| Topic | Sediment: Less than 6.4 mm at Various Scott Basin Locations 1990 |
| Caption: The amount of fine sediment <6.4 mm was measured at 11 locations on the Scott River and at six sites within tributary basins by Dr. Sari Sommerstrom (1990). Mainstem locations are denoted by land ownership at the time of the study and go from downstream at left to upstream at right. Many locations had high levels of sand sized fine sediment. The threshold of 30% fine sediment (<6.4 mm) is derived from TMDL studies of coastal California rivers (see Info Links). Decomposed granite sands are a recognized problem in the Scott Valley and can decrease the quality of salmon spawning areas. See Info Links for more information. | |
