Thermograph: SYRCL LY Daily Temperature Hammon Grove Top Backwater 2009

Chart Caption: 
Water temperature in the Lower Yuba River Hammon Grove Top Backwater remained cool throughout the period of record in 2009, and the daily average temperature did not exceed lethal levels. This temperature logger became exposed to air on September 1 when the lower Yuba River precipitously decreased in flow following the end of the summer water transfer period. The threshold for temperature lethality comes from the report: Upper Yuba River Watershed Temperature Criteria for Chinook Salmon and Steelhead (Stillwater Sciences, 2006).
