Caption: This chart shows the percent of days in June through September where average temperature exceeded 22.5°C for each site in the Sheepscot River watershed with available data in the years 1994-2003. Sites are grouped by stream and listed in upstream order. Tributaries are listed in the order they join their parent stream. The percent exceedance varied considerably by year at most sites. Percent exceedance was higher at mainstem Sheepscot and West Branch Sheepscot sites than in the smaller tributaries. Elliott (1991) found that juvenile Atlantic Salmon stop feeding when temperatures exceed 22.5°C. Temperature data were compiled by the Maine Atlantic Salmon Commission. See Chart Table for a key to sites and see Map for site locations. See Info Links for more information.
