Originator:

The original national hydrography dataset layer was developed as a coverage named NHDDUU by the U.S. Geological Survey in cooperation with U.S. Environmental Protection Agency. Rr_nhdduu.shp was created by Circuit Rider Productions, Inc. Rr_nhdduu represents a portion of the national hydrography dataset that describes the lakes of the Russian River basin. The polygon features were selected based on their spatial location within the extent of the Russian River basin. This metadata file incorporates information that is specific to this layer as well as information that is available in the original metadata file for the hydrography (nhd.meta). Portions of this metadata file that borrow text from nhd.meta are indicated in quotation marks.

Description:

Abstract: The NHDDUU coverage contains regions representing the domains of the digital update units from National Hydrography Data. "It is based initially on the content of the U.S. Geological Survey 1:100,000-scale Digital Line Graph (DLG) hydrography data, integrated with reach-related information from the U.S. Environmental Protection Agency Reach File Version 3.0 (RF3)."

Purpose:

"The National Hydrography Dataset combines elements of the DLG and RF3: spatial
accuracy and comprehensiveness from the DLG and network relationships, names,
stream level, and a unique identifier (reach code) for surface water features
from RF3. The NHD supersedes DLG and RF3 by incorporating them, not by
replacing them. Users of DLG and RF3 will find the National Hydrography Dataset
both familiar and greatly expanded and refined. The NHD provides a national
framework for assigning reach addresses to water-related entities, such as
industrial dischargers, drinking water supplies, fish habitat areas, wild and
scenic rivers. Reach addresses establish the locations of these entities
relative to one another within the NHD surface water drainage network in a
manner similar to street addresses. Once linked to the NHD by their reach
addresses, the upstream/downstream relationships of these water-related
entities and any associated information about them can be analyzed using
software tools ranging from spreadsheets to geographic information systems
(GIS). GIS can also be used to combine NHD-based network analysis with other
data layers, such as soils, land use and population, to help better understand
and display their respective effects upon one another. Furthermore, because the
NHD provides a nationally consistent framework for addressing and analysis,
water-related information linked to reach addresses by one organization
(national, state, local) can be shared with other organizations and easily
integrated into many different types of applications to the benefit of all. The
National Hydrography Dataset is designed to provide comprehensive coverage of
hydrologic data for the U.S. While initially based on 1:100,000-scale data, the
NHD is designed to incorporate - and encourage the development of -
higher-resolution data required by many users. It will facilitate the improved
integration of water-related data in support of the application requirements of
a growing national user community and will enable shared maintenance and
enhancement."
