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 on Bidwell Creek near Fort Bidwell. Project improvements include installation of a bubbler pressure-sensor stream gage and associated monitoring equipment. The Project includes installation of a solar-powered datalogger/control box with telemetry within an existing roadside turnout, supported by two posts installed in approximately six-inch-diameter holes approximately two feet deep; installation of conduit between the control box and the stream gage; installation of associated anchoring; and installation of low- and high-flow staff plates along the streambank. The Project will use hand tools and small equipment and will result in minimal ground disturbance, primarily associated with the two control-box postholes. The Project does not include grading, dredging, stream channel modification, substantial vegetation removal, alteration of the streambank or streambed, diversion or obstruction of streamflow, or placement of fill within the stream channel. The Project was originally proposed at a different location along Bidwell Creek. The original location was subsequently determined to be unsuitable for installation and operation of the stream gage, and the Project was relocated to the existing roadside turnout along County Road 224 described above. The environmental review and CEQA exemption determination are based on the revised Project location and Project description.
