unsure. If I raise it to much it will break through on the left side of the map and overflow into a couple acres of grass land that I didn't want full of water. I could raise it a couple feet but its so thick in there its hard to tell how much I could raise it.
I figured aeration would at least start helping with the muck problem but from my understanding it won't do much until the ice is off.
