Title

Seven Stream Gauge Installation Project

Description

DWR proposes to install seven new stream gauge stations providing a service to State, federal, and local agencies and private entities by monitoring water flow and quality in rivers, streams, and sloughs within the San Joaquin Valley. Stream gauge data is posted on the World Wide Web through the California Data Exchange Center (CDEC) and the Water Data Library (WDL), where it is accessible to the general public. Public and private entities rely on this data for a variety of applications. Six of the new stream gauge stations will be placed on the bank for stability and accessibility. Installation will require using a weed eater to clear weeds from each station site as needed. Each station box will be placed on an existing structure or placed on two station legs that will involve digging two 18-inch diameter by 36-inch deep bore holes with a hand auger. These holes will then be filled with concrete to support the two station legs. A cement slab, up to 4 feet by 4 feet, will be poured around the station legs. Up to four staff gauges will be installed in the streambed/bank at each location. Each staff gauge includes digging an 18-inch diameter by 2-feet deep hole with an auger in the streambed/bank, which will be filled with concrete to support galvanized steel pipe to hold each staff gauge. Approximately 250 feet of galvanized steel pipe (to contain the bubbler line) will be placed above ground and fastened to the stream bank with 3/8-inch rebar anchors. The stream gauge at Poso Creek will use an existing station that is connected to the downstream side of the Round Mountain Road bridge. One hundred and fifty feet of galvanized steel pipe will be fastened to the bridge running to the left bank and along the stream bank to the stream bed.
