Cecil, your observation that high winds were enough to cause clay to go into suspension is interesting--were you able to see any erosion around the banks? RBC, I'd read that once the stuff is in suspension it physically can't settle out; I wonder if what you had was just enough constant disturbance from fish, etc. that it stayed murky, rather than ever clearing; I do know that the reaction to addition of alum in our pond was quite striking! (And Cecil, thanks again for guiding me through that a couple of years ago on farmponds.com--ever in your debt).
