StreamStats provides access to spatial analytical tools that are useful for water-resources planning and management, and for engineering and design purposes. The map-based user interface can be used to delineate drainage areas, get basin characteristics and estimates of flow statistics, and more. Available information varies from state to state.

StreamStats is a Web application that provides access to an assortment of Geographic Information Systems (GIS) analytical tools that are useful for water-resources planning and management, and for engineering and design purposes. The map-based user interface can be used to delineate drainage areas for user-selected sites on streams, and then get basin characteristics and estimates of flow statistics for the selected sites anywhere this functionality is available. StreamStats users also can select the locations of U.S. Geological Survey data-collection stations, shown as triangles on the StreamStats map, and get flow statistics and other information for the stations. The types of flow statistics that are available vary from state to state. A variety of additional tools are available for discovering information about streams and the activities along them.

StreamStats works within Web browser software on personal computers and mobile devices, and is best viewed using the latest versions of Internet Explorer, Microsoft Edge, Chrome, or Firefox. The browser must allow HTML5 asynchronous script execution. The application is being continually improved and expanded. The News link in our left-hand menu will provide notices of any new enhancements.

This dataset was produced by the U.S. Geological Survey (USGS) in cooperation with the Wyoming Water Development Office for the purpose of delineating drainage basins and performing hydrologic analysis in the Wyoming StreamStats application. The data are raster representations of the fundamental dataset layers necessary for the functionality of StreamStats application within the Wyoming StreamStats study area. The StreamStats application provides access to spatial analytical tools that are useful for water-resources planning and management, and for engineering and design purposes. The map-based user interface can be used to delineate drainage areas, calculate basin characteristics, and estimates of flow statistics, and more. The study boundary for data in this data release is defined by the extent of all HUC08 watersheds flowing in or out of the state of Wyoming.

The U.S. Geological Survey’s StreamStats program is a publicly-accessible web application (https://streamstats.usgs.gov) that can be used to delineate drainage areas, compute basin characteristics, and estimate flow statistics for user-selected locations on streams. StreamStats services are typically implemented at the statewide or watershed scale (referred to as state or basin applications), and although the three core functionalities remain consistent, many states have implemented custom tools to address specific water-resources planning and management needs. In Massachusetts, a watershed-scale application for the Mystic River Basin was developed to support stakeholder efforts to address stormwater challenges in this highly urbanized basin. The Mystic River Basin stormwater functionality was developed by incorporating 1-meter resolution lidar-derived elevation data and municipal storm drain data to accurately represent urban topography and stormwater flow (that is, subsurface piped flow). In the Mystic River Basin application, users can view the network of stormwater pipes and inlets, delineate drainage areas derived from lidar topography and stormwater infrastructure, and compute land-use/land-cover (LULC) basin characteristics. This data release contains the LULC data available in the Mystic River Basin StreamStats application as a Georeferenced Tagged Image File Format (GeoTIFF) raster dataset. This dataset was developed by processing Massachusetts 2016 LULC data (MassGIS, 2019) and Soil Survey Geographic data (SSURGO; NRCS, 2020) according to Massachusetts Department of Environmental Protection guidelines to produce categories consistent with the 2016 Massachusetts Small Municipal Separate Storm Sewer System (MS4) General Permit Pollutant Loading Export Rates for aggregated land uses (Schifman, 2022).

The U.S. Geological Survey, in cooperation with Maine Department of Transportation, has compiled a series of GIS datasets to be implemented into the USGS StreamStats application for the State of Maine.These data were compiled from the high-resolution National Hydrography Dataset (NHD) and the Maine Lidar-Derived Watersheds (Sturtevant and Schoen, 2022). By using these datasets users will be able to delineate watersheds with the StreamStats application more accurately than previously possible. The datasets are provided in five separate child items.

These datasets consist of a workspace (folder) containing a collection of gridded datasets plus a personal geodatabase containing several vector datasets. These datasets are designed to be used with the ArcHydro Tools, developed by ESRI in partnership with the U.S. Geological Survey, StreamStats Development Team. The datasets, together with the ArcHydro Tools, allow users to delineate watersheds and compute several watershed characteristics. The datasets are distributed in folders named for the 8-digit Hydrologic Unit Code (HUC) each covers. The data structure is the same for each HUC.

This dataset consists of a workspace (folder) containing four gridded datasets and a personal geodatabase. The gridded datasets are a grid of mean annual precipitation, a grid of forest land cover, and region grids used in the Idaho StreamStats application. One region grid is for peak flow estimates, the other is for low flows, mean annual flows, and monthly flow statistics. The personal geodatabase contains a polygon feature class of exclusion polygons, which identify areas in which use the StreamStats application is restricted.

The U.S. Geological Survey (USGS), in cooperation with the Puerto Rico Environmental Quality Board, has compiled a series of geospatial datasets for Puerto Rico to be implemented into the USGS StreamStats application (https://streamstats.usgs.gov/ss/). These geospatial datasets, along with basin characteristics datasets for Puerto Rico published as a separate USGS data release (https://doi.org/10.5066/P9HK9SSQ), were used to delineate watersheds and develop the peak-flow and low-flow regression equations used by StreamStats. The geospatial dataset described herein are the stream link rasters at a 10-m resolution. A number is assigned to a reach of stream located between junctions (such as tributary junctions). Stream link raster contains unique values for each stream segment defined by str. Data are partitioned into four TIFF files, one for each of the four 8-digit Hydrologic Unit Code (HUC) areas for Puerto Rico: 21010002, 21010003, 21010004, and 21010005.

The U.S. Geological Survey (USGS), in cooperation with the New Jersey Department of Environmental Protection (NJDEP), calculated several basin characteristics as part of the updated New Jersey StreamStats 2022 application (U.S. Geological Survey, 2022). These datasets are raster representations of various environmental, geological, and land use attributes within the New Jersey StreamStats 2022 study area; they are applied in the New Jersey 2022 application to describe delineated watersheds. This update features improvements in base elevation resolution from 10 meters to 10 feet and stream centerline hydrography from 1:24,000 to 1:2,400, as well as resampling of previously existing datasets to match the 10-foot resolution. The sixteen 8-digit Watershed Boundary Dataset Hydrologic Unit Codes (HUCs) represented by these datasets are 02020007, 02030103, 02030104, 02030105, 02040101, 02040102, 02040103, 02040104, 02040105, 02040106, 02040201, 02040202, 02040203, 02040206, 02040301, and 02040302 (U.S. Geological Survey, 2016). The StreamStats application provides access to spatial analytical tools that are useful for water-resources planning and management, as well as engineering and design purposes. The map-based user interface can be used to delineate drainage areas, determine basin characteristics and estimate flow statistics, including instantaneous flood discharge, monthly flow-duration, and monthly low-flow frequency statistics for ungaged streams.
