Just a note: The 1-acre SMB/YP/GSH/RES/LCS pond has a watershed that is almost completely from a neighboring soy/maize rotated agricultural field. I credit the high water quality in the pond to the presence of a very small sediment pond and the use of GM crops to facilitate conservation tillage and use of environmentally friendly herbicides, plus the replacement of soil-applied and sprayed insecticides with in-crop Bt production. I have yet to see a dead fish in the pond. Hopefully, this will continue. Interestingly, my neighbor has also seen in big increase in his fur trapping which I account for by all the crop residue now available to herbivores all winter (rather than fall plowing as was common previously).
