Document Description
The project consists of minor access trail improvements to the gauging station, and the installation of a reinforced concrete slab in the bottom of the creek below the normal water level. A stream flow bypass system will be installed to route the stream flow around the gauging station area, so that a concrete slab can be placed and anchored in dry conditions. No uncured concrete will be allowed to contact surface waters. The work will be performed under a California Department of Fish and Game 1601 Agreement, a US Army Corps Nationwide permit, a #401 Water Quality Certification, a Tahoe National Forest Special Use Permit, which includes requirements for environmental protection. Authorization to proceed from the Federal Energy Regulatory Commission will be obtained prior to construction.
