Sediment: Redwood Creek Fines <0.841mm 1994 & 1995 |
|
Caption: This chart shows the mean levels of percent fine sediment less than 0.841mm measured at three stations in Redwood Creek in the years 1994 and 1995. Whiskers represent one standard error. These data were collected by University of San Francisco (USF) for the Golden Gate National Recreation Area. USF notes, from various sources, the upper limits of fine sediment associated with successful spawning. Station 1 was located near headwaters, Station 2 at Muir Woods Road mile 1.96, and Station 3 at Muir Beach parking lot. The lower gradient of Redwood Creek near Station 3 explains the accumulation of finer particles there.
