Site History and Remarks

The Muddy River channel was covered on May 18, 1980 with massive sediment deposits from debris flows and mudflows, and sediment loads are contributed by erosion of the deposits and by bank failures of older, exposed alluvium. Vertical-profile data were collected from the cableway at the gaging station cross-section. (Dinehart, 1987)

Station originally established at bridge upstream on August 1, 1980, moved to present site on December 19, 1980. (Dinehart, 1981)

Reach Description

The sand-bed channel is confined in a narrow reach having bedrock banks that support a dense forest. (Dinehart, 1987)
