Rc51 thanks fer the info. I find it very helpful. I think I have a good buffer, a solid 150 yds of thick grass waterway that all my watershed dumps into before entering my inlet. The water slows down greatly while going thru the waterway to pond. Then I have a rip rap basin approx 8x10 of 4-8 in rip rap just before my inlet. There are lots of new young bullfrogs in the pond and I am seeing a small assortment of different water insects in the pond. I am about to take pics fee you guys to really see my scenario be back shortly!
