Sediment: Percent Fines <2 mm at Main Battle WA Sites 2001-2002 |
|
Caption: This chart shows surface fine sediment (<2 mm) from lower mainstem Battle Creek Watershed Assessment sites based on data collected in 2001-2002 with the EMDS reference value for "fully functional" salmonid habitat of less than 11%. Light blue bars signify that all sites are in response reaches. Site #004 was not sampled for fines. Fines increase in a downstream direction from site #054 to #032, which is corollary to the decreasing D50 values and suggests recent sediment supply, possibly from the January 1997 storm. Abbreviations are ds = downstream and ab = above. Data from Terraqua (2004). See Info Links for more information.
