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 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.

Between 2011 and 2018, numerous restoration treatments were constructed in the Straight and Braided 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 hydraulic model archive 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 with the topographic surfaces for 2011, 2020, and 2022, producing a total of nine unique simulations. Flow depths, depth-averaged velocity, and area associated with each model grid node were exported for each simulation. Measured suspended sediment concentrations and estimated tributary discharge The potential impact of the construction projects on suspended sediment entrainment within the Braided Reach was investigated through analysis of measured suspended sediment concentration (SSC) at two US Geological Survey (USGS) streamgages that bracket the study reach. To test for temporal trends in measured SSC (total, fine, and sand fractions) at both streamgages, multiple linear regression models were developed with SSC as a function of the independent variables time and estimated discharge from tributaries between Libby Dam and the study reach. Tributary discharge was used rather than Kootenai River discharge because Libby Dam has high sediment trapping efficiency and SSC in the Braided and Straight Reaches is driven primarily by tributaries between Libby Dam and the Below Moyie site.

Endangered pallid sturgeon (Scaphirhynchus albus) spawning habitats were mapped on the Tongue River near Miles, City Montana June in 2023 and 2024. Data quantify the physical characteristics of the river channel and flow; depth, velocity and habitat assessments using single-beam sonar, acoustic Doppler current profilers (ADCPs) in 2023 and single-beam sonar in 2024. Real-time kinematic Global Navigation Satellite Systems (GNSS) through a base station were used for positioning in 2023 and a Real-time GNSS correction network was used in 2024. In 2023 depths and velocities were mapped in a 1.6 kilometer long reach used by pallid sturgeon with transects that had a 15-meter spacing. In 2024 we surveyed a longitudinal profile of depth, water surface elevation, and bed elevation for 30.3 kilometers from just below Twelve Mile Dam to just upstream from the confluence with the Yellowstone River. Elevation control in 2024 used a real time virtual reference station correction subscription that utilized satellite-based elevation corrections.This dataset includes: Maps of depth and velocity for a 1.6 km long reach in 2023, raw ADCP points used to generate depth and velocity maps, raw ASCII ADCP data from transects used to generate depth and velocity maps, and a longitudinal bed and water surface profile of a 30.3 km long reach surveyed on 6/29/2024.

Acoustic telemetry is an effective tool for the study of fish survivorship and habitat use. Fish are tagged with acoustic tags and presence data is collected with stationary receivers. This data set contains a total of 69 hatchery tagged juvenile Lake Sturgeon released into the Genesee River, NY in the Fall of 2019 and 2020, along with data for 30 sub-adult Lake Sturgeon field tagged in the summer of 2019 and fall 2020. The juvenile Lake Sturgeon data includes release date, location, PIT tag number, acoustic tag number, length, weight, year class, and sex. The sub-adult Lake Sturgeon data includes capture date, location, PIT Tag, acoustic tag, length, weight, girth, year class, and sex. Telemetry detection data was funded and collected by the U.S. Fish and Wildlife Service (USFWS) and State University of New York (SUNY)-Brockport.

Overview The Central Valley Project Improvement Act (CVPIA) funds habitat improvement work and associated monitoring in the Central Valley of California to increase salmonid populations in furtherance of meeting CVPIA fish doubling goals. This data package contains three datasets for larval White Sturgeon (Acipenser transmontanus) monitoring in the San Joaquin River (SJR) conducted by the US Fish and Wildlife Service, Lodi Fish and Wildlife Office. SJR_Larval_WST_Set Data: This dataset contains data on an experimental sampling program using boat-mounted drift nets (D-frame nets), a large drift net attached to a stationary pontoon (pontoon net), and otter trawls to catch larval White Sturgeon in the San Joaquin River. Sets were made at targeted locations from March-July in 2013, 2015, 2016, and 2017. A total of ten White Sturgeon were captured in 2016 and 11 in 2017, all with D-frame driftnets. SJR_Larval_WST_Catch Data: This dataset contains data for individual fish caught in the San Joaquin River. Species and fork length were recorded for most individuals. SJR_Fish_Taxonomy Data: This dataset contains data for fish codes used in the Catch datafile. For each species that was captured, the Species codes are listed with the corresponding Interagency Ecological Program code, common name, taxonomy (Phylum, Class, Order, Family, Genus, and Species), and whether or not the species is native to the region.
