Document Description
The project includes the modification of facilities at 197 sites located throughout the District's water conveyance system in Butte County, California. The Project involves mostly minor construction activities, including upgrades to measure deliveries at customer gravity deliveries and pumped deliveries. The District has received implementation funding through the California Department of Water Resources (DWR) and the U.S. Bureau of Reclamation, and the proposed actions are expected to be completed by mid-2021. Project activities will vary according to the needs of each specific improvement location. These activities typically will include upgrading existing customer delivery turnouts, upgrading canal headings to provide improved flow measurement, and installing real time monitoring equipment at primary operational spills. Structural improvements will consist of installing new turnout components including weir boxes with mounting plates, culverts and sluice gates, staff gages and stilling wells, and sharp-crested weirs at operational spills. At some locations construction activities will be limited to replacing existing aboveground equipment, but at other locations construction will result in ground disturbance during the removal and replacement of irrigation pipes, headwalls, and other structures.(See NOC for full details)
