| Michigan Water Withdrawal Assessment Tool | Michigan’s Water Withdrawal Assessment Process is used to regulate new or increased large quantity withdrawals (more than 100,000 gallons of water per day) from any source for the purpose of preventing adverse resource impacts on streams. The Water Withdrawal Assessment Process is ecologically based, built around a stream classification system, expected fish communities for those classifications and modeled fish community responses to streamflow changes resulting from withdrawals of varied magnitude. Through the legislative process, maximum withdrawals allowed were determined and defined in statute. To facilitate decision making, an online screening tool was developed to estimate the impact of withdrawing water on the nearby stream ecosystems. Proposed withdrawals with a high likelihood for adverse resource impacts require further site-specific investigation for permitting decisions. | Watershed Assessment; Watershed Protection | Data and Tools; Technical Report | Hydrology | State | Michigan | Region 5 | Michigan Department of Environment, Great Lakes and Energy |
| Regional-scale Habitat Suitability Model to Assess the Effects of Flow Reduction on Fish Assemblages in Michigan Streams | This model was developed as part of Michigan’s Water Withdrawal Assessment Process to predict changes in characteristic fish assemblages in 11 stream types throughout Michigan due to base flow changes resulting from water withdrawals.

| Tool for Estimating Streamflow for Pennsylvania Waterways | Water-resource managers use daily mean streamflows to generate streamflow statistics and analyze streamflow conditions. An in-depth evaluation of flow regimes to promote instream ecological health often requires streamflow information obtainable only from a time series hydrograph. Historically, it has been difficult to estimate daily mean streamflow for an ungaged location. The U.S. Geological Survey, in cooperation with the Pennsylvania Department of Environmental Protection, Susquehanna River Basin Commission and The Nature Conservancy, has developed the Baseline Streamflow Estimator (BaSE) to estimate baseline streamflow at a daily time scale for ungaged streams in Pennsylvania using data collected during water years 1960–2008. | Watershed Assessment | Data and Tools; Technical Report | Hydrology | State | Pennsylvania | Region 3 | U.S. Geological Survey; Pennsylvania Department of Environmental Protection; Susquehanna River Basin Commission; The Nature Conservancy |
| Application of the Richards-Baker Flashiness Index to Gaged Michigan Rivers and Streams | Stream flashiness is a stream flow response to storms. Streams that rise and fall quickly are considered flashier than those that maintain a steadier flow. This report describes an analysis of trends in stream flashiness for streams throughout Michigan. The information can be incorporated into stream stability assessments and watershed management plans. Watershed stakeholders should also find it useful as an aid to Best Management Practices (BMPs) selection and design. | Watershed Assessment | Technical Report | Hydrology; Geomorphology | State | Michigan | Region 5 | Michigan Department of Environment, Great Lakes and Energy |
| National Ecological Framework | The National Ecological Framework is a geospatial model of the connectivity of natural landscapes in the lower 48 United States. It was developed to guide the protection of the natural ecosystem processes that give us clean air, pure water and protected lands that are part of the EPA’s mission to protect. The National Ecological Framework follows a hub/corridor approach: large patches of ecologically significant areas are delineated as ecological hubs and corridors are delineated as the least-disturbed pathways between hubs. Potential uses of the National Ecological Framework include highway and residential development planning to minimize disturbance, wetland mitigation to maximize landscape connectivity and designation of greenways to maintain existing connections. | Watershed Assessment | Data and Tools | Landscape Condition | National | National | National | U.S. Environmental Protection Agency |
| A National Streamflow Network Gap Analysis | USGS conducted an assessment of the ability of its stream gage network to produce various streamflow statistics at locations that have stream gages in place (gaged) and that do not have stream gages (ungaged). The assessment identifies where gaps exist in the network of gaged locations, explains how accurately useful statistics can be calculated with a given length of record and notes whether the current network allows for estimation of these statistics at ungaged locations. The results of the assessment indicate that coverage provided by the streamflow data-collection network varies both spatially and temporally. The goal of this study was to help USGS identify and strategically address the existing gaps in the stream flow network. | Watershed Assessment | Technical Report | Hydrology | National | National | National | U.S. Geological Survey |

Indicators of watershed health were quantified using a combination of existing GIS layers and statistical models that estimated values of stream condition metrics (for example, chemical constituent concentrations and biological condition scores). The assessment also incorporated available field sampling data on mussel conditions. The results of the assessment can be applied identify healthy areas which could be prioritized for watershed protection efforts. | Watershed Assessment | Technical Report | Integrated Assessment | Local | Tennessee | Region 4 | U.S. Environmental Protection Agency |
| Montana Prairie Wetlands and Intermittent/Ephemeral Streams: Hydrologic Needs Assessment for Healthy Watersheds | This project was conducted to address the hydrologic needs for healthy watersheds in Montana. Through a two-step process involving the development of hydrology–ecology hypotheses and a case study analysis of one of these hypotheses, it was demonstrated that precautionary limits of hydrologic alteration can be determined for the prairie wetlands of Montana. Twenty hydrology–ecology hypotheses addressing macroinvertebrates, fish, amphibians and birds were identified for individual- and landscape-level wetlands and intermittent/ephemeral steams. One of the hypotheses was then selected for a case study analysis to develop a proof-of-concept model relationship that describes hydrological alteration and ecological condition and supports the development of precautionary limits of hydrologic alteration. | Watershed Assessment; Watershed Protection | Technical Report | Hydrology | State | Montana | Region 8 | U.S. Environmental Protection Agency |
| Overview of the Preliminary Healthy Watersheds Assessments Project | This preliminary assessment provides a “first cut” product nationwide at a small watershed scale, with individual statewide summaries intended to help states and others without Healthy Watersheds Assessments engage in watershed protection planning and prioritizing. The integrated assessment approach involves scoring watersheds with indices of Watershed Health (landscape condition, habitat condition, hydrologic condition, geomorphic condition, biological condition and water quality) and Watershed Vulnerability (risks from land use change, water use and wildfire). In addition to statewide assessment, the preliminary assessment scores and compares each ecoregion’s watersheds. This enables state-level users to be aware of any watershed's condition and vulnerability relative to its ecoregion as well as relative to watersheds across the state. | Watershed Assessment | Data and Tools; Technical Report | Integrated Assessment | National | National | National | U.S. Environmental Protection Agency |
