The California streams came from the Stephen P. Teale Data Center in Sacramento, CA. They were received in tiles that correspond to the USGS 1:250,000-scale for California. Edits to the original linework were made during the data conversion by Teale from the original DLG-3 format to the ARC/INFO GIS format. In 1992, the Teale hydrography data layer was sent to US EPA for use in their River Reach File system, version 3.roads are based on the USGS DLG transportation linework derived from the DLG-3 digital series. The California coverage was derived from the Stephen P. Teale Data Center, Sacramento, CA. The Oregon coverage was downloaded by hydrologic unit from the U.S. Geological Service. Less information is available concerning the lineage of the Oregon hydrography than is available for California. VITAL STATISTICS: Standard Teale Parameters?

Item was created for EPA's Reach File System. Use HSCKEY to connect to the Stream Reach Table (DS2) within a tile (see HYSNUM below). HYSNUM: Hydrography quad tile sequence number; 1 through 33. Item was created for EPA's Reach File System; combine with HSCKEY to uniquely code features across tiles. RF3RCHID: Primary key of RF3; concatenates CU, SEG, MILE; MAJOR1: Represents category to which each line data MINOR element belongs. Under each category, each attribute is identified by a separate code which denotes the specific nature of the element. Attribute codes and their description follow: Major Minor Code # Code # Element Description ------ ------ ------------------- 50 100 Alkali flat 50 101 Reservoir 50 102 Covered reservoir 50 103 Glacier or permanent snowfield 50 104 Salt evaporator 50 105 Inundation area 50 106 Fish hatchery or farm 50 107 Industrial water impoundment 50 108 Area to be submerged 50 109 Sewage disposal pond/filtration bed 50 110 Tailings pond 50 111 Marsh, wetland,swamp,bog 50 112 Mangrove area 50 113 Rice Field 50 114 Cranberry bog 50 115 Flats(tidal,mud,sand,gravel) 50 116 Bays,estuaries,gulfs,oceans,seas 50 117 Shoal 50 118 Soda evaporator 50 119 Duck pond 50 200 Shoreline 50 201 Man-made shoreline 50 202 Closure line 50 203 Indefinite shoreline 50 204 Apparent Limit 50 205 Outline of a Carolina bay 50 206 Danger curve 50 400 Rapids 50 401 Falls 50 402 Gravel pit/quarry filled w/water 50 403 Gaging station 50 404 Pumping station 50 405 Water intake 50 406 Dam or weir 50 407 Canal lock or sluice gate 50 408 Spillway 50 409 Gate(flood,tidal,head,check) 50 410 Rock 50 411 Crevasse 50 412 Stream 50 413 Braided stream 50 414 Ditch or canal 50 415 Aqueduct 50 416 Flume 50 417 Penstock 50 418 Siphon 50 419 Channel in water area 50 420 Wash or ephemeral drain 50 421 Lake or pond 50 422 Coral reef 50 423 Sand in open water 50 424 Spoil area 50 425 Fish ladders 50 601 Underground 50 602 Overpassing 50 603 Elevated 50 604 Tunnel 50 605 Right bank 50 606 Left bank 50 607 Under construction 50 608 Salt 50 609 Unsurveyed 50 610 Intermittent 50 611 Abandoned or discontinued 50 612 Submerged or sunken 50 613 Wooded 50 614 Dry 50 615 Mineral or hot (sulphur,alkali,etc.) 50 616 Navigable transportation 50 617 Underpassing 50 618 Earthen construction 50 000 Photorevised feature Data Quality Assessment: California data: The USGS DLG features of this layer are fairly complete. The density of line work varies from quad to quad; there arestreams that disappear at the edge of 100k quads. The geographic feature accuracy is fair. Contiguous features are not always matched across map sheet boundaries. The attribute completeness and accuracy is good. Oregon data: The revisions to the Oregon linework are a little behind California. Modifications were made to the entire coverage to match the attributes for both states without destroying links to the California .DS2/.DS3 tables. Stream names are present for about 1/3 of the entire coverage.
