Maybe I should make another post in a different category but I figure I would put it here since all of my information about the pond is already posted on this thread. Today i foumd 2 dead bluegill floating. The first i have had in the 2 years i have had the property.My first assumption was dissolved oxygen I was already informed of it being low in the spring when I had it tested and yesterday I installed 3 aeration diffusers. I added one large bass from a nearby lake a couple of weeks ago but there has been no issues since then to lead me to believe but that is the reason. I also just added a sand beach. I laid down 6 mil plastic on the bank and continued it about 20 foot into the water. Then I covered the plastic with about 6 inches of river sand. When adding the sand to the water Brown bubbles appeared and have been floating around since then which has only been about 3 days. Also while I was spreading the sand I had a hydraulic line bust on a piece of equipment causing a very small amount of hydraulic fluid to get on the bank and sand and go into the pond worst case maybe a pint in the water. But by reading other posts on here about oil in the pond it seems that should not be an issue and it has disappeared by now.
