Consideration of cumulative watershed effects (CWEs) has both political and physical aspects. Regardless of the practical usefulness of present methods of dealing with CWEs, the legal requirement to address them remains. Management of federal land is regulated by the National Environmental Policy…

Cumulative Watershed Effects (CWEs) may be additive or synergistic. Additive CWEs are the accumulation downstream of the effects of various activities. Their existence is inevitable. However, their magnitude is often difficult to measure. The amount of sediment, for example, has considerable…

Data from two watersheds in northern California were used to develop an interpretation of the erosion-hazard rating (EHR) of the Coast Forest District as amount of sedimentation. For the Caspar Creek Experimental Watershed (North Fork and South Fork), each EHR unit was estimated as equivalent to 0…

Sediment delivery was estimated for 13 tributary watersheds and the North Fork of Caspar Creek. The ratio of sediment to erosion averaged 16.4%, ranging from 1.0% to 89.7%. Because the data were so highly skewed their median is a better indicator of central tendency than their mean. The median…

The effects of multiple logging disturbances on peak flows and suspended sediment loads from second-growth redwood watersheds were approximately additive. Downstream increases were no greater than would be expected from the proportion of the area disturbed. Annual sediment load increases of from…

A preliminary progress report of the research on the stream ecology of Caspar Creek by Humboldt State College was submitted by Dr. John DeWitt in December,1965, (DeWitt 1965). Further analyses of data collected during the summer of 1965 allows a more complete report to be made at this time.…

Abstract - This annual study has been conducted, since 1987, on two coastal streams, in order to observe the different trend patterns of juvenile out migrations for coho salmon and steelhead-trout, figure 1. Analysis of the 1993 trapping season indicates, at Little River, a decrease of steelhead-…

As part of a brief study tour in California, I had the good fortune of spending a very pleasant day on the Caspar Creek watershed, ably guided by Peter Cafferata and Liz Keppeler. Amongst the many notable achievements of the Caspar Creek Study is its longevity. The study started in 1962 and has…
