I also have a natural fertilizer in nutrient overflow from my trout pond to my warm water pond and all the fish I feed in the warmwater pond. Seechi dish reading stays between 12 and 36 inches for the most part in summer.

Last year after I harvested about 100 lbs. of bass between 2 to 4 lbs. the water gradually cleared up to gin clear later in the fall. And I'm sure shutting down the trout pond flow had an effect.

I know phytoplankton decreases in colder water, and of course species change dominance. But this was obviously related to the reduction of the fish in the pond. Large blooms of filamentous algae blossomed on the bottom although it never floated up. Must not be a typical species of filamentous algae.

Ironically the pond phytoplankton has started to green up again under the ice and it is not as clear as it was before winter. Hopefully I will get my phytoplankton bloom back as I believe that has a lot to do with the size and rapid growth of some of the fish in the pond.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
