Abstract
The U.S. Geological Survey, in cooperation with the Bureau of Reclamation, began monitoring the Yellowstone River fish bypass channel according to the specifications of the Lower Yellowstone Adaptive Management and Monitoring Plan. The fish bypass channel was constructed to provide upstream migrating fish with a route around a diversion dam. The objective of this study is to monitor the physical and hydraulic characteristics of the bypass channel, including flow split, minimum depth for the deepest continuous 30 cross sectional feet, and mean channel velocity. Data are collected through several sets of measurements within the bypass channel at varying times during the field season. Physical and hydraulic data collected during this study can be used to ensure the hydraulic design criteria of the bypass channel are being met.
This report presents the methods used to monitor the physical and hydraulic characteristics of the bypass channel. Examples of the types of data collected and summarized as part of this study are provided using three figures and one table. Data collected for this study are summarized and published in an accompanying U.S. Geological Survey data release. The monitoring data can be used by the cooperating agencies to help describe the preferred hydraulic conditions for Scaphirhynchus albus (Forbes and Richardson, 1905; pallid sturgeon) passage.
Introduction
The Bureau of Reclamation (Reclamation) Lower Yellowstone Project was authorized in 1902 and provides irrigation water for about 58,000 acres in eastern Montana and western North Dakota (Bureau of Reclamation, 2021). The project includes the Intake Diversion Dam (IDD; fig. 1), a 12-foot (ft) high, 700-ft long wood and stone structure extending across the Yellowstone River channel, which raises the river elevation so water can be diverted into the Lower Yellowstone Project Main Canal (fig. 1). The diverted water is used to irrigate crops such as sugar beets, alfalfa, wheat, barley, and rye; however, the IDD is also a partial or total barrier to the movement upstream or downstream of some fish species and has been hypothesized to be a limitation to the recovery of the endangered Scaphirhynchus albus (Forbes and Richardson, 1905; pallid sturgeon; U.S. Fish and Wildlife Service, 2014). Monitoring of pallid sturgeon has indicated that these fish do not migrate beyond the IDD, and it is thought that the unimpeded river distance between the IDD and downstream reservoirs is not enough to allow free embryos of pallid sturgeon to naturally drift and mature (Bureau of Reclamation, 2021).
In 2019, construction began on a 2.1-mile-long bypass channel around the IDD (fig. 1) with the intention of allowing passage of pallid sturgeon and other fish. During construction of the bypass channel, Reclamation, in coordination with the U.S. Army Corps of Engineers and U.S. Fish and Wildlife Service, updated the Lower Yellowstone Adaptive Management and Monitoring Plan (Bureau of Reclamation, 2021) to specify monitoring criteria for the bypass channel. These criteria include the following:
-
1. Acoustic Doppler current profilers (ADCPs) are used to monitor the physical and hydraulic characteristics of the bypass channel at 14 permanent and 6 random cross sections, with potential for additional cross sections as needed.
-
2. Several sets of ADCP measurements are made at different times during the field season (April 1–October 31); each set of measurements includes all 20 cross sections measured on the same day and at the same streamflow for consistency.
-
3. The cross sections are measured at least twice during each of the following flow conditions:
In the spring of 2022, the U.S. Geological Survey (USGS), in cooperation with Reclamation, began monitoring the bypass channel according to the specifications of the Adaptive Management and Monitoring Plan. This report summarizes the general methods used by the USGS to monitor the physical and hydraulic characteristics of the bypass channel.
Purpose and Scope
The purpose of this report is to present methods used by the USGS to monitor hydraulic conditions in the bypass channel around the IDD on the Yellowstone River near Intake, Montana. Monitoring by the USGS began in 2022. Data collected from the 2022 and 2023 monitoring surveys are summarized and published in an accompanying USGS data release (Stephens and Siefken, 2024). This data release is planned to be updated annually as future data are collected. Data from the 2022 and 2023 monitoring surveys are used herein to illustrate how streamflow, channel geometry, and velocity data are collected and summarized in the data release.
Methods
Scientists and engineers use a variety of terms to describe characteristics of a river channel and its streamflow. In this report, the term “bathymetry” refers to the shape (topography) of a stream channel under the water surface and the term “hydraulics” refers to physical attributes of water flow in a stream channel. For monitoring cross sections in the bypass channel and the mainstem Yellowstone River, streamflow and water velocity are the primary measures used herein to describe hydraulic conditions; channel area, width, and depth are the primary measures used herein to describe channel bathymetry.
Acoustic Doppler Current Profiler Measurements
ADCPs were the primary instruments used to measure channel bathymetry and hydraulic conditions (Stephens and Siefken, 2024). ADCPs emit sound into the water column to measure water velocity via the Doppler effect (Mueller and others, 2013). The sound frequency emitted is dependent on the make and model of the ADCP, and different ADCP instruments are often designed for use in different river conditions (such as different depth, velocity, and clarity). Modern ADCP instruments can often measure velocity and direction of flow at multiple depths within the water column. These data are commonly averaged and binned over some user-defined width and depth interval.
ADCP measurements are typically made by suspending the instrument into the top of the water column and moving it across a span of the river channel in one or more passes perpendicular to the primary flow direction. Because channel hydraulic conditions are always changing, several passes are often made, and the measurements are postprocessed to produce an average of the conditions observed from each pass (Mueller and others, 2013). Additional details on methods used by the USGS to make ADCP measurements are provided in Mueller and others (2013). The USGS also uses a variety of software tools to postprocess ADCP measurement data including QRev (Mueller, 2016), RiverSurveyor LIVE (RSL; Xylem, 2023), and the Velocity Mapping Toolbox (VMT; Parsons and others, 2013). The end product is a rich dataset quantifying the shape of the channel and the spatial variation in flow velocity and direction at the channel cross section.
Cross Sections
ADCP measurements were made at the 14 permanent cross sections and 6 random cross sections. USGS station identifiers (table 1) were established for each cross section in the USGS National Water Information System (U.S. Geological Survey, 2023). The locations of the cross sections were preprogrammed as line features into a controller for a real-time kinematic global navigation satellite system (RTK–GNSS; fig. 2). This controller was then used to guide the location and direction of ADCP transect measurements at each cross section. Typical ADCP cross section measurements consisted of at least four passes and as many as six passes.

Velocity
Channel velocity characteristics are quantified and summarized using a combination of summary statistics and graphical depictions (Stephens and Siefken, 2024). The mean cross sectional water velocity (depth averaged velocity, table 1) of each surveyed cross section in the bypass channel and at the entrance and exit of the channel is determined from the QRev software as an average of all passes collected at each section. The VMT software was used to process RSL Microsoft Access table files and produce a heat map showing the average shape of the channel and spatial distribution of water velocities at each cross section (fig. 2).
The RSL Microsoft Access table files were also used to produce water velocity stick plan maps (fig. 3) in ArcGIS (Esri, 2023). These maps depict a plan view of the average velocity magnitude and direction within horizontally spaced samples at individual cross sections. Horizontal spacing is determined by applying an averaging time in the VMT Geographic Information System Export Tool. The averaging time to obtain 12–15 velocity vectors varies from survey to survey. The velocity vector sticks are useful for identifying the locations of the channel thalweg and changes in channel flow direction when compared with other surveys.
Streamflow
Streamflow (table 1) was computed for all surveyed cross sections except for those surveyed near the bypass channel entrance and exit. Streamflow was computed by postprocessing ADCP pass data in the QRev software (Mueller, 2016). The QRev software produces a final estimate of mean streamflow, as well as a measure of the uncertainty of the mean, depicted as the estimated 95-percent uncertainty. The estimated 95-percent uncertainty in the QRev software combines the random uncertainty, invalid data uncertainty, edge Q (cross section edge streamflow) uncertainty, extrapolation uncertainty, moving-bed test uncertainty, and systematic uncertainty (Mueller, 2016).
Flow Split
Flow split (table 1) was calculated as a percentage of the bypass channel streamflow to the total Yellowstone River streamflow. Total Yellowstone River streamflow was determined by the ADCP measurements collected at permanent cross section 14 at Yellowstone River mile 74 (Stephens and Siefken, 2024; fig. 3). The bypass channel streamflow was determined at the seasonal USGS streamgage located in the bypass channel (Yellowstone River fish bypass channel near Intake, Mont.; USGS station 06328495; fig. 1; U.S. Geological Survey, 2023) using the computed unit discharge value closest to the mean time of the measurement collected at Yellowstone River mile 74.
Bathymetry
The minimum depth (depth, table 1) for the deepest continuous 30-ft-wide stretch of surveyed cross section was determined from the most representative transect using the VMT Geographic Information System Export Tool with no averaging (Mueller, 2016) for each cross section. An algorithm was created using the R programming language (version 4.3.1; R Core Team, 2023) to determine the minimum depth for each 30-ft-wide section within the cross section starting with the first ADCP ensemble on the left bank. Four to six transects were collected with the ADCP at each cross section, each of which likely contains some random error; therefore, the representative transect used to determine bathymetry parameters is the transect that best represents the channel shape and velocity distribution as determined by the operator.
Water Surface Elevation
Water surface elevation (table 1) is the reference elevation for channel bathymetry measured at each cross section. This elevation is defined as the height of the water surface relative to the North American Vertical Datum of 1988. The water surface elevation for each cross section was determined by obtaining global positioning system (GPS) measurements with a survey rod along the edge of water or by using the height of the GPS antenna above the water surface elevation when using the GPS for ADCP navigation. The RTK–GNSS was used following USGS GPS survey techniques outlined in Rydlund and Densmore (2012). Control point 19, established by Reclamation, was used as vertical control for the RTK–GNSS surveys. All surveys were done using GEOID09 with Montana Federal Information Processing Standard 2500 State Plane coordinate projection.
Summary
In the spring of 2022, the U.S. Geological Survey, in cooperation with the Bureau of Reclamation, began monitoring the Yellowstone River fish bypass channel according to the specifications of the Adaptive Management and Monitoring Plan. The fish bypass channel was constructed to provide upstream migrating fish with a route around a diversion dam. The objective of this study is to monitor the physical and hydraulic characteristics of the bypass channel, including flow split, minimum depth for the deepest continuous 30 cross sectional feet, and the mean channel velocity. Data are collected through several sets of measurements at different times during the field season (April 1 to October 31). These data can be used to ensure that the hydraulic design criteria of the bypass channel are being met.
This report describes the methods used to monitor the physical and hydraulic characteristics of the bypass channel at 14 permanent and 6 random cross sections. Examples of the types of data collected and summarized for this study are described in the report, including a water velocity heat map profile, a georeferenced water velocity stick map, and a summary table of the hydraulic properties determined at all permanent and random cross sections. Data collected for this study are summarized and published in an accompanying U.S. Geological Survey data release. The monitoring data can be used by the cooperating agencies to help correlate hydraulic characteristics of the bypass channel to Scaphirhynchus albus (Forbes and Richardson, 1905; pallid sturgeon) passage.
