Gualala River upstream of Highway 1 Bridge on April 10, 2002. The extremely wide gravel bar with very small median particle size distribution are indicative of a high and active bedload. Photo provided by Patrick Higgins.

This photo shows a zoom of the same area as shown in Picture #6, looking downstream off the Highway 1 Bridge on April 10, 2002 in the Gualala River estuary. Note how shallow the estuary is except immediately adjacent to bed rock, where scour mobilizes sediment and creates a deeper area. High sediment is likely restricting carrying capacity for juvenile steelhead in the Gualala estuary and lagoon (after the mouth closes, see Picture 8). Photo provided by Patrick Higgins.
