A three-year project was conducted to determine methods of preventing and correcting erosion problems. Two-project sites were chosen in the vicinity of the Lake Tahoe basin in California. At both project sites, extensive hydrologic and water quality monitoring programs were conducted to determine erosion rates and their impact upon aquatic ecosystems. Monitored parameters included precipitation, snow depth, stream flow, suspended sediment and concentration, and benthic macroinvertebrate communities. Postdevelopment erosion rates at one site are estimated to be 100 percent above pre-develoment levels, resulting in only minor perturbations of the benthic macroinvertebrate community of West Martis Creek. Postdevelopment erosion rates within the second site are estimated to be over 10,000 percent above predevelopment levels, resulting in up to 99 percent destruction of the benthic macroinvertebrate community in Lonely Gulch Creek. At both project sites, extensive demonstrations were made of predevelopment planning concepts, construction techniques, and corrective measures which may be used to substantially reduce erosion and sedimentation problems associated with developments which are typical to the subalpine to alpine Lake Tahoe region of California. Analyses were made to determine cost and effectiveness of the various erosion control techniques which were demostrated at the project sites.
