Active Water Rights of Montana. The data consists of estimated locations of all the active recorded points of diversion and points of use in the water rights database. There are four separate spatial layers: Points of diversion, Points of Use, Points of Reservoirs, and Points of Use for Irrigation (a subset of Points of Use). The version of this data available at the State Library is updated on a weekly basis. For administrative purposes, the original version of all active water rights is given (i.e. Version ID = 1). If change of information about a particular water right has occurred over time, there will be an additional version of the water right, and depending on how many changes, there will only be one other...
All wetlands within the Wyoming Basin REA Project area including lake, riverine, or river wetland types compiled from National Wetlands Inventory data from the five states in the project area.
The Vista tool is used to create a Scenario of the habitat quality CAs affecting the North American Warm Desert Riparian Woodland, Shrubland, Mesquite Bosque and Stream CE and applies user-input Landscape Condition Model (LCM) scores to generate ESAs for each of the CEs. The LCM consists of Site Impact scores and impact Distances for each CA category. Site Impact scores are a value between 0 and 1 representing the impact of the CA on the relevant CEs. A score close to 1 indicates negligible or no impact from that CA. A score close to 0 indicates the highest possible impact, e.g. an interstate highway that makes the area in which it occurs completely unsuitable for the CE. Distances are set in meters and extend the...

NHD Open Water
Large and small connected lakes throughout the CYR study area support a rich biodiversity of aquatic organisms and represent important foraging and breeding habitat for fish, waterfowl, and shorebirds. Additionally, lakes provide important recreational opportunities and food resources for local residents (e.g., subsistence harvest of fish and wildlife). Small and large lakes were identified based on the definition used in Arp and Jones (2009) to differentiate small (less than 0.1 sq km) from medium and large lakes (greater than 0.1 km2). Lake connections, especially for smaller lakes, can vary greatly and change throughout the open-water season, with ephemeral connections commonly occurring during high flows in...
Landscape-level ecological value was based on length of perennial and ephemeral/intermittent streams within a 5th-level watershed assessed as the length of stream per area of watershed.
Two future climate change scenarios at a resolution of 0.5 degree latitude/longitude for the conterminous United States were used in the Vegetation Ecosystems Modelling Analysis Project (VEMAP): a moderately warm scenario produced by the general circulation model from the Hadley Climate Centre [Johns et al., 1997; Mitchell and Johns, 1997], HADCM2SUL (up to a 2.8oC increase in average annual U.S. temperature in 2100) and a warmer scenario (up to a 5.8oC increase in average annual U.S. temperature in 2100), CGCM1, from the Canadian Climate Center [Boer et al., 1999a, 1999b; Flato et al., 1999]. Both general circulation models (GCMs) included sulfate aerosols and a fully dynamic 3-D ocean. Both transient scenarios...
Compiled from National Hydrography point events point data where EventType is Dam for the Wyoming Basin REA project area. Dams within the Wyoming Basin were identifed for use in barrier determination and flow restrictions.
Relative effects of the co-occurrence of CAs and CEs are addressed in part by evaluating ecological status of CEs within a given assessment scenario (e.g., current conditions). The approach to evaluating ecological status was based on existing methods for gauging relative ecological integrity . “Ecological integrity” is variously defined as the ability of an ecological system to support and maintain a community of organisms that have the species composition, diversity, and functional organization comparable to those of natural habitats within the ecoregion. Therefore, one of the early tasks in the assessment was to characterize reference conditions for each CE, including natural composition, structure, and dynamic...

5th Code HUC reporting units for the Sonoran Desert Ecoregion Used as analytical reporting units for aquatic conservation elements.
Aquatic Development Index (ADI) for cutthroat streams in the Wyoming Basin REA project area. ADI scores are based on a ranked index of combined disturbances assessed at three scales: local catchment (LADI), aggregated upstream catchments (UADI) and averaged local and upstream catchment (ADI). The ADI quantifies the relative disturbance within a catchment for four disturbance variable classes: transportation (roads and railroads, area and number of crossings), energy and minerals (number of oil and gas wells, number of wind turbines, mine area), water (number of dams, number of surface diversions and length of 303d streams) and land use (agriculture, e.g. pasture and cropland, and urban land covers). ADI scores range...
This dataset depicts watersheds (HUC5) that contain observations of lowland leopard frogs more recent than 1980. Observations were derived from data Arizona Natural Heritage program (proprietary, cannot be shared with BLM or public).
This layer combines the USGS' "US Aquifer' data with the Colorado Decision Support Service's "Bedrock Aquifer" data. The CDSS' version of the San Luis Valley aquifer in South Central Colorado provides a greater level of spatial detail than the larger USGS aquifer dataset which includes the area of interest within Northern New Mexico/Taos Plateau. Therefore the Colorado portion of the San Luis Valley aquifer was removed from the USGS US Aquifer dateset and replaced and edge-matched with the polygon represention of the aquifer provided by CDSS Bedrock Aquifer polygon.
We used the length of sauger occupied streams as an index of patch size in streams situated in sixth-level watersheds with Aquatic Development Index scores less than 20 (relatively undeveloped). Stream segments were based on natural and anthropogenic barriers (dams) that restrict bi-directional movements among sauger populations.
Landscape-level ecological risk for cutthroat trout was based on Aquatic Development Index score, risk of low summer flow, and hybridization risk compiled into an overall index of conservation potential for each fifth-level watershed. To account for different spatial patterns of habitats (mainstems, headwaters, and lakes), we combined area ranks based on stream segment length and number of populations (based on counts of occupied segments and lakes) into an overall risk.
This dataset provides an estimate of water-based recreation travel corridors, based on a combination of wild and scenic rivers, and major rivers selected from NHD that were listed on the BLM rivers website. All reaches of these rivers were selected, as insufficient information exists to determine what segments may or may not be open to recreation. Other areas may be open to water-based recreation travel than are represented in this dataset.
Local Aquatic Development Index (LADI) for wetlands in the Wyoming Basin REA project area. ADI scores are based on a ranked index of combined disturbances assessed at the local catchment (LADI) scale. The LADI quantifies the relative disturbance within a catchment for four disturbance variable classes: transportation (roads and railroads, area and number of crossings), energy and minerals (number of oil and gas wells, number of wind turbines, mine area), water (number of dams, number of surface diversions and length of 303d streams) and land use (agriculture, e.g. pasture and cropland, and urban land covers). LADI scores range from 0 to 100 percent and were divided into seven classes for visualization purposes....
