I thank you for the reply & helpful info. here is another part of the situation that is also probably contributing to the clear water I now have. I replaced the spillway as the depth had fallen to less than 4ft for the last 3yrs. there had been grsses & weeds all grown up all over the steep banks of the dam. I mowed off the grasses & filled the pond back up to over 15 ft. The grasses & weeds that were on the babks are now all underwater & have tons of the algae all over them same as the hay bales do. The darn stuff is growing everywhere but the water is crystal clear & keeps getting even clearer . I have not had much ice or snow cover all winter,just for very short periods & it melts away.I am also getting huge globs of Milfoil blown by the wind on the edges of the pond.I use a rake & remove all I can 2 or 3 times a week.I think I now have several hundred lbs. of it in piles near the banks just from raking it out.
