Here's a question (water/fishing related)...

[Phil Yearout]

I posted a while back about one of my favorite fishing holes being mossed over, and the consensus was: filamentous algae. I've checked on the lake a time or two since, and the result was the same; today I decided to give it a look, and viola: clear! I'd be surprised if anyone took it upon themselves to treat it but I could be wrong. We've had some major rain lately resulting in high water; the evidence of that was plain - sheets of the stiff on the surrounding vegetation, now dried from the sun. So my question: does water ever clear itself of this stuff, or did the high water do it, or...?

Filamentous algae grows due to excess nutrients in the water. So a lot of rain and a good deal of outflow from the pond could have reduced the nutrient level to where it isn’t growing any longer or at least until nutrient levels build up again

Clear water that allows sunlight to reach the bottom is a necessity for filamentous algae to grow. Dark water or water muddied from heavy rain runoff will kill it temporarily, but when it clears up again it will regrow.

I have fought it in my three ponds/lakes for a lifetime. Herbicides help for a few months but will never totally get rid of it. My grandad believed in fertilizing his pond with a special granular pond fertilizer to make the water dark. It would get so black in a few days after a fertilization that a paddle would disappear from sight in less than 12 inches depth. All algae would die and the water would be free of it for a month or so. When the water cleared back up the algae would come back.

Guess I'd better fish it while I can

Phil,

I'm not sure if you're at liberty to treat the water you're speaking of but this is what we use with great results.

Stan, sad thing is it worked and if your grandpap did that now the environazis would lock him up.
