Sediment: Median Particle Size (D50) at NF & SF Digger Battle WA Sites |
|
Caption: This chart shows the median particle size (D50) from pebble counts at samples sites along the North Fork and South Fork Digger Creek measured as part of the Battle Creek Watershed Assessment. The reference lines on the chart are the EMDS model limits for D50 that represent optimal particle size ranges for salmonids. Although the South Fork above the A-Line Road was partially functional according to EMDS criteria, most sites were well outside that range. Most sites are in transport reaches (dark blue) where stream energy is high. Abbreviations are ds = downstream and ab = above. Data from Terraqua (2004). See Info Links for more information.
