| Caption: This chart shows floating weekly maximum temperatures in the lower Dearborn Brook for the year 2001. Temperatures in Dearborn Brook were mostly within optimal range for Atlantic salmon. Maximum temperatures exceeded the optimal juvenile feeding range (19 C) on some days between June and September, but never exceeded 22.5 C, which is the point where fry and parr stop feeding. Average temperatures were rarely above optimal and minimum temperatures always fell back within optimal ranges. Seasonal fluctuation was 12.3 C between June and September with a maximum 4.9 C nocturnal/diurnal difference. Elliott (1991) found that juvenile Atlantic Salmon stop feeding when temperatures exceed 22.5 C. Temperature data are from the Maine Atlantic Salmon Commission.
