This data release includes GIS datasets supporting the Colorado Legacy Mine Lands Watershed Delineation and Scoring tool (WaDeS), a web mapping application available at https://geonarrative.usgs.gov/colmlwades/. Water chemistry data were compiled from the U.S. Geological Survey (USGS) National Water Information System (NWIS), U.S. Environmental Protection Agency (EPA) STORET database, and the USGS Central Colorado Assessment Project (CCAP) (Church and others, 2009). The CCAP study area was used for this application. Samples were summarized at each monitoring station and hardness-dependent chronic and acute toxicity thresholds for aquatic life protections under Colorado Regulation No. 31 (CDPHE, 5 CCR 1002-31) for cadmium, copper, lead, and/or zinc were calculated. Samples were scored according to how metal concentrations compared with acute and chronic toxicity thresholds. The results were used in combination with remote sensing derived hydrothermal alteration (Rockwell and Bonham, 2017) and mine-related features (Horton and San Juan, 2016) to identify potential mine remediation sites within the headwaters of the central Colorado mineral belt. Headwaters were defined by watersheds delineated from a 10-meter digital elevation dataset (DEM), ranging in 5-35 square kilometers in size. Python and R scripts used to derive these products are included with this data release as documentation of the processing steps and to enable users to adapt the methods for their own applications.

This layer shows a multi-component analysis for California stream gage priorities at the Hydrologic Unit Code 12 (HUC12) watershed resolution. The Stream Gage Prioritization Analysis is part of the Senate Bill 19 Stream Gaging Plan, which seeks to prioritize areas for additional stream gaging efforts. The dataset includes the gaged proportion of each HUC12 based on a Gage Gap Analysis and information on prioritization results based on five management criteria. The management criteria include scores for ecosystem, water quality, water supply, flood, and reference gages. The priorities are the top scoring 200 watersheds for each management criteria area, for a total of 921 watersheds with overlap between the priorities. The 921 priorities are assigned a primary (highest scoring) benefit. Included is the presence of gages that could be reactivated or upgraded in the watershed. The presence of underrepresented communities, as defined in the Department of Water Resources DAC Mapping Tool, is also noted for each watershed.parameterRangeDescriptionhuc124469California huc12 watershed, of which there are 4469 totalhuc12_name Name of the huc12 watershedhuc101039California huc10 watershed, of which there are 1039 totalhuc10_name Name of the huc10 watershedfirst_in_huc100 or 1first time this huc10 appears in a ranked list; for hucXX_multibenefit, the master rank is hucXX_rank_combinedprimary benefit top scoring management criteria, if in top 100 or 200; if "multibenefit topranks", it scores in top 100 in multiple categories; if "combined above median", it scores in the top 200 in no categories but the sum of the scores is in the top 200prop_need_gage0 - 1Proportion of huc12 watershed that is ungaged, by stream segment lengthhuc12_gg_combined0 - 4Sum ecosystem_gg, watersupply_gg, waterquality_gg, and flood_gghuc12_gg_combined_ref0 - 5Same as huc12_gg_combined plus reference_priority_score_01ecosystem_gg0 – 1Final ecosystem score = ecosystem_raw x prop_need_gageecosystem_rank1-4096Final ecosystem ranking based on ecosystem_gg, with 1 the highest.

USGS24"SBAS" was orginally created by USGS as part of a cooperative effort between the USGS and DEP to create a statewide basin or watershed map. SRWMD has modified and added some watersheds because of local knowledge and needs of the District. A number of items have also been added to the coverage. Surfacewater watersheds are topographic land features which contain a unique hydrologic area of surface drainage. Suwannee River Water Management has choosen to call this a watershed map instead of a basin map as previously called. These spatial data sets provide SRWMD and other government agencies with a consolidated resource for watershed information at various levels of geographic extent. The data sets are intended to support watershed analysis, planning, permitting, regulatory, and other functions at SRWMD. They have been edited and modified by the District to reflect better information available at the regional level, and to better meet the specific needs of the GIS users at SRWMD. A guide to the Watershed coverage is available from SRWMD at md_lib/basins/items.doc. A spreadsheet that expains the attribution of both the polygon and arc attribute tables is also located at md_lib/basins/sbas_items.doc.

The Automated Geospatial Watershed Assessment (AGWA) tool is a GIS-based hydrologic modeling tool that uses commonly available GIS data layers to fully parameterize, execute, and spatially visualize results for the RHEM, KINEROS2, KINEROS-OPUS, SWAT2000, and SWAT2005 watershed runoff and erosion models. Accommodating novice to expert GIS users, it is designed to be used by watershed, water resource, land use, and resource managers and scientists investigating the hydrologic impacts of land-cover/land-use change in small watershed to basin-scale studies. AGWA is currently available as AGWA 1.5 for ArcView 3.x, AGWA 2.x for ArcGIS 9.x, and AGWA 3.X for ArcGIS 10.x. Planning and assessment in land and water resource management are evolving from simple, local-scale problems toward complex, spatially explicit regional ones. Such problems have to be addressed with distributed models that can compute runoff and erosion at different spatial and temporal scales. The extensive data requirements and the difficult task of building input parameter files, however, have long represented an obstacle to the timely and cost-effective use of such complex models by resource managers. The USDA- ARS Southwest Watershed Research Center, in cooperation with the U.S. EPA Office of Research and Development Landscape Ecology Branch, the University of Arizona, and the University of Wyoming, has developed a GIS tool to facilitate this process. A geographic information system (GIS) provides the framework within which spatially-distributed data are collected and used to prepare model input files and evaluate model results. AGWA uses widely available standardized spatial datasets that can be obtained via the internet. The data are used to develop input parameter files for two watershed runoff and erosion models: KINEROS2 and SWAT.

This dataset refers to topographic constraints and land use feedbacks affecting surface water dynamics in the Tapajós River Basin, Brazilian Amazon.

Each drainage area is considered a Hydrologic Unit (HU) and is given a Hydrologic Unit Code (HUC) which serves as the unique identifier for the area. HUC 2s, 6s, 8s, 10s, & 12s, define the drainage Regions, Subregions, Basins, Subbasins, Watersheds and Subwatersheds, respectively, across the United States. Their boundaries are defined by hydrologic and topographic criteria that delineate an area of land upstream from a specific point on a river and are determined solely upon science based hydrologic principles, not favoring any administrative boundaries, special projects, or a particular program or agency. The Watershed Boundary Dataset is delineated and georeferenced to the USGS 1:24,000 scale topographic basemap.Hydrologic Units are delineated to nest in a multi-level, hierarchical drainage system with corresponding HUCs, so that as you move from small scale to large scale the HUC digits increase in increments of two. For example, the very largest HUCs have 2 digits, and thus are referred to as HUC 2s, and the very smallest HUCs have 12 digits, and thus are referred to as HUC 12s.Dataset SummaryPhenomenon Mapped: Watersheds in the United States, as delineated by the Watershed Boundary Dataset (WBD)Geographic Extent: Contiguous United States, Alaska, Hawaii, Puerto Rico, Guam, US Virgin Islands, Northern Marianas Islands and American SamoaProjection: Web MercatorUpdate Frequency: AnnualVisible Scale: Visible at all scales, however USGS recommends this dataset should not be used for scales of 1:24,000 or larger.Source: United States Geological Survey (WBD)Data Vintage: January 7, 2025What can you do with this layer?This layer is suitable for both visualization and analysis acrossthe ArcGIS system.

This resource contains data inputs and a Jupyter Notebook that is used to introduce Hydrologic Analysis using Terrain Analysis Using Digital Elevation Models (TauDEM) and Python. TauDEM is a free and open-source set of Digital Elevation Model (DEM) tools developed at Utah State University for the extraction and analysis of hydrologic information from topography. This resource is part of a HydroLearn Physical Hydrology learning module available at https://edx.hydrolearn.org/courses/course-v1:Utah_State_University+CEE6400+2019_Fall/about

In this activity, the student learns how to (1) derive hydrologically useful information from Digital Elevation Models (DEMs); (2) describe the sequence of steps involved in mapping stream networks, catchments, and watersheds; and (3) compute an approximate water balance for a watershed-based on publicly available data.

Please note that this exercise is designed for the Logan River watershed, which drains to USGS streamflow gauge 10109000 located just east of Logan, Utah. However, this Jupyter Notebook and the analysis can readily be applied to other locations of interest. If running the terrain analysis for other study sites, you need to prepare a DEM TIF file, an outlet shapefile for the area of interest, and the average annual streamflow and precipitation data. - There are several sources to obtain DEM data. In the U.S., the DEM data (with different spatial resolutions) can be obtained from the National Elevation Dataset available from the national map (http://viewer.nationalmap.gov/viewer/). Another DEM data source is the Shuttle Radar Topography Mission (https://www2.jpl.nasa.gov/srtm/), an international research effort that obtained digital elevation models on a near-global scale (search for Digital Elevation at https://www.usgs.gov/centers/eros/science/usgs-eros-archive-products-overview?qt-science_center_objects=0#qt-science_center_objects). - If not already available, you can generate the outlet shapefile by applying basic terrain analysis steps in geospatial information system models such as ArcGIS or QGIS. - You also need to obtain average annual streamflow and precipitation data for the watershed of interest to assess the annual water balance and calculate the runoff ratio in this exercise. In the U.S., the streamflow data can be obtained from the USGS NWIS website (https://waterdata.usgs.gov/nwis) and the precipitation from PRISM (https://prism.oregonstate.edu/normals/). Note that using other datasets may require preprocessing steps to make data ready to use for this exercise.

The United States is divided and sub-divided into successively smaller hydrologic units which are classified into four levels: regions, subregions, accounting units, and cataloging units. The hydrologic units are arranged or nested within each other, from the largest geographic area (regions) to the smallest geographic area (cataloging units). Each hydrologic unit is identified by a unique hydrologic unit code (HUC) consisting of two to eight digits based on the four levels of classification in the hydrologic unit system. The intent of defining Hydrologic Units (HU) within the Watershed Boundary Dataset is to establish a base-line drainage boundary framework, accounting for all land and surface areas. Hydrologic units are intended to be used as a tool for water-resource management and planning activities particularly for site-specific and localized studies requiring a level of detail provided by large-scale map information. The WBD complements the National Hydrography Dataset (NHD) and supports numerous programmatic missions and activities including: watershed management, rehabilitation and enhancement, aquatic species conservation strategies, flood plain management and flood prevention, water-quality initiatives and programs, dam safety programs, fire assessment and management, resource inventory and assessment, water data analysis and water census. The Watershed Boundary Dataset (WBD) is a comprehensive aggregated collection of hydrologic unit data consistent with the national criteria for delineation and resolution. It defines the areal extent of surface water drainage to a point except in coastal or lake front areas where there could be multiple outlets as stated by the "Federal Standards and Procedures for the National Watershed Boundary Dataset (WBD)" "Standard" (http://pubs.usgs.gov/tm/11/a3/). Watershed boundaries are determined solely upon science-based hydrologic principles, not favoring any administrative boundaries or special projects, nor particular program or agency. This dataset represents the hydrologic unit boundaries to the 12-digit (6th level) for the entire United States. Some areas may also include additional subdivisions representing the 14- and 16-digit hydrologic unit (HU). At a minimum, the HUs are delineated at 1:24,000-scale in the conterminous United States, 1:25,000-scale in Hawaii, Pacific basin and the Caribbean, and 1:63,360-scale in Alaska, meeting the National Map Accuracy Standards (NMAS). Higher resolution boundaries are being developed where partners and data exist and will be incorporated back into the WBD. WBD data are delivered as a dataset of polygons and corresponding lines that define the boundary of the polygon. WBD polygon attributes include hydrologic unit codes (HUC), size (in the form of acres and square kilometers), name, downstream hydrologic unit code, type of watershed, non-contributing areas, and flow modifications. The HUC describes where the unit is in the country and the level of the unit. WBD line attributes contain the highest level of hydrologic unit for each boundary, line source information and flow modifications.View Dataset on the Gateway

The Watershed Health Assessment Framework (WHAF) mapping application was developed to support natural resource management through an approach that emphasizes ecosystem health.

The WHAF application delivers a suite of watershed health index scores, each index represents a unique facet of the ecosystem. The index scores are organized within the five components of ecosystem Health: Hydrology, Geomorphology, Biology, Connectivity, and Water Quality. This 5-Component model provides a consistent structure for delivering a balanced and repeatable exploration of watershed conditions.

In addition to health scores, the application provides access to:
- Watershed boundaries with tools to visualize patterns of water movement.
- 100+ GIS data layers that provide insights to support natural resource management decisions and planning efforts.
- The ability to chart land cover at each watershed scale.
- The ability to save and share interactive map layouts through custom links and bookmarks.

The WHAF application is accessible from any modern web browser, although we recommend using a recent version of Google Chrome or Mozilla Firefox.

The WHAF health scores are also available for use in desktop GIS software, the data can be downloaded from Watershed Health Assessment Scores.

Data delivered through the application varies in origin and date of publication. Every effort is made to use the most current data available, and keep resources in sync with updates made to the source data. For detailed information regarding the data used to derive health scores, consult the health score analysis documentation. For detailed information regarding the source and publication data of additional GIS layers, consult the GIS Data Sources list.

The state recognizes the importance of stream gaging information. A robust and reliable stream gage network can help state, federal, and local agencies manage water resources and conserve freshwater species more effectively for multiple benefits and help to avoid conflicts.Senate Bill No. 19 (SB 19) (Statutes of 2019, Chapter 361, Dodd) enacts Water Code section 144, which directs the Department of Water Resources (DWR) and the State Water Resources Control Board (State Water Board) to develop a plan to address gaging information gaps through the deployment of a network of prioritized stream gages in consultation with the California Department of Fish and Wildlife (CDFW), Department of Conservation (DOC), the Central Valley Flood Protection Board (Flood Board), and interested stakeholders. The stream gaging plan will identify significant gaps in the stream gaging network to meet the wide variety of water management needs, which are increasingly important in the face of a changing climate. It is anticipated it will take two years to develop the plan.This web map displays some preliminary results from the Stream Gage Prioritization Analysis undertaken as part of the Senate Bill 19 Stream Gaging Plan.

Each drainage area is considered a Hydrologic Unit (HU) and is given a Hydrologic Unit Code (HUC) which serves as the unique identifier for the area. HUC 2s, 6s, 8s, 10s, & 12s, define the drainage Regions, Subregions, Basins, Subbasins, Watersheds and Subwatersheds, respectively, across the United States. Their boundaries are defined by hydrologic and topographic criteria that delineate an area of land upstream from a specific point on a river and are determined solely upon science based hydrologic principles, not favoring any administrative boundaries, special projects, or a particular program or agency. The Watershed Boundary Dataset is delineated and georeferenced to the USGS 1:24,000 scale topographic basemap.Hydrologic Units are delineated to nest in a multi-level, hierarchical drainage system with corresponding HUCs, so that as you move from small scale to large scale the HUC digits increase in increments of two. For example, the very largest HUCs have 2 digits, and thus are referred to as HUC 2s, and the very smallest HUCs have 12 digits, and thus are referred to as HUC 12s.Dataset SummaryPhenomenon Mapped: Watersheds in the United States, as delineated by the Watershed Boundary Dataset (WBD)Geographic Extent: Contiguous United States, Alaska, Hawaii, Puerto Rico, Guam, US Virgin Islands, Northern Marianas Islands and American SamoaProjection: Web MercatorUpdate Frequency: AnnualVisible Scale: Visible at all scales, however USGS recommends this dataset should not be used for scales of 1:24,000 or larger.Source: United States Geological Survey (WBD)Data Vintage: January 7, 2025What can you do with this layer?This layer is suitable for both visualization and analysis acrossthe ArcGIS system.

Narragansett Bay, Little Narragansett Bay, and the Southwest Coastal Ponds are the three estuarine study areas under the purview of the Narragansett Bay Estuary Program. This dataset represents the 10-digit hydrologic units (HUC10) that drain, directly and indirectly, to the three estuaries. HUC10 drainage areas were sourced from the U.S. Geological Survey (USGS) Watershed Boundary Dataset (WBD) which contains a nested, hierarchical system of hydrologic units. Hydrologic units define the boundaries of surface water drainage to a given set of outlet points or a dendritic stream network. The boundaries are determined by topographic, hydrologic, and other relevant landscape characteristics. Within the Little Narragansett Bay watershed, NBEP delineated the drainage area for the western portion of Little Narragansett Bay. This area, “Part of Southeast Coastal-Pawcatuck River to Eastern Point,” drains to a smaller outlet than any hydrologic unit available in the WBD. All coastal watershed boundaries were updated with NBEP’s estuarine coastline delineation (for details about NBEP’s coastline delineation, see metadata for BAYS_NBEP2019). This dataset is intended for use in general planning, GIS analysis, and mapping at watershed and subwatershed scales. For more information, please reference the 2017 State of Narragansett Bay & Its Watershed Technical Report (nbep.org).
