Caption: This chart shows the maximum daily water temperatures during summer of 1998 on the SF Salmon River above, below and in Methodist Creek. Notice that Methodist Creek was actually warmer than the SF Salmon until late July, when it became noticeably cooler during the hottest part of the summer. Methodist Creek seemed to have little cooling influence on the SF Salmon during the peak summer temperatures. The confluence was a refugia for Salmonids when temperatures in the river exceeded stressful levels. Data were collected from automated temperature sensors called Hobotemps, which were anchored in flowing water in the shade. Hobotemps were monitored by community volunteers and paid staff of the Salmon River Restoration Council. Click on Picture* to see recent historical data and photographs of Hobotemp sites.
