Description
A characterization of the data, including its intended use and limitations.
Abstract:
Hyd250 was created from the 1:100,000 scale hydrography. Certain outdated attributes in the coverage aat were removed. 

This generalize coverage came from the attribute seg. Arcs with seg numbers less than 500 were legacy arcs from the 1:250,000 scale hydrography. 

(description): The U.S. Geological Survey (USGS) in cooperation with Federal and state agencies, and NW Indian Tribes has produced a 1:100,000-scale River Reach data layer for the Pacific Northwest that will serve water-resource management applications for the next decade or more. The Pacific Northwest (PNW) River Reach Files are a geo-referenced river reach data layer encompasses the Columbia River Basin within the conterminous United States U.S. Environmental Protection Agency's (USEPA) reach codes. This encoding process was a primary task of the PNW River Reach Project. USEPA's reach identifiers are an integral hydrologic component in regional Rivers Study known as the Northwest Environmental Data Base(NED). NED is an ongoing effort by Federal and state agencies within the region to compile reach-specific information on rivers in Oregon, Idaho, Washington, Montana.
Purpose:
A unique conflation algorithm was developed by the USGS-WRD in Portland, that transferred the USEPA reach codes and other meaningful attributes from USEPA's 1:250,000-scale RF2 Files to the 1:100,000-scale hydrography. The new 1:100,000-scale PNW Reach Files were designed so reach-specific could be extracted from a stream network in an upstream or downstream direction using associated feature attribute tables or within a Geographic Information System. In Idaho, the Department of Water Resources uses these data in its basin planning efforts and the Department Fish & Game to map information in its Idaho River Information System (IRIS).
Supplemental information:
The data documented in this file are split up between stream centers (for networking applications) and water bodies, including lakes, ponds, reservoirs, and wide rivers. The data are tiled and distributed by Hydrologic Unit

Overview
Summary of the information content of the data, including other references to complete descriptions of entity types, attributes, and attribute values for the data.
Entity and attribute overview:
File Name: each data set's file name uses the following construct: an 's' (stream centers) or 'b' (banks) followed by the last seven digits of the eight-digit Hydrologic Unit Code (HUC) name (the first number, usually '1,' is dropped); for example, b7050114, is the banks coverage of HUC 17050114

Metadata Standards
Description of the metadata standard used to document the data and reference to any additional extended profiles to the standard used by the metadata producer.
Standard name: FGDC Content Standards for Digital Geospatial Metadata
Standard version: FGDC-STD-001-1998
Time convention: local time
Metadata profiles defining additional information:
Profile: ESRI Metadata Profile
FGDC Plus Metadata Stylesheet
Stylesheet: FGDC Plus Stylesheet
File name: FGDC Plus.xsl
Version: 2.3
Description: This metadata is displayed using the FGDC Plus Stylesheet, which is an XSL template that can be used with ArcGIS software to display metadata. It displays metadata elements defined in the Content Standard for Digital Geospatial Metadata (CSDGM) - aka FGDC Standard, the ESRI Profile of CSDGM, the Biological Data Profile of CSDGM, and the Shoreline Data Profile of CSDGM. CSDGM is the US Federal Metadata standard. The Federal Geographic Data Committee originally adopted the CSDGM in 1994 and revised it in 1998. According to Executive Order 12096 all Federal agencies are ordered to use this standard to document geospatial data created as of January, 1995. The standard is often referred to as the FGDC Metadata Standard and has been implemented beyond the federal level with State and local governments adopting the metadata standard as well. The Biological Data Profile broadens the application of the CSDGM so that it is more easily applied to biological data that are not explicitly geographic (laboratory results, field notes, specimen collections, research reports) but can be associated with a geographic location. Includes taxonomical vocabulary. The Shoreline Data Profile addresses variability in the definition and mapping of shorelines by providing a standardized set of terms and data elements required to support metadata for shoreline and coastal data sets. The FGDC Plus Stylesheet includes the Dublin Core Metadata Element Set. It supports W3C DOM compatible browsers such as IE7, IE6, Netscape 7, and Mozilla Firefox. It is in the public domain and may be freely used, modified, and redistributed. It is provided "AS-IS" without warranty or technical support.
Instructions: On the top of the page, click on the title of the dataset to toggle opening and closing of all metadata content sections or click section links listed horizontally below the title to open individual sections. Click on a section name (e.g. Description) to open and close section content. Within a section, click on a item name (Status, Key Words, etc.) to open and close individual content items. By default, the Citation information within the Description section is always open for display.
