CDFW Biogeographic Data Section with CDFW Northern Region Data Management and GIS May 2016 vector digital data National Hydrography Dataset (NHD) high resolution NHDFlowline features for California were originally dissolved on common GNIS_ID or StreamLevel* attributes and routed from mouth to headwater in meters. The results are measured polyline features representing entire streams. Routes on these streams are measured upstream, i.e., the measure at the mouth of a stream is zero and at the upstream end the measure matches the total length of the stream feature. Using GIS tools, a user of this dataset can retrieve the distance in meters upstream from the mouth at any point along a stream feature.** CA_Streams_v3 Update Notes: This version includes over 200 stream modifications and additions resulting from requests for updating from CDFW staff and others***. New locator fields from the USGS Watershed Boundary Dataset (WBD) have been added for v3 to enhance user's ability to search for or extract subsets of California Streams by hydrologic area. *See the Source Citation section of this metadata for further information on NHD, WBD, NHDFlowline, GNIS_ID and StreamLevel. **See the Data Quality section of this metadata for further explanation of stream feature development. ***Some current NHD data has not yet been included in CA_Streams. The effort to synchronize CA_Streams with NHD is ongoing. To provide an alternative to the native NHD measuring system of percentage of distance along reach length with one that enhances the ability to examine distance relationships along entire stream courses.

Some NHDFlowline features as indicated in 'EditVersion' attributes as having been modified by DFW projects and programs prior to routing as streams, are planned to but have not yet been submitted to NHD. See 'EditNotes' attributes for descriptions of these edits or email this dataset's point contact for additional information. USGS National Hydrography Dataset page 18 (see online linkage below) http://nhd.usgs.gov/chapter1/chp1_data_users_guide.pdf USGS National Hydrography Dataset PGDbReleveler Version 2.2.1 Designed and developed by Horizon Systems Corporation under contract to the U.S. Environmental Protection Agency Office of Water - Office of Wetlands, Oceans, and Watersheds in cooperation with the U.S. Geological Survey. For more information please email info@horizon-system.com or Call (703) 471-0480. Purpose: PGDbReleveler is designed to recalculate the Streamlevel field in the NHDflowlineVAA table of an ESRI/NHD Personal GeoDatabase. Input: A valid ESRI/NHD Personal GeoDatabase with a logically correct NHDflow table. Output: A releveled ESRI/NHD Personal GeoDatabase. A cumulative log file (PGDbReleveler.log) is created/updated after each run with the results of the last relevel process. U.S. Geological Survey in cooperation with U.S. Environmental Protection Agency, USDA Forest Service, and other Federal, State and local partners Varies per feature 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. Addendum: Modifications made by DFG to NHD Flowlines (reaches) for the purpose of enabling/enhancing DFG programs and projects have been included in this feature class. A field named DFG_Edit has been added to the attribute table to provide a description of these modifications. Only records with an entry in DFG_Edit have been modified from the original NHDFlowline feature class, hence these modifications have not yet been submitted to NHD. http://nhd.usgs.gov/ or http://nhd.usgs.gov/chapter1/chp1_data_users_guide.pdf US Geological Survey Ongoing The Geographic Names Information System (GNIS), developed by the U.S. Geological Survey in cooperation with the U.S. Board on Geographic Names, contains information about physical and cultural geographic features in the United States and associated areas, both current and historical (not including roads and highways). The database holds the Federally recognized name of each feature and defines the location of the feature by state, county, USGS topographic map, and geographic coordinates. http://nhd.usgs.gov/gnis.html US Geological Survey Ongoing The Watershed Boundary Dataset (WBD) defines the areal extent of surface water drainage to a point, accounting for all land and surface areas. A hydrologic unit is a drainage area delineated to nest in a multi-level, hierarchical drainage system. Its boundaries are defined by hydrographic and topographic criteria that delineate an area of land upstream from a specific point on a river, stream or similar surface waters. A hydrologic unit can accept surface water directly from upstream drainage areas, and indirectly from associated surface areas such as remnant, non-contributing, and diversions to form a drainage area with single or multiple outlet points. Hydrologic units are only synonymous with classic watersheds when their boundaries include all the source area contributing surface water to a single defined outlet point. http://nhd.usgs.gov/wbd.html Vector Simple FALSE 0 TRUE TRUE coordinate pair 0.000680 0.000680 meters North American Datum of 1983 Geodetic Reference System 80 6378137.000000 298.257222 0.000100 Explicit elevation coordinate included with horizontal coordinates CA_Streams_v3 N/A ESRI Feature Class 0 OBJECTID Internal feature number.
