    | 
   Caption:  The California Department of Fish and Game (CDFG) monitored dissolved oxygen (D.O.) at several sites established by Gwynne (1993) along the Shasta River in 1994. Average and minimum D.O. are displayed above for four locations. D.O. less than 5 milligrams per liter (mg/L) are stressful to salmonids.  These data shows similar trends to those described by North Coast Regional Water Quality Control Board staff in earlier years.  The lowest readings were still at Highway 3 (rm12.79) with no problems in D.O. displayed at County Road A-12 (rm 20.99).  Lows at Anderson Grade Road (rm 8) and Montague/Grenada Road (rm 15.17) did drop to stressful levels for salmonids. Click on Info Links for more information.
