Topic	Temperature: Floating Weekly Ave, Lower Two Log Creek, 1993-1995,98,01

 

Caption:  The maximum floating weekly average water temperature, or MWAT, in lower Two Log Creek (BIG4) exceeded the fully suitable range for salmonids in three of five years measured. The maximum floating weekly average temperature, or MWAT, exceeded the suitable range in 1993, 1995 and 1998. The 60 degree F (15.6 C) stress threshold for coho salmon was chosen as a threshold for the North Coast Watershed Assessment Program based on literature review. Floating weekly average water temperatures mask transient peaks and the 50-60 F reference from NCWAP would be more appropriately applied to maximum daily readings.
