I live on an approx. 2 acre pond that is owned by the HOA. This year we had a large growth of what I guess to be duckweed.

The weeds go from shore to about 6 feet out on average. The HOA had the pond treated on May 9th with "Captain". This week the weeds appeared to be dying and there was a noticeable bad smell.

My neighbor and I raked about 20 yards of shoreline to open a space for fishing. I don't mind doing this if it is worth the effort, would removing these weeds be preferable? Did the copper treatment kill them, or will that only kill algae? Will the weeds just decompose on their own eventually?

Is there any benefit to raking/agitating the dead debris on the bottom of the pond, will that help it break down if I keep at it?

Thanks!
