||Sediment: Fines <0.85 mm by GMA, 2001
||Caption: This chart shows percent fines <0.85mm from McNeil samples by Matthews and Associates at ten Big River sites. Matthews and Associates collected and processed the bulk gravel samples in 2001 using dry-sieve/gravimetric methods. The reference value shown represents an appropriate target (10.3%) for dry-sieve results based on adjustment methods of Shirazi and Seim (1979) and the EPA TMDL threshold for percent fines <0.85mm (14%). This reference value indicates that fine sediment may be a problem for salmonids in Two Log Creek, the Little North Fork, the East Branch of the North Fork Big River, and the South Fork Big River.
