Document Description
DWR proposes installing two new stream gauge stations that provide a service to State, federal, 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 public. Public and private entities rely on this data for various applications.
Fresno River stream gauge will be placed on the bank for stability and accessibility. The station box will be placed on two station legs. The station legs will be installed within two 8-inch diameter by 36-inch-deep hand augured bore holes. These holes will 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. Each staff gauge includes digging an 18-inch diameter by 12-inch-deep hole with an auger in the dry 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 Chowchilla Bypass will use an existing station on the left bank connected to a concrete weir. The staff gauge will be mounted on the cement headwall. The bubbler will extend 20 feet into the channel.
