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...

This shapefile contains fish habitat condition index (HCI) scores as well as specific disturbance indices for 6th level Hydrologic Unit Code (HUC12) watersheds of the Watershed Boundary Dataset. The source datasets compiled and attributed to spatial units were identified as being: (1) meaningful for assessing fluvial fish habitat; (2) consistent across the entire study area in the way that they were assembled; (3) broadly representative of conditions in the past 10 years, and (4) of sufficient spatial resolution that they could be used to make valid comparisons among HUC12 units. In this data set, variable summaries are linked to HUC12 watersheds developed for the Watershed Boundary Dataset downloaded on March 18,...

This shapefile contains cumulative fish habitat condition index (HCI) scores as well as specific disturbance indices for local and network catchments of Southeast Alaska. Catchments were created in support of Jared Ross's Master’s thesis. The source datasets compiled and attributed to spatial units were identified as being: (1) meaningful for assessing fluvial fish habitat; (2) consistent across the entire study area in the way that they were assembled; (3) broadly representative of conditions in the past 10 years, and (4) of sufficient spatial resolution that they could be used to make valid comparisons among local catchment units.

This CSV file contains cumulative fish habitat condition index (HCI) scores generated for river reaches of the conterminous United States as well as indices generated specifically for four spatial units including local and network catchments and 90 m local and network buffers of river reaches. Note that the cumulative HCI score is determined from limiting index scores generated for the four spatial units listed above. Detailed methods for calculating cumulative fish habitat condition index scores as well as the indices for each spatial extent can be found on the following website: http://assessment.fishhabitat.org/: The variables used to create indices in catchments vs. buffers differ due to differences in resolution...

This CSV file contains 21 dam metrics representing stream fragmentation and flow alteration for nearly 2.3 million stream reaches in the conterminous USA. Dam metrics fall into four main categories: segment-based, count and density, distance-based, and cumulative reservoir storage (described below). These data were developed using spatially verified large dam locations (n=49,468) primarily from the National Anthropogenic Barrier Dataset (NABD) that were spatially linked to the National Hydrography Dataset Plus version 1 (NHDPlusV1). These dam metrics have been summarized using the unique identifier field native to the NHDPlusV1 (COMID) which can be used to join this table to spatial layers and data tables of the...

This CSV file contains landscape factors representing anthropogenic disturbances to stream habitats summarized within 6th level Hydrologic Unit Code (HUC12) watersheds of the Watershed Boundary Dataset. The source datasets compiled and attributed to spatial units were identified as being: (1) meaningful for assessing fluvial fish habitat; (2) consistent across the entire study area in the way that they were assembled; (3) broadly representative of conditions in the past 10 years, and (4) of sufficient spatial resolution that they could be used to make valid comparisons among local catchment units. Variables summarized at the HUC12 scale include measures of anthropogenic land uses, population density, roads, dams,...

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....

This geodatabase contains 90 meter buffers of streams within the National Hydrography Dataset Plus Version 1 (NHDPlusV1). These buffers were developed by converting NHDPlusV1 flowlines to a 30m grid, then running a euclidean allocation function in ArcPy to generate buffer zones. For flowlines representing artificial paths within NHD area river polygons, buffers extend from the outside edges ("banks") of the polygon outward. The source code for buffer development can be found at https://github.com/ArthurCooper/NFHP-Buffer-Code.

This shapefile contains cumulative fish habitat condition index (HCI) scores and specific disturbance indices for local and network stream catchments as well as the downstream main channel catchment of perennial and intermittent streams reaches of the five main island of Hawai'i. In this dataset indices are linked to the Hawaii Fish Habitat Partnership (HFHP) stream layer (Tingley et al. in prep) which is a modified version of the 1:24,000 National Hydrography Dataset. It includes 11,436 intermittent and perennial stream reaches across the five main Hawaiian Islands (Hawai’i, Maui, Moloka’i, O’ahu, Kaua’i). Catchment attributes are available for both local catchments (defined as the land area draining directly to...
