Not sure where to start on this...

Friend has a ~1 acre pond that has bass, perch and maybe some catfish left. However, the bass have started to die and float to the surface. With the current drought the deepest part of the pond is 5ft. Seems really odd that a lot of bass died all about the same size. No perch, minnows or anything else has died at this time. I thought maybe low oxygen level during the summer but its cooler weather now.

One thing my friend noticed is a slime like algae growing over the grass and good algae. Says he has never seen it before.
