Good link. All heavy equipment operators near streams should be required to read and follow the recommendations. We had a similar problem in Cherokee Village Arkansas. Some city bureacrat decided a bridge was endangered by gravel, so in the dozers went all over, under, again, redoing, excavating, pushing, hauling, whatever. A wonderful lady active in SOS, (save our spring river) Ruth Reynolds, wrote the local paper repeatedly, and brought in the corps, and the Department of Environmental Quality. Stopped that fast.
Maybe if the national guard wasn't in Iraq, they could be inpectors for water quality.
