The Lakes Ecosystem Services Online GIS provides geospatial visualization, query, and analysis tool on the types of benefits provided by lakes, ponds, and reservoirs. The data in this dataset is used by the website to provide access to lakes monitoring data, modeled nutrient fluxes, state specific data sets analytical tools and scripts for exploring associations between nutrients and lake ecosystem services, tools for mapping lake ecosystem services. https://archive.epa.gov/aed/lakesecoservices/web/html/ Internet Archive URL: https://web.archive.org/web/*/http://gispub4.epa.gov/LES

National Hydrography Dataset

The data shows Ordnance Survey pond locations, where they match with the surveyed location of a priority habitat pond. The location and attributes of these priority habitat ponds does not currently exists for end users, ecologists, community groups and other stakeholders. The layer will be used to identify, conserve and enhance these features.OS Ponds (taken from the MasterMap Topography layer hydrology>static water) that have a matching pond survey (Clean Water for Wildlife of Priority Ponds) (see data within this folder for these layers) within their geometry, or within 30m of their edge. proximity was created (using NEAR tool) for points and then simplified (to remove 1 to many relationship) and joined to OS polygons using FID unique value. Unnecessary OS fields have been deleted.Full metadata can be viewed on data.gov.uk.

(Link to Metadata) VHDCARTO is a simplified version of the local resolution Vermont Hydrography Dataset (VHD) that has been enriched with stream perenniality, e.g., "intermittent" vs. "perennial", as well as, Strahler stream order attribution for the single linear feature class only. The primary means of accessing this information cartographically is via the FCODE and STREAM_ORDER fields, respectively. See the Entity and Attribution Information section for details. NOTE! Perenniality data does not exist for stream reaches contained within, or intersected by, Essex or Caledonia counties, thus the FCODE "46000" in these areas. The absence of Soil SUrvey GeOgraphic (SSURGO) database information in these areas precluded the computation of perenniality. These areas will be processed at some future date. For information on the FCODE symbol for attribution or analysis see the following document https://www.usgs.gov/national-hydrography/national-hydrography-dataset (NHDFlowline). A two dimensional feature class for lakes, ponds and larger streams is also included in VHDCARTO. Both layers are derived from the latest National Hydrography Dataset (NHD) data. The NHD is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. For information on the science behind computing perenniality attribution please refer to the following U.S. Geological Survey Scientific Investigative Report (SIR) # 2006-5217 - https://pubs.usgs.gov/sir/2006/5217/pdf/SIR2006-5217_report.pdf

(Link to Metadata) The Vermont Hydrography Dataset (VHD) is compliant with the local resolution (also known as High Resolution) National Hydrography Dataset (NHD) and is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. Data users are highly encouraged to read this metadata thoroughly in order to avoid using the data beyond its limitations. This dataset is ONLY available for download from USGS's FTP site as a pre-staged ESRI File Geodatabase only (shapefile not available). Refer to VHDCARTO if you're looking for a layer of surface water data for cartographic purposes only. The VHD is based primarily on the Vermont Mapping Program (VMP) digital orthophotos, vmp "break line" features, and to a lesser degree on historical surface water data, NAPP cir multi-spectral aerial photography and CIR satellite imagery (lamoille and white subbasins only). The original VMP orthos had source dates ranging from 1994-2000 and these are being updated yearly. The VHD is organized at the subbasin level, a.k.a., the eight digit cataloging unit (HUC 8). The 17 Subbasins within or intersecting Vermont include: Black-Ottauquechee Rivers (1080106), Connecticut-Bellows Falls to Vernon Dam (1080107), Connecticut-Johns River to Waits River (1080103), Connecticut-Waits River to White River (1080104), Deerfield River (1080203), Hudson-Hoosic Rivers (2020003), Lake Champlain (2010008), Lake George (2010001), Lamoille River (2010005), Middle Connecticut River (1080201), Mississquoi River (2010007), Otter Creek (2010002), Passumpsic River (1080102), St. Francois River (1110000), Upper Connecticut River (1080101), White River (1080105) and Winooski River (2010003).

A Lake Champlain subset of the VHDCARTO dataset--which is a simplified cartographic-purpose version of the local resolution Vermont Hydrography Dataset (VHD).The full VHDCARTO dataset is composed of two layers--a line layer and a polygon layer.

This web map contains datasets representing the National Hydrography Dataset (NHD) of Washington State, labels for NHD features, and the Watershed Boundary Dataset (WBD) basins for Hydrologic Unit Code (HUC) levels 4, 8, and 12. The NHD dataset has been adopted as the Washington State hydrography standard. The NHD is a national framework for assigning reach addresses to water-related entities, such as industrial discharges, 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, much like addresses on streets. 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 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.This high-resolution NHD, generally developed at 1:24,000/1:4,800 scale. Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water bodies. The NHD also incorporates the National Spatial Data Infrastructure framework criteria established by the Federal Geographic Data Committee.This map contains a BETA version of WaterType attached to the Skagit River Basin NHDflowlines. This Beta version of the Watertype is the result of a pilot project and will be refined over the next six months. The field is for users of NHD who want access to Water Type and who are not under Forest Practices rules. The WaterType uses Shorelines Master Program type S streams and Fish Presence Data from both WA Dept Natural Resources and WA Dept Fish and Wildlife.
