Quantitative indicators are important to assess current watershed conditions, track future conditions and assess the vulnerability of these watersheds to future degradation. Building upon the U.S. Environmental Protection Agency (EPA) Preliminary Healthy Watershed Assessment (PHWA) framework, project analysts assembled and evaluated a set of candidate metrics characterizing multiple aspects of landscape condition, hydrology, geomorphology, habitat, biological condition and water quality for integration into an overall watershed health index. Geospatial analyses were structured, where possible, to leverage data from EPA StreamCat, the National Fish Habitat Partnership, the Chesapeake Bay model for nutrient loads and other regional data sources. A set of vulnerability metrics were derived representing aspects of land use change, water use, wildfire risk and climate change. Metric values were compiled for NHDPlus catchments in Maryland and the adjacent drainage area, and were used to assess conditions and vulnerability within the catchments associated with the current set of Tier II, state-identified healthy watersheds. The Maryland Healthy Watersheds Assessment (MDHWA) is a state-specific adaptation of the previously developed healthy watersheds assessment for the entire Chesapeake Bay watershed. Development of the MDHWA establishes a framework of watershed health and vulnerability metrics for assessing Maryland waters and watersheds, making use of more recent and refined regional data, and integrating state-specific data where possible. The assessment is intended to inform watershed management decision-making to sustain the health of state-identified healthy watersheds, which have been defined in Maryland as the watersheds associated with its designated high-quality, Tier II waters. The MDHWA will increase state capacity to better understand the broad spectrum of health and vulnerability issues affecting Maryland’s streams and healthy watersheds. This zipped file includes both the File Geodatabase data and ArcGIS Pro map package.

Digital Elevation Models (DEM) are widely used to derive information for the modeling of hydrologic processes. The basic model for hydrologic terrain analysis involving hydrologic conditioning, determination of flow field (flow directions) and derivation of hydrologic derivatives is available in multiple software packages and GIS systems. However as areas of interest for terrain analysis have increased and DEM resolutions become finer there remain challenges related to data size, software and a platform to run it on, as well as opportunities to derive new kinds of information useful for hydrologic modeling. This presentation will illustrate new functionality associated with the TauDEM software (http://hydrology.usu.edu/taudem) and new web based deployments of TauDEM to make this capability more accessible and easier to use. Height Above Nearest Drainage (HAND) is a special case of distance down the flow field to an arbitrary target, with the target being a stream and distance measured vertically. HAND is one example of a general class of hydrologic proximity measures available in TauDEM. As we have implemented it, HAND uses multi-directional flow directions derived from a digital elevation model (DEM) using the Dinifinity method in TauDEM to determine the height of each grid cell above the nearest stream along the flow path from that cell to the stream. With this information, and the depth of flow in the stream, the potential for, and depth of flood inundation can be determined. Furthermore, by dividing streams into reaches or segments, the area draining to each reach can be isolated and a series of threshold depths applied to the grid of HAND values in that isolated reach catchment, to determine inundation volume, surface area and wetted bed area. Dividing these by length yields reach average cross section area, width, and wetted perimeter, information that is useful for hydraulic routing and stage-discharge rating calculations in hydrologic modeling. This presentation will describe the calculation of HAND and its use to determine hydraulic properties across the US for prediction of stage and flood inundation in each NHDPlus reach modeled by the US NOAA’s National Water Model. This presentation will also describe two web based deployments of TauDEM functionality. The first is within a Jupyter Notebook web application attached to HydroShare that provides users the ability to execute TauDEM on this cloud infrastructure without the limitations associated with desktop software installation and data/computational capacity. The second is a web based rapid watershed delineation function deployed as part of Model My Watershed (https://app.wikiwatershed.org/) that enables delineation of watersheds, based on NHDPlus gridded data anywhere in the continental US for watershed based hydrologic modeling and analysis.

TwitterEach 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.

TwitterArc Hydro (AH) is a geospatial and temporal data model for water resources, which operates within ArcGIS and was developed by the GIS in Water Resources (GISWR) Consortium in the United States. The Consortium is comprised of several members including:
AH consists of a set of tools used to create and support a comprehensive water resources framework for hydrologic and related geospatial data analysis. The original focus of Arc Hydro was to support surface water modeling, but work has progressed into the groundwater realm. ESRI plans to link the two systems into one complete data modeling framework in the near future.
The Ministry of Natural Resources - Water Resources Information Program (WRIP) was involved in a multi-year project to develop standardized Arc Hydro surface water data sessions based on the Quaternary Watershed fabric for the Province of Ontario. Each session contains foundation layers required for fundamental hydrologic watershed analysis.
To meet the requirements of Arc Hydro, the project team followed rigorous quality checking and assurance procedures which resulted in extensive and significant base data improvements across the Province. These enhancements are regarded collectively as a 'snapshot' version of our hydrology base and derivative products. Base data updates are happening on a continual basis, which will have implications on any derivative or related product that has been produced to date by the Province. Any further work in Arc Hydro will depend on available resources and support from the various business areas interested in utilizing these data and tools.
Some key elements of the project include:

TwitterAs established by WAC 222-22-020, the state is divided into areas known as watershed administrative units (WAUs). WAU boundaries are defined by the Department of Natural Resources (DNR) in cooperation with the departments of Ecology, Fish and Wildlife, affected Indian tribes, local governments, forest land owners, and the public. This dataset is intended for use at 1:24,000 scale. WAU's are used by the Timber/Fish/Wildlife cooperators as the boundaries for watershed analysis studies and other natural resources management purposes on state and privately owned lands. WAU represents the administrative boundaries of 846 units. The boundaries are mainly along drainage divides (ridges), with some along rivers and other Washington State Department of Natural Resources (DNR) management boundaries. In the forested areas of the state WAUs range in size from 3,822 to 297,614 acres with a mean of 40,187 acres and a standard deviation of 26,697 acres. On the Columbia Plateau WAU areas range in size from 35,098 to 1,765,555 acres. This version of the WAU boundaries is current as of April 2006. Administrative boundaries based on hydrology form a general hierarchy. Water Resource Inventory Areas (WRIAs) are the largest unit, BASINs are subunits of WRIAs, and WAUs are subunits of BASINs. However, boundaries in this hierarchy do not necessarliy match in all areas. Where watershed analysis was been conducted, WAU boundaries may cross WRIA lines. Do not use WAU to derive WRIA boundaries. WRIA is managed and maintained by the Washington Department of Ecology.

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.

TwitterThis 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.

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.

TwitterNarragansett 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 watershed boundaries for the three estuaries, i.e., the areal extent of surface water drainage to the three estuaries, based on topographic, hydrologic, and other relevant landscape characteristics. The boundaries of the Narragansett Bay and the Southwest Coastal Ponds watersheds are sourced from the U.S. Geological Survey Watershed Boundary Dataset (WBD) which contains a nested, hierarchical system of hydrologic units. The boundaries of the Little Narragansett Bay watershed were constructed by combining WBD hydrologic unit boundaries for the Wood-Pawcatuck with an NBEP-delineated watershed area for the western portion of Little Narragansett Bay (which comprised a smaller outlet than any hydrologic unit available in the WBD). 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).
