KRIS Battle Creek: Chart Page

Area North Fork Battle
Topic Temperature: Min, Max, Avg at Wildcat Dam, 1995
Caption:  This temperature graph shows minimum, maximum, and average water temperatures in North Fork Battle Creek at Wildcat Diversion Dam in 1995. Thresholds shown on the graph above are for the egg life history stage before July 1 for winter chinook and after September 15 for spring chinook eggs and for holding adults spring chinook during summer. Average water temperature fell mostly within the optimal range (<58 F) for incubating eggs of winter-run chinook salmon. Stress for adult spring chinook begins when average water temperatures exceed 61 degrees F. This threshold was exceeded for only two days during the period of record. Increased flows related to restoration are calculated to further improve conditions for both winter run and spring run chinook in this reach. See Info Links for more information on temperature thresholds.
