Data was compiled to provide a singular visual representation of conveyance waterways and features available to deliver water to CVPIA wetland habitat area and to which delivery points. The data is intended to be used to evaluate whether potential new sources of refuge water supplies can utilize existing conveyance waterways and facilities. Delivery points are considered by the U.S. Bureau of Reclamation’s Refuge Water Supply Program as the boundary of wetland habitat areas as described by section 3406(d) of the CVPIA.- The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system.
