Document Description
As part of the California Stream Gage Improvement Program (CalSIP), the Corning Sub-basin Groundwater Sustainability Agency (CSGSA) is proposing to reactivate a stream gage along Stony Creek. The stream gage will monitor streamflow and water levels to inform water resource planning and management. An image-velocimetry camera will be installed at the location where the Glenn-Colusa Canal siphons under Stony Creek (39.710806, -122.007444). Installation will include placing a mast post with concrete footings and attaching an image-velocimetry camera, solar panel, radio antenna, and steel RTU enclosure to the mast post. A bubbler line will be routed from the RTU enclosure to the toe of the stream channel using existing two-inch conduit. A sloped staff gage will be installed and grouted into the surrounding riprap. The steel RTU enclosure will house a data logger, battery, and radio equipment. See the attached project description for a detailed description of the proposed activities.
