And in five years became semi-clean and in about 12 years could support stocked trout and continued to improve after that. But I could also include Little Sugar Creek and it 's recuperation after sewage improvements in a couple of cities that drain into it. What was the major pollution in the James? Nutrients, primarily Phosphorus from wastewater discharges. Springfield being the big one. BIG algae blooms before SGF put in nutrient removal. All discharges to Table Rock lake now have P limits, and the larger ones also have Nitrogen limitations. You are right about MDNR getting that credit. They're the water quality protection agency, Johnsfolly, snagged in outlet 3 and tjm 1 2
tjm Posted January 27 Posted January 27 Phosphorus limitations are good and bad, too little P is the sole cause of the "rock snot" Didymo bloom.
