Maintaining the native prairie lands of the Northern Great Plains (NGP), which provide an important habitat for declining grassland species, requires anticipating the effects of increasing atmospheric carbon dioxide (CO2) concentrations and climate change on the region’s vegetation. Specifically, climate change threatens NGP grasslands by increasing the potential encroachment of native woody species into areas where they were previously only present in minor numbers. This project used a dynamic vegetation model to simulate vegetation type (grassland, shrubland, woodland, and forest) for the NGP for a range of projected future climates and relevant management scenarios. Comparing results of these simulations illustrates...

The USGS Wyoming-Montana Water Science Center (WY–MT WSC) completed a report (Sando and McCarthy, 2018) documenting methods for peak-flow frequency analysis following implementation of the Bulletin 17C guidelines (England and others, 2019). The methods are used to provide estimates of peak-flow quantiles for 66.7-, 50-, 42.9-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabilities (AEPs) for selected USGS streamgages. This data release presents peak-flow frequency analyses for selected streamgages in Carter, Custer, Fallon, Powder River, and Prairie Counties, and the Powder River Basin, based on data through water year 2022, using methods described by Sando and McCarthy (2018).

This layer was created from the Ecological Systems Map (ESM+, also called DSL Land) to highlight a number of habitat types specifically. We used the Summarize Zones function in ArcMap along with the Protected Areas Dataset and the ESM+ layer to identify the extent and protection status of all ecological systems (macrogroup level) across the 4 northeast states of NY, VT, NH, and ME. We also used information on potential habitats for Regional Species of Greatest Conservation Need (RSGCN) for these 4 states from a prior crosswalk of ESM+ macrogroups with Natureserve habitat types completed by Glennon and Curran (2013). The following habitat types were identified as (1) making up less than 10% of NYS (most are <...

The two-dimensional (2D) hydraulic flow model International River Interface Cooperative with the Flow and Sediment Transport with Morphological Evolution of Channels solver (iRIC FaSTMECH) was used to investigate the impacts of habitat restoration treatments on hydraulic conditions in the Braided and Straight Reaches of the Kootenai River near Bonners Ferry, ID. The treatments were constructed between 2012 and 2018. Topographic surfaces from 2011, 2020, and 2022 were used to simulate hydraulic conditions before and after restoration treatments were built. Three different flow conditions (discharge and downstream water surface elevation) from the 2020 spring snowmelt hydrograph were simulated on a 5-meter model grid...

White sturgeon fine-scale habitat model archive, Kootenai River near Bonners Ferry, Idaho, 2017-2022
The two-dimensional (2D) hydraulic flow model iRIC FaSTMECH (Nelson, 2003) was used to simulate hydraulic conditions in the Kootenai River near Bonners Ferry, ID during white sturgeon spawning season during 2017, 2018, 2019, 2020, and 2022. Details on model development and calibration in FaSTMECH can be found in other studies (Dudunake and others, in progress; Barton and others, 2005; Barton and others, 2007; Logan and others, 2011; McDonald and others, 2016; McDonald and Nelson, 2018; McDonald and Nelson, 2020). Simulations were run with a 1-meter grid and six-hour time-steps from April 25 to August 15 of 2017, 2018, 2019, 2020, and 2022. Simulated depths and depth-averaged velocities were exported.

Kootenai river hydraulic conditions were simulated using the iRIC FaSTMECH two-dimensional hydraulic flow model (Nelson, 2003). In addition to this study, FaSTMECH 2D flow models have been developed for numerous Kootenai River studies dating back to 2005. The methods used to develop, calibrate, and simulate FaSTMECH 2D flow models are described at length in multiple previous studies (Fosness and Dudunake, in press; Barton and others, 2005; Barton and others, 2007; Logan and others, 2011; McDonald and others, 2016; McDonald and Nelson, 2018; McDonald and Nelson, 2020). Model simulations were combined with white sturgeon telemetry data to explain fish positions with respect to selected depths and depth-averaged velocity.

The U.S. Geological Survey (USGS) Central Midwest Water Science Center (CMWSC) completed a report (Over and others, 2023) documenting methods for peak-flow frequency analysis in Illinois following Bulletin 17C guidelines. The methods are used to provide estimates of peak-flow quantiles for 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabilities (AEPs) for selected USGS streamgages. This data release presents peak-flow frequency analyses for selected streamgages in Illinois, Indiana, and Wisconsin, based on data through water year 2017 (a water year is the period from October 1 to September 30 and is designated by the year in which it ends; for example, water year 2017 was from October 1,...

Between 2011 and 2018, numerous restoration treatments were constructed in the Straight and Braided and Straight Reaches of the Kootenai River in northern Idaho as part of the Kootenai River Habitat Restoration Project. Led by the Kootenai Tribe of Idaho, the project aimed to address a range of anthropogenic impacts inhibiting natural recruitment of the critically endangered Kootenai River white sturgeon (Acipenser transmontanus) and other native fish species. This data release contains information for two analyses used to assess the impact of the restoration treatments on channel morphology, flow depths, flow velocity, the extent of pools, and suspended sediment transport within the study reach. Two-dimensional...
Groundwater potentiometric-surface contours for spring 2022 (April 4 to 8, 2022) and autumn 2022 (October 30 to November 4, 2022) were created for the alluvial aquifer in Big Lost River Valley. The well numbers and station names used to create the potentiometric-surface contours and groundwater-level change maps are provided in this data release. The location, depth to water, and potentiometric-surface altitude for these wells can be accessed on USGS National Water Information System (NWIS) or Idaho Department of Water Resources (IDWR) groundwater portal. The interpreted 20-foot contours of the potentiometric-surface are also provided in this data release. The contours are referenced to the North American Vertical...
Ecological regions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across international, national, province and state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas.A Roman numeral hierarchical scheme has been adopted for different levels for ecological regions. Level I is the coarsest level, dividing North America...
