Sediment and stream velocity data from the Sacramento River are required to determine the size requirements of a settling basin for the intake area of the proposed Peripheral Canal near Hood, California. Sediment and stream-velocity data were gathered from May 1978 to September 1981 over several magnitudes of streamflow at four cross sections near Hood. This report, prepared in cooperation with the California Department of Water Resources, contains data that show the vertical distribution and size of sediment, and the magnitude and direction of stream velocity measured at 25 points in each of the four cross sections on several occasions.
