No news from me about the warter status, but here us a good link about E. Coli
E.Coli

Note that presence of coliforms could be either toxic or benign types or indicate association of other pathogens. Either way, they would want to close usage. I dont know where the intake pipe is, but I doubt they would test the stream progressively higher to find where the contamination area is located. I imagine Trailcamp has needed a good flushing for a long time. Will the testers retest every day? Every week? Month? Not again until next season? You would think this recent test sample was not simply a random test in a high risk area, but part of ongoing public safety monitoring .

Coming off the High Trail to Agnew yesterday there were a lot of flowing streams..... and a lot of horse manure
