The chart shows maximum daily water temperatures during summer of 1997 of the Mainstem Salmon River above, below and in Crapo Creek. Mainstem temperatures were critical in this reach from early July through mid September. Notice that although temperatures in Crapo Creek were considerably lower than in the Mainstem, Crapo Creek seemed to have little cooling influence on the Mainstem. Data gaps exist because the temperature sensor below Crapo Creek was out of the water for a short period of time. Unit was repositioned on July 17th and accurate data collection was resumed. This chart was derived from Chart Table MSMax97.dbf, which was derived from Source Table SAMS97.dbf. The data for the Source Table was taken from automated temperature sensors called Hobotemps, which were anchored in flowing water in the shade, recording temperatures between June 5 and September 30, 1997. Hobotemps were monitored by students at Forks of Salmon School and paid staff of the Salmon River Restoration Council.
