WOW! Good information, Eric!
It's hard to quantify how much WP I took out. It more or less covered the entire shoreline except for a few bare pockets, and it was anywhere from a few feet out from shore in some spots to up to 20 feet out in other spots. There was quite a bit of FA along with the WP, even last summer. The FA is worse now, however, now that the primrose is gone.
I never thought that nutrients that had gone to the WP would now be used for even more FA, but that makes a lot of sense.
I think the extremely hard water, plus scores of dead tilapia, minus WP have created this mess.
