BIDWELL CREEK NEAR FORT BIDWELL STREAM GAGE INSTALLATION PROJECT

The County of Modoc, through funding provided by the California Department of Water Resources Stream Gage Improvement Program (CalSIP), proposes installation of a stream gage and associated monitoring equipment to reestablish streamflow monitoring capabilities at a historically monitored location on Bidwell Creek near Fort Bidwell. Project improvements include installation of a solar-powered datalogger control box equipped with telemetry equipment, an antenna, and solar panel, approximately 300 feet upslope of the left (north) bank of Bidwell Creek. The control box will be supported by two posts installed in approximately 2-foot-deep, 6-inch-diameter augured holes and secured with concrete footings. A flexible 2-inch PVC conduit will extend from the control box to a gaging pool within the stream channel where a bubbler gage will be installed. The conduit and bubbler assembly will be secured using J-hook rebar anchors placed on the ground surface to maintain stability. Installation of the bubbler gage and conduit will not require excavation, dredging, streambank modification, or removal of material from the streambed. A tagline across Bidwell Creek will be installed to facilitate streamflow measurements and equipment maintenance. Tagline support will either be attached to existing trees or posts installed on each streambank using approximately 2-foot-deep by 6-inch-diameter augured holes backfilled with concrete. The project is intended to provide reliable, real-time streamflow data for water resource management, public safety, water supply planning, and conservation of freshwater resources.
