Twenty-one of 37 sampling sites tested were in violation of Vermont's water quality standard of 77 colonies per 100 milliliters of water.  The bacterial pollution developed as water levels in the low river were sharply increased by heavy rain causing a low and rising (LR) flow condition.  Flow readings at the USGS gage in Moretown (http://waterdata.usgs.gov/nwis/uv/?&site_no=04288000) increased from a low of 34 cubic feet per second on Saturday, July 7, to a high of 158 cubic feet per second recorded on Monday, July 9, at the time of the Mad River Watch sampling.  

With an increase in water flow like this, there is always a possibility of higher E. coli counts as bacteria is flushed into the brooks and streams and into the main stem of the Mad River.

"In most circumstances E. coli levels will begin to come back down until another rain event starts the cycle over, and it does look like we could get several more thunderstorms over the course of the next week. Swimmers should check the local weather forecasts before heading out to their favorite swimming hole. Our next testing date is July 23," said Friends of the Mad River watershed coordinator Miranda Lascaze.
