The Regulated Streams dataset was compiled from the High Resolution National Hydrography Dataset for California. The reaches included are based on Table 8.1 - Regulated Streams and Nonpermissible Work Periods found in Barclays California Code of Regulations. The High Resolution NHD is based on 1:24,000 topographic mapping. The start and endpoints of the Regulated Streams have been detemined, where possible, by the descriptions found in Table 8.1. Those reaches lacking specifically defined start and endpoints in Table 8.1 have been included in their entirety within each county specified in the \"County-Limits\" column of Table 8.1. All reaches described in this table were found in the NHD except for Globe Slough and Five-Mile Slough in Fresno County, Hughes Creek in Kings County, Moody Slough in Solano County, and Mud Slough Creek in Butte County. Additionally, the linework in this dataset representing Colusa Bypass and Moulton Bypass and Weir in Colusa County were not found in the NHD. These lines have been digitized from the lines on the 7.5' USGS topographic quadrangles. The linework representing Ida Island in Sacramento County was derived from gaps in the NHD polygon feature class representing Sacramento River in the vicinity of the island. The linework representing Yolo Bypass in Yolo and Solano counties is comprised of the High Resolution NHD polyline features contained within the California Levee Database (DFM_CALeveeDatabase_v22_R2_20110128_93.mdb) levee centerlines that define the boundaries of Yolo Bypass. The linework representing Sutter Bypass in Sutter County is also comprised of the NHD polyline features within the CLD levee centerlines that define the boundaries of Sutter Bypass. The linework representing Atherton Cove (northeast bank) in San Joaquin County is a segment of the levee centerline from the CLD.<\/SPAN><\/P>

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. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water bodies. Reaches are also defined on waterbodies and the approximate shorelines of the Great Lakes, the Atlantic and Pacific Oceans and the Gulf of Mexico. The NHD also incorporates the National Spatial Data Infrastructure framework criteria established by the Federal Geographic Data Committee.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "summary": "The Regulated Streams feature class is a subset of the High Resolution California National Hydrography Dataset (NHD) maintained by the United States Geological Survey (USGS).
