Kootenai River Substrate Enhancement Pilot Projects near Bonners Ferry, ID (ver. 3.0, January 2023)

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. 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. Summary of Substrate Enhancement Pilot Project (SEPP) data, Water Years 2012-2019 2012 - velocity only at Shorty's Island. 2013 - bathymetry and velocity at Myrtle Bend; bathymetry only at Shorty's Island. 2015 - bathymetry (x2) and substrate at Myrtle Bend; bathymetry (x2) and substrate at Shorty's Island. 2016 - bathymetry, substrate (x2), and velocity at Myrtle Bend; bathymetry, substrate (x2), and velocity at Shorty's Island. 2017 - bathymetry, substrate (x2), and velocity at Myrtle Bend; bathymetry, substrate (x2), and velocity at Shorty's Island; substrate (x2) and velocity at the Straight Reach. 2019 - substrate at Myrtle Bend; substrate at Shorty's Island; substrate and velocity at the Straight Reach.
