This dataset provides the results of an assessment of estuary habitat condition in the conterminous United States. To analyze estuary condition, a cumulative disturbance index was developed based on habitat stressor variable data available at a national scale for anthropogenic disturbances measured within estuaries and their associated watersheds. Twenty-eight variables were combined within stressor categories to develop four sub-indices of disturbance for land use, alterations of river flows, pollution sources, and estuary eutrophication. These four sub-indices of disturbance were then combined to develop cumulative disturbance index scores for each estuary. This index describes the estimated combined stress on...
We will develop a set of linked models to help predict the effects of climate change on rivers and endangered species. These will include watershed- and reach-scale models to predict streamflow, water temperatures, and other fish habitat metrics under various climatic scenarios for the reaches used by species listed under the Endangered Species Act (ESA), plus a combined bioenergetics and life-cycle model (to be done by the U.S. Geological Survey [USGS]) to assess the impact of these factors on fish growth, reproduction, and survival. We propose to test the model framework at a site on the Methow River, Washington, to explore additional opportunities for collaboration and model development.

Great Lakes fishery managers and stakeholders have little information regarding how climate change could affect the management of recreationally and commercially important fisheries, which have been valued at more than $7 billion annually. Our research has focused on how climate change could influence fish habitat (including water temperature, ice cover, and water levels), phytoplankton production, and ultimately fish production. Focusing on lakes Michigan and Huron, this webinar provids information about: whether we can detect climate signals in long-term data on fisheries and phytoplankton preliminary climate (e.g., water temperature, ice cover) forecasts for 2043-2065 how future climate could influence growth...
We evaluated the role of major tributary streams for endangered fish recovery using a matrix approach based on quantitative information. However, the need for ranking tributaries for direct and indirect contributions (i.e., assignment of high, medium or low importance) required a more subjective approach. Some streams differed in actual and potential importance because barriers deny fish access to suitable habitat. We have not assigned relative importance to the different types of contributions; to a large extent that may involve policy issues better addressed by the Recovery Program.

Landscape level stratification of ecoregions in the Blue Mountain study area. Study area was defined by watershed boundaries because the pathways and distribution of anadromous fish and determined by watershed linkages and landscape characteristics.
The Regional Estuary Assessment for the northern Gulf of Mexico represents an effort to develop, test, and implement a new assessment methodology for marine habitats that improves the analytical basis for identifying impacts to estuary fish habitats. Building from work completed for the National Estuary Assessment, this approach includes: 1) information on fish and shellfish presence/absence from over 70,000 sampling events collected over two decades, to better relate fish habitat condition to natural and anthropogenic variables; 2) data on natural factors, to better incorporate information on the natural susceptibility of individual estuaries; and 3) regional datasets not available on a nationally-consistent basis....

Great Lakes fishery managers and stakeholders have little information regarding how climate change could affect the management and conservation of fish populations, including those of high recreational and commercial value. USGS scientists worked closely with state management agencies and the National Wildlife Federation to complete several objectives that provide knowledge to aid their planning and management strategies in anticipation of coming changes. First, researchers updated a regional Great Lakes climate model to predict water level changes, water temperatures, and ice cover data for the entire Great Lakes basin 50-100 years into the future. Second, researchers used satellite data to determine whether the...
Many inland waters across the United States are experiencing warming water temperatures. The impacts of this warming on aquatic ecosystems are significant in many areas, causing problems for fisheries management, as many economically and ecologically important fish species are experiencing range shifts and population declines. Fisheries and natural resource managers need timely and usable data and tools in order to understand and predict changes to lakes and their biota. A previous Northeast CSC-funded project modeled lake temperatures to help state agencies in the Midwest understand trends in walleye and largemouth bass populations and predict lake-specific fish populations under future climate scenarios. These...

The purpose of this workshop is to identify important hydro- and ecological relationships that will affect the ability of floodplain managers to optimize their approaches to providing: 1) fish habitat; 2) wildlife habitat; 3) nutrient and sediment processing; and 4) flood regulation. The resulting conceptual model will guide future floodplain science, including the development of numerical simulation models of high interest relationships. Twenty participants at the workshop included science experts on each of the four floodplain functions, policy analysts, and floodplain managers faced with making optimization decisions. The workshop report will focus on relationships of greatest need of quantification and how they...
Conclusions: The amount of upstream impervious area affects downstream fish habitat quality, channel stability, and water quality. The use of riparian buffers can reduce the magnitude of urban impacts, however, they cannot fully mitigate the impacts of upstream development in the watershed. Threshold percentages of impervious areas , as well as the percentage of forest cover in a watershed appear to be the most effective indicators of watershed health. Thresholds/Learnings: Impervious areas should be kept at or below 10% of a watershed, and forest cover should be maintained at a minimum of 65% in order to effectively mitigate the impacts of urbanization and development on watersheds. Synopsis: This paper articulates...
The NFHAP Coastal Spatial Framework and Indicator Datasets consist of a geospatial base layer developed in ArcGIS, and associated data fields joined to the spatial framework. The Coastal Spatial Framework is a layer of 612 distinct polygons covering coastal areas of the Continental U.S. Polygons represent either coastal watersheds (land) or coastal waters (estuaries, inshore marine, offshore marine),and are classified into six regions and 22 nested subregions. Each polygon is assigned a unique code (UniqueID) to provide location reference for indicator data, and enable joins to separate data tables.s for information recorded in the Bibliography and Assessment tables. Key indicator data fields attributed to each...

Description of Work The main objective of this project is to identify locations within the St. Clair and Detroit Rivers that provide the best opportunities for remediation of fish spawning and nursery habitats, with the ultimate goal of enhancing native fish populations. Information about existing river habitat, current patterns, fish nursery areas, movements, spawning, and early life habitat requirements are being used in adaptive management models to identify areas suitable for creation or restoration of fish habitats. Physical and biological information are being coupled to show where and how habitat restoration will produce the strongest benefits to native fishes at multiple locations in the St. Clair and Detroit...

The National Fish Habitat Partnership (NFHP) Data System provides a means for the partnership to manage, access and visualize data products from across the partnership. Although components of the data system may change with evolving technologies, we plan to continue cataloging NFHP data products in USGS ScienceBase.
