The NHDPlus includes a stream network (based on the 1:100,00-scale NHD), improved networking, naming, and value-added attributes (VAAs). NHDPlus also includes elevation-derived catchments (drainage areas) produced using a drainage enforcement technique first widely used in New England, and thus referred to as \"the New England Method.\" This technique involves \"burning in\" the 1:100,000-scale NHD and when available building \"walls\" using the National Watershed Boundary Dataset (WBD). The resulting modified digital elevation model (HydroDEM) is used to produce hydrologic derivatives that agree with the NHD and WBD. Over the past two years, an interdisciplinary team from the U.S. Geological Survey (USGS), and the U.S. Environmental Protection Agency (USEPA), and contractors, found that this method produces the best quality NHD catchments using an automated process (USEPA, 2007).

The source data set represents land use and land cover for the conterminous United States for 2001. The National Land Cover Data Set for 2001 was produced through a cooperative project conducted by the Multi-Resolution Land Characteristics (MRLC) Consortium. The MRLC Consortium is a partnership of Federal agencies (http://www.mrlc.gov), consisting of the U.S. Geological Survey (USGS), the National Oceanic and Atmospheric Administration (NOAA), the U.S. Environmental Protection Agency (USEPA), the U.S. Department of Agriculture (USDA), the U.S. Forest Service (USFS), the National Park Service (NPS), the U.S. Fish and Wildlife Service (USFWS), the Bureau of Land Management (BLM), and the USDA Natural Resources Conservation Service (NRCS).\n\t\t\nThe NHDPlus Version 1.1 is an integrated suite of application-ready geospatial datasets that incorporates many of the best features of the National Hydrography Dataset (NHD) and the National Elevation Dataset (NED). The NHDPlus includes a stream network (based on the 1:100,00-scale NHD), improved networking, naming, and value-added attributes (VAAs). NHDPlus also includes elevation-derived catchments (drainage areas) produced using a drainage enforcement technique first widely used in New England, and thus referred to as \"the New England Method.\" This technique involves \"burning in\" the 1:100,000-scale NHD and when available building \"walls\" using the National Watershed Boundary Dataset (WBD). The resulting modified digital elevation model (HydroDEM) is used to produce hydrologic derivatives that agree with the NHD and WBD. Over the past two years, an interdisciplinary team from the U.S. Geological Survey (USGS), and the U.S. Environmental Protection Agency (USEPA), and contractors, found that this method produces the best quality NHD catchments using an automated process (USEPA, 2007). The NHDPlus dataset is organized by 18 Production Units that cover the conterminous United States.\n\t\t\nThe NHDPlus version 1.1 data are grouped by the U.S. Geologic Survey's Major River Basins (MRBs, Crawford and others, 2006). MRB1, covering the New England and Mid-Atlantic River basins, contains NHDPlus Production Units 1 and 2. MRB2, covering the South Atlantic-Gulf and Tennessee River basins, contains NHDPlus Production Units 3 and 6. MRB3, covering the Great Lakes, Ohio, Upper Mississippi, and Souris-Red-Rainy River basins, contains NHDPlus Production Units 4, 5, 7 and 9. MRB4, covering the Missouri River basins, contains NHDPlus Production Units 10-lower and 10-upper. MRB5, covering the Lower Mississippi, Arkansas-White-Red, and Texas-Gulf River basins, contains NHDPlus Production Units 8, 11 and 12. MRB6, covering the Rio Grande, Colorado and Great Basin River basins, contains NHDPlus Production Units 13, 14, 15 and 16. MRB7, covering the Pacific Northwest River basins, contains NHDPlus Production Unit 17. MRB8, covering California River basins, contains NHDPlus Production Unit 18.", - "distribution_titles": [ - "Digital Data", - "Original Metadata" - ], - "harvest_record": "https://catalog.data.gov/harvest_record/b03b41f9-784a-4cf2-b2c6-67aefcb8ba4d", - "harvest_record_raw": "https://catalog.data.gov/harvest_record/b03b41f9-784a-4cf2-b2c6-67aefcb8ba4d/raw", - "has_download": true, - "has_spatial": true, - "identifier": "http://datainventory.doi.gov/id/dataset/USGS_8524151b-ddd6-4d6c-a1d4-4240f0a3590b", - "keyword": [ - "CALI", - "COGB", - "California", - "Catchment", - "Conterminous United States", - "GLMR", - "Great Lakes, Ohio, Upper Mississippi, and Souris-Red-Rainy", - "Inlandwaters", - "LMTG", - "Lower Mississippi, Arkansas-White-Red, and Texas-Gulf", - "MORI", - "MRB", - "MRB1", - "MRB2", - "MRB3", - "MRB4", - "MRB5", - "MRB6", - "MRB7", - "MRB8", - "Major River Basin", - "Missouri", - "NAWQA", - "NEMA", - "NHDPlus", - "NLCD 2001 Land use and land cover", - "New England and Mid-Atlantic", - "PANW", - "Pacific Northwest", - "Rio Grande, Colorado, and Great Basin", - "SAGT", - "SPARROW", - "South Atlantic-Gulf and Tennessee", - "USGS:8524151b-ddd6-4d6c-a1d4-4240f0a3590b", - "environment", - "geoscientificInformation", - "inlandWaters" - ], - "last_harvested_date": "2026-09-17T00:49:08.390560", - "organization": { - "aliases": [ - "dept" - ], - "code_repo_exempt": false, - "code_repo_url": null, - "description": null, - "id": "143529f7-2eef-4a07-b227-93ac9e84fad8", - "logo": "https://raw.githubusercontent.com/GSA/logo/master/doi.png", - "name": "Department of the Interior", - "organization_type": "Federal Government", - "slug": "doi" - }, - "parent_identifier": null, - "popularity": 2, - "publisher": "U.S. Geological Survey", - "slug": "attributes-for-nhdplus-catchments-version-1-1-for-the-conterminous-united-states-nlcd-2001-8facd", - "spatial_centroid": { - "lat": 34.6090464, - "lon": -102.8775756 - }, - "spatial_shape": { - "coordinates": [ - [ - [ - -127.910792, - 23.243486 - ], - [ - -127.910792, - 51.657387 - ], - [ - -65.327751, - 51.657387 - ], - [ - -65.327751, - 23.243486 - ], - [ - -127.910792, - 23.243486 - ] - ] - ], - "type": "Polygon" - }, - "theme": [ - "geospatial" - ], - "title": "Attributes for NHDPlus Catchments (Version 1.1) for the Conterminous United States: NLCD 2001 Land Use and Land Cover", - "type": "dataset" - }, - { - "_score": 8.130148, - "_sort": [ - 1789606137958, - 8.130148, - 2, - "f2faa4de-e951-4ced-9980-5b7c97cc87ed" - ], - "dcat": { - "accessLevel": "public", - "bureauCode": [ - "010:12" - ], - "contactPoint": { - "@type": "vcard:Contact", - "fn": "Oklahoma-Texas Water Science Center", - "hasEmail": "mailto:gs-w-txpublic-info@usgs.gov" - }, - "description": "A previously developed groundwater flow model (https://doi.org/10.5066/P9051RUT) \nwas slightly modified to estimate the risk-based discrete relation between groundwater \nextraction and surface-water/groundwater exchange.

Ice-marginal positions, which represent pauses in the \nretreat of glacial ice from the region, favored the accumulation of coarse-grained deposits whereas \nmore steady or rapid ice retreat between these positions favored deposition of fine-grained lacustrine \ndeposits with limited coarse-grained deposits at depth. Unconfined aquifers with thick saturated \ncoarse-grained deposits are the most favorable settings for water-resource development, and three \nseveral-mile-long sections of valley were identified (mostly in Broome County) as potentially favorable: \n(1) the southernmost valley section, which extends from the New YorkPennsylvania border to about \n1 mile north of South Windsor, (2) the valley section that rounds the west side of the umlaufberg \n(an isolated bedrock hill within a valley) north of Windsor, and (3) the eastwest valley section at the \nBroome County Chenango County border from Nineveh to East of Bettsburg (including the
