Stream Gage Installation on Elk River, Jalama Creek, Salinas River, South Fork Trinity River, and White River Bridges

The California Department of Water Resources (DWR) is overseeing a project to install stream gages at five bridge locations across Humboldt, Santa Barbara, San Luis Obispo, Trinity, and Tulare counties. The installation sites include the Elk River, Jalama Creek, Salinas River, South Fork Trinity River, and White River bridges. The United States Geological Survey (USGS) is responsible for the installation of the equipment, while DWR will handle subsequent operation and maintenance. The installed systems will consist of stage sensors, antennas, solar panels, batteries, cables, wire-weight reference gages, and NEMA boxes mounted to bridge guard rails or decks, with water temperature sensors placed streamside and connected via steel conduit. The project is classified as a forecast with a NAICS code of 237310 and is managed by Senior Environmental Scientist Amy Lyons. It has been granted categorical exemptions under California Environmental Quality Act sections 15304 and 15306 due to its negligible environmental impact. The primary objective is to establish five fully operational systems capable of long-term, unattended operation to provide real-time hydrologic and temperature data. No specific contract value, formal period of performance, or federal FAR clauses have been identified in the provided documentation.
