Document Description
The Proposed Project is located in Amador County approximately 24 miles northeast of Jackson. Construction will take place at the Tiger Creek Regulator Dam and Reservoir on Tiger Creek. The Proposed Project includes a new spillway along the Dam’s right abutment and abandoning-in-place the old spillway infrastructure along the Dam’s left abutment. The purpose of the Proposed Project is to update the Dam to safely pass a flood event of up to 6,000 cubic feet per second. New spillway construction includes: a new spillway intake (crest structure), new notch through the existing dam, new concrete chute, new flip bucket splitter blocks, and new plunge pool. Other associated features of the Proposed Project include a permanent access road to the new spillway, a temporary construction access road with four temporary bridges across Tiger Creek, a temporary 240-foot-long cofferdam in the Reservoir to facilitate new spillway construction, a new 450-foot single span log boom and anchor blocks, new lighting on the Dam, and three staging areas. The IS/MND is being recirculated because on May 9, 2024, PG&E revised the Proposed Project description to move the concrete batch plant from the Cedar Mill staging area to the Spur 1 staging area.
