Summary

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, velocity surveys, and collected images of substrate in the Lower Meander Reach (RM 143 - 145.5). This data release contains bathymetry, velocity, and substrate data from surveys performed on the Kootenai River between 2012 and 2019 as part of the Substrate Enhancement [...]

Summary

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, velocity surveys, and collected images of substrate in the Lower Meander Reach (RM 143 - 145.5). This data release contains bathymetry, velocity, and substrate data from surveys performed on the Kootenai River between 2012 and 2019 as part of the Substrate Enhancement Pilot Project mapping (SEPP) under the Kootenai River Habitat Restoration Master Plan.

A once-per-year multibeam bathymetric mapping event was conducted at two discrete SEPP sites (Shorty's Island, and Myrtle Bend) to include ~10,000 linear feet of the Kootenai River Meander Reach. Bathymetric data were collected in the field using the Hypack software Hysweep. The bathymetric data were collected using a multibeam echosounder (MBE) system mounted on a USGS-owned and operated 25-foot jet boat research vessel. A complete description of standard data collection methods is described in Fosness (2013). These data were collected during surveys of velocity on the Kootenai River at Shorty's Island and Myrtle Bend. These survey operations were conducted June 4-9, 2017.

In 2017, bi-annual underwater videography surveys were conducted at the three discrete SEPP sites (Shorty’s Island, Myrtle Bend, and the Straight Reach). The first site (Shorty's Island) is located near River Mile 143.0; the second site (Myrtle Bend) is located near River Mile 145.5; the third site (Straight Reach) is located near River Mile 152.2. The three SEPP sites were surveyed in June, representative of peak-freshet conditions, and again in September, representative of pre-FRM (Flood-Risk Management) conditions. SEPP underwater monitoring is intended to capture a qualitative snapshot of sediment embeddedness, scour, and deposition trends within the project implementation area. The data are summarized as a series of georeferenced photos along with a summary file containing spatial coordinates for each photo. These survey operations were conducted on June 28 and September 29, 2017.

Biological velocity mapping surveys were conducted to help support understanding and interpretation of biological monitoring results. Velocity mapping was coincident with the Idaho Fish and Game biological monitoring program at the constructed Shorty's and Myrtle substrate enhancement pilot project sites and other known spawning areas. Acoustic doppler current profiling (ADCP) data was collected to describe streamflow characteristics including total streamflow, velocity magnitude and secondary flow structure, and backscatter intensity at cross-sections at the Shortys Island on the Kootenai River. Each of the cross-sections consisted of transects or bank-to-bank coverage to obtain a representative velocity pattern. These data were collected during surveys of velocity on the Kootenai River at Shorty's Island. These survey operations were conducted on June 6, 2017.

Purpose

The purpose of this data release is to summarize all monitoring data collected at the SEPP sites (Shorty's Island and Myrtle Bend). These data include ~10,000 linear feet of the Kootenai River Meander Reach. The first site (Shorty's Island) is located near River Mile 143.0 and the second site (Myrtle Bend) is located near River Mile 145.5.
