Dudunake William P. Nuckoles Ezra I. Grey 2019 publication U.S. Geological Survey ScienceBase data release version 4.0 https://doi.org/10.5066/P9OC5QMH In 2009, the Kootenai Tribe of Idaho released and implemented the Kootenai River Habitat Restoration Master Plan. This plan aimed to restore, enhance, and maintain the Kootenai River habitat and landscape to support and sustain habitat conditions for aquatic species and animal populations. In support of these restoration efforts, the U.S. Geological Survey, in cooperation with the Kootenai Tribe of Idaho, conducted high-resolution multibeam echosounder bathymetric surveys as a baseline bathymetric monitoring survey on the Kootenai River near Bonners Ferry, Idaho. Three channel patterns or reaches exist in the study area: braided, meander, and a transitional zone connecting the braided and meander reaches. Bathymetric data were collected to: (1) survey unmapped portions of the Kootenai River; (2) re-survey portions of the Kootenai River to quantify changes in the channel; and (3) monitor aggradation and degradation of the channel bed at specific cross-sections within the braided reach and transitional zone. The bathymetric data will be used to update and verify flow models, calibrate and verify sediment transport modeling efforts, and aid in the biological assessment in support of the Kootenai River Habitat Restoration Master Plan. The data for each study reach were produced in LAZ format supported by most geospatial software. First release: December 2019 Revised: January 2023 (ver. 4.0) Baseline bathymetry data provide the initial high-resolution reach-scale multibeam bathymetric surveys on the Kootenai River starting in 2009. Baseline bathymetry data were collected in the Kootenai River extending from River Mile (RM) 186 (Troy, MT) downstream to the mouth of the Kootenai River (referred to as Kootenay River in Canada) at RM 76.5 (mouth of Kootenay River at Kootenay Lake). These bathymetry data generally include complete coverage for the braided, straight, and meander reaches of the Kootenai/Kootenay River and Deep Creek (Kootenai River tributary). 20090501 20220715 ground condition Complete As needed -116.58023454 -116.04476447 49.09119381 48.61614347 ISO 19115 Topic Category inlandWaters elevation location USGS Thesaurus topography bathymetry bathymetry measurement GPS measurement land surveying Multibeam sonar lidar digital elevation models spatial analysis geospatial analysis contouring geospatial datasets topographic maps sedimentation erosion none Hypack Hysweep USGS Metadata Identifier USGS:5dcf2a17e4b06957976275e3 Common geographic areas Pacific Northwest Kootenai-Pend Oreille-Spokane Kootenai Boundary Idaho Bonners Ferry Montana MT Troy United States Geographic Names Information System (GNIS) USA Canada Kootenai River Kootenay River Idaho ID Montana MT British Columbia Bonners Ferry Creston None These data are not intended for navigational purposes.

HYPACK, Inc. Quality assurance (QA) and quality control (QC) are critical with multibeam echosounder (MBES) surveys to maintain the highest degree of accuracy. Qualitative notes documenting anything that might affect the quality of the data, such as wave action, macrophyte growth, poor GPS quality, and any other observation that could degrade the bathymetric data were recorded in the daily field log. Prior to and during the survey, unique tasks were conducted at specified intervals to prepare the MBES system for bathymetric surveying, but also to describe the total estimated error within the system. Quality-assurance elements were developed following the input requirements of the Total Propagated Uncertainty (TPU) feature built into Hypack software. The TPU required a description of the general, environmental, and sensor settings to best estimate the total error potential in the survey data. Daily checks were made to ensure the GPS elevation by the MBES was verified with local horizontal and vertical benchmark data. Physical offsets were measured to reflect the correct geometric alignment of the equipment and to ensure proper translation for the MBES data solutions. A patch test ensured the MBES system was correctly offset and calibrated. The offsets from the patch test were applied to the system prior to the surveys on the Kootenai River. After the last survey, a performance test (also referred to as a beam angle check) provided quality control by quantifying the accuracy of the MBES. The performance test compared a set of standard survey data against a known reference surface. The performance test for the Kootenai River bathymetric surveys was conducted downstream from the Tribal Hatchery boat dock on the Kootenai River near Bonners Ferry, ID. The output from the performance test includes a summary of how the accuracy of the X,Y, and Z data are distributed through the swath of the MBES. Data uncertainty generally increases with beam angle (from the center (NADIR) beam). A complete description of the process used for quality control and quality assurance is provided in Fosness (2013). 110 river miles of bathymetry data were collected in the meander, straight, and braided reach during a 13 year period extending from 5/01/2009 - 07/15/2022. These bathymetric data describe baseline conditions, supplemental data that describe pre- and post-treatment conditions, and cross-section surveys used to monitor erosion and aggradation. Edited raw data are presented in a LAZ (a compressed version of LAS) format in the most raw form so that it can be used in various types of geospatial software applications. Gaps may exist in the coverage due to extremely shallow areas, erroneous data spikes, macrophyte growth, in-stream hazards (submerged trees), or non-kinematic positioning. Missing data largely existed in shallow areas that were inaccessible, near edges where macrophyte growth was prevalent along with submerged trees or other anthropogenic obstructions (docks, etc). The average horizontal uncertainty of the multibeam system was minimized as part of the patch test process. The horizontal accuracy of the postprocessed data is reported in individual metadata records. The average vertical uncertainty of the multibeam system is variable depending on depth and beam angle. The vertical accuracy of the postprocessed data is reported in individual metadata records. The equipment used to conduct the bathymetric survey included an Odom Hydrographic Systems ES-3 multibeam echosounder; an International Industries™ DSM-10 TSS dynamic motion reference unit (roll, pitch, yaw); and an Odom DIGIBAR Pro profiling sound velocimeter to provide continuous near-surface sound velocity data. A Hemisphere™ VS110 heading and position receiver using two GPS antennas mounted over the echo sounder transducer provided a precise heading. A more detailed description of the equipment used for the bathymetric survey is described in Fosness (2013). Horizontal and vertical positioning was accomplished using an RTK-GPS receiver mounted directly above the MBES and radio linked to a static base-station receiver using a GPS antenna positioned over one of the three temporary benchmarks. A real-time network (RTN) was used for position corrections when cellphone coverage was available. Bathymetry data were collected using HYPACK® software’s HYSWEEP® Survey (HYPACK, Inc., 2022). Starting in 2020, bathymetric data were collected using a WBMS (wide-band multibeam sonar) system. This system consists of a multibeam echosounder, an inertial navigation system (INS), and data acquisition computer. The echosounding component was a 400 kHz Norbit integrated wideband multibeam system (iWBMS) capable of projecting 512 beams spanning a max of 210 degree swath (width of coverage) and beam widths of only 0.9 degrees. An Applanix based inertial navigation system accounted for heave, pitch, and roll of the vessel. One AML Oceanographic Base-X sound velocity probe (velocimeters) was used to profile the speed of sound underwater. One velocimeter was mounted and operated real-time near the MBES to account for spatial change in the surface speed of underwater sound. Two Trimble 540AP antenna GPS receivers mounted over the MBES was linked to a base station to provide real-time horizontal and vertical positioning. These data were transmitted via Ethernet data link to and from a small sonar interface unit (SIU) to transmit control commands to the sonar, receive the sonar records, and receive heading data for the iWBMS. Bathymetric data were collected using HYPACK® software’s HYSWEEP® Survey or Norbit Data Collection Tool (DCT) along longitudinal survey lines spaced such that proper overlap between survey data was achieved. 20090501 The raw data were then edited using Hypack MBMAX software. All raw data were initially filtered to exclude the outer multibeam swath soundings to remove erroneous data. These data were out of tolerance and therefore excluded from the final data. Areas of missing data occurred within the dataset due to erroneous data spikes, macrophyte growth, submerged debris, or non-kinematic positioning. The data were reduced to the median value and output with a data density of 1 point per square foot. A complete description of standard data editing methods is described in Fosness (2013). 20090501 The edited (ASCII XYZ) data were converted to LAZ format. 20220820 Revision (Version 4.0) uploaded to ScienceBase Data Release.
