American River Watershed Investigation, California. Reconnaisance Report
Abstract
This reconnaissance report has been prepared by the Sacramento District Corps of Engineers in accordance with the 1987 Appropriations Act. The report describes studies of alternative measures for flood control in the American River Watershed predicated on the assumption that Auburn Dam as previously authorized will not be constructed. Studies have focused on (1) definition of flood problems in the watershed, (2) formulation and evaluation of alternative plans for detailed development in future feasibility studies, (3) development of a management plan for the feasibility studies, and (4) identification of a non-federal sponsor for the feasibility study. The primary study area included the lower American River between Nimbus Dam and the Sacramento River and the Natomas area and vicinity of Sacramento. Other areas considered were the American River and its tributaries upstream from Nimbus Dam, Sacramento River from the American River upstream to the Sacramento Weir, and Yolo Bypass and its immediate tributaries and distributaries. Major flood control facilities and features in the study area are 400,000 acre-feet (ac-ft) of seasonally dedicated space in Folsom Reservoir, located about 25 miles east of Sacramento, and a complex system of levee and channel improvements downstream along the American and Sacramento Rivers and in the Yolo Bypass.
