Establishment of total maximum daily loads (TMDLs) in water-bodies is required under the Federal Clean Water Act to meet water quality criteria. Turbidity can be used as a surrogate for suspended sediment concentrations (SSC) to predict sediment load in streams. Real time in situ measurements of turbidity were collected at a stream gauging location in the Coast Range of Oregon from October 2005-June 2006 in conjunction with the collection of individual discrete water samples. The water samples were subsequently analyzed for SSC and turbidity in a laboratory.
