Zoom Major Northern California Reservoirs Main Menu Sacramento River T-C Canal Stony Creek Pipeline GCID Canal Delevan Pipeline (Will no longer be required for diversion of water into TC Canal) Physical Features Map Proposed Offstream Reservoir The map to the right is of the NODOS Features including Sites Reservoir and its conveyance facilities. There are five areas of interest that can be zoomed into for a closer view and more information. The five areas are:- The Tehama-Colusa Canal (T-C Canal)- The Glenn-Colusa Irrigation District Canal (GCID Canal)- Stony Creek Pipeline- Delevan Pipeline- Sites Reservoir FacilitiesClick on the blue highlighted boxes to zoom into that area of NODOS and learn more about that facility or Click the back button to return to the Northern California Map Lake Shasta Sacramento River Lake Oroville Zoom Zoom Sites Reservoir Folsom Lake Sacramento Sacramento-San Joaquin Delta Zoom Zoom ◄ Back
