Document Description
The Relief Dam Low Level Outlet (LLO) and S-2 Weir Project consists of the installation of three new valves on Relief Dam, and the construction of a concrete weir approximately 100 feet downstream of Relief Dam. These new valves will allow for more accurate releases of water from the dam. The weir installation will allow the flows released from the dam to be measured accurately. The ability to accurately control and measure the flows out of Relief Dam will help to ensure that dam's operation requirements are met. These operation requirements contain measures designed to protect fish and wildlife downstream of the dam.
