Caption: This temperature graph shows minimum, maximum, and average water temperatures in North Fork Battle Creek at North Battle Creek Feeder Diversion Dam in 1996. 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 was ideal at this location for adult spring chinook holding (<61 F) and incubation of spring-run chinook eggs (<58 F) after September 15. Water temperatures at higher elevations tend to be more favorable to chinook salmon and this location is in the upper reach of the North Fork. See Info Links for more information on temperature thresholds.
