Metadata Record Dublin Core Standard Title: Watershed Assessment 1:24,000 Hydrography Catalog Name: California Department of Forestry and Fire Protection OID: 667 CITATION INFORMATION Identifier: wahydro Title: Watershed Assessment 1:24,000 Hydrography Originator: California Department of Forestry and Fire Protection & USFS Publication Date: 2001 Information Resource Type Format: Computer file Content: Geographic information system Scale: 1:24,000 Other Citation Details: Data is provided in Albers Equal Area, NAD27, or in UTM, NAD27. IDENTIFICATION INFORMATION Abstract: Developed by Watershed Assessment Program, in cooperation with the USDA Forest Service Remote Sensing Lab. Includes separate linear and polygon layers. The procedures were based on BLM's Oregon/ Washington Hydrography Handbook using the LLID routing approach. The base linework is from 1:24,000 Forest Service Cartographic Feature Files (CFFs) and 1:24,000 USGS DLG-3 files. The original files were edited and new linework added. This dataset has been modified for hydrologic modeling in a stream network. Source files by 7.5' quadrangle were edge matched and edited for connectivity. The stream network has been centerlined through waterbodies using artificial connectors. All arcs have been connected and oriented to flow downstream, and are routed. Lat/long identifiers (LLID) are used to uniquely identify the stream routes, and are available in the route attribute table. Available for download by river basin, or CD-ROM including roads and DEMs. Browse Graphic URL: http://frap.cdf.ca.gov/data/browsegraphic/wahydro.gif Purpose: Provides seamless enhanced hydrography data by river basin, modified for hydrologic modeling. Supplemental Info: BLM's Oregon/Washington Hydrography Handbook can be viewed at http://www.or.blm.gov/docs/hydbook_2.pdf. Documentation for DLG hydrography is contained in "Digital Line Graphs From 1:24,000-Scale Maps. Data Users Guide 2, 1985", from the U.S. Dept. of the Interior, U.S. Geological Survey, Reston, Va.

DATA QUALITY ASSESSMENT: A quad by quad assesment of USGS topographic maps has been completed in order to verify that stream names match USGS stream names. We also checked to make sure we captured all the named streams off of the maps. All named routes with a frequency greater than 1 have been verified against the USGS topographic maps. //////////////////////////////////////////////////////////////////// FEATURE TYPE: line DATABASE FIELDS: INPUT OUTPUT DECI FIELD NAME WIDTH WIDTH TYPE MALS DESCRIPTION ---------- ----- ------ ---- ---- ---------------------- FNODE# 4 6 B - ID# of the beginning node (From NODE) of the arc TNODE# 4 6 B - ID# of the end node (To NODE) of the arc LPOLY# 4 5 B - ID# of polygon left of this arc (facing direction of the TNODE) RPOLY# 4 5 B - ID# of polygon right of this arc (facing direction of the TNODE) LENGTH 8 18 F 5 Length of arc (meters) NCWAP_HYD# 4 5 B - ArcInfo-assigned unique arc ID# NCWAP_HYD-ID 4 5 B - User-assigned arc ID# STREAMNAME 66 66 C - Official name of the stream (from USGS quad map or Geographic Names Information System STREAMLINK 15 15 C - Unique link item for each arc, for relating to other databases LPOLYLINK 15 15 C - Unique link item for relating an arc to a polygon in the Lakes layer SPATIALSOURCE 3 3 C - Original data source of the arc FVDATE 8 8 D - Field verification date, used to track ground-truthing EPAREACHNO 17 17 C - EPA Reach#, used to link to other agency databases STREAMORDER 2 2 I - Stream order, by Stahler method WTRBODYTYPE 2 2 C - Water body type HYDFLOW 2 2 C - Stream flow classification for SPACE and TIME PLANFLOW 1 1 C - Plan Flow for habitat identification SPECIES_CODE 14 14 C - Individual fish species codes FISHBEARING 3 3 C - Actual or modeled fish presence SPATIALEDIT 3 3 C - Spatial edit technique LSTREAMNAME 30 30 C - Local stream name *** The following fields are currently not populated, but are included to match the Oregon/Washington BLM standard *** FPADIST 4 4 I - Forest Practices Act buffer distance (meters) on private lands FEDDIST 4 4 I - Federal Buffer Distance (meters) for actual Riparian Reserve.
