Would getting rid of the various lawns at houses and apartments around the lake help reduce the blooms? Seems like they get worse every year, even though the duck/bird population seems smaller.
Perhaps it needs to be drained, filled with dirt and covered over. This way we can stop wasting time and money on it and remove a hazard.
