Description: In 1960, Federal and State agencies jointly started a long-term study of the effects of logging and road building on streamflow, sedimentation, aquatic habitat, and fish populations on two watersheds of Caspar Creek, in northern California. The experimental watersheds are the North and South Forks of the Creek. The data being collected consist of continuous streamflow measurements, suspended sediment measured at weirs, changes in sediment deposition in debris basins behind the weirs, and rainfall. Effects of roads built in summer 1967 were monitored between 1967 and 1971. This paper summarizes data from 10 years of streamflow calibration and 4 years of recording effects of road construction and use.

Key Words: PSW4351, Caspar Creek, bridge building, road construction, logging operations, environmental impact, streamflow, sedimentation, fish habitat, California
