I managed to squeeze in a good look of these areas this afternoon before thunder sent me home. I will try to finish the job tomorrow.
Do we call call the slimy brownish green stuff that grows on most submerged rocks and logs “algae“ or is there another more specific name for it?
This stuff:
Gitch ... I went over to look and it is all filamentous algae. Sits on the bottom, hangs onto the plant stalks and, most importantly, when you take it up with a stick or your hand it hangs off in a slimy and stringy way. The cyanobacteria will be elusive and be just impossible to "hold" with your fingers.
Gitch ! Give us a grid number so that we have your finding on record! And we can also go out to look at that together. Post the info please
