This chart shows the maximum daily water temperatures during summer of 1997 of the SF Salmon River above, below and in Knownothing Creek. Notice that the water in Knownothing Creek was noticeably cooler than in the SF Salmon, and seemed to influence the water temperature of the SF Salmon below the confluence. This suggests that Knownothing Creek was large enough to noticeably influence the temperature of the SF Salmon. The mouth of Knownothing Creek also provided a cold water refugia for Salmonids during the summer temperature peak. This chart was derived from Chart Table KNMAX97.dbf, which was derived from Source Table Sakn97.dbf. Data for that table was collected by automated temperature sensors called Hobotemps, which were anchored in flowing water in the shade between June and September 1997. Hobotemps were monitored by students at Forks of Salmon School, community volunteers and paid staff of the Salmon River Restoration Council.

This chart shows the maximum daily water temperatures during the summer of 1998 of the SF Salmon River above, below and in Knownothing Creek. Notice that, starting in late July, Knownothing Creek was noticeably cooler than the SF Salmon. The cooler water temperature of Knownothing Creek, however, did not seem to significantly impact the temperature of the SF Salmon below the confluence. The mouth of Knownothing Creek provided a cold water refugia for Salmonids during the summer temperature peak. Data were collected by automated temperature sensors called Hobotemps, which were anchored in flowing water in the shade between June and November 98. Hobotemps were monitored by students at Forks of Salmon School, community volunteers and paid staff of the Salmon River Restoration Council.
