Caption:  Percent sediment less than 6.4 mm from McNeil samples in Little Bear Haven Creek (CFT 6) in the Middle Fork Ten Mile River are displayed above for the years 1993 to 2000. Two stations (riffles) in a study reach were sampled annually. Bars represent the average of four McNeil samples at a station and whiskers represent standard deviation and 95% confidence intervals. Sand and small gravel (<6.4 mm) were over levels known to impair salmonid survival in several years, including the range of all samples in 1994-1996 and 1999-2000. Reference line is from Kondolf (2000) who reported 30% <6.4 mm corresponding to 50% emergence of salmonids. The 6.4 mm results shown here were interpolated from 4 mm and 8 mm data provided by Hawthorne Timber Company. See Info Links for more information.
