The USGS, in cooperation with the U.S. Bureau of Reclamation, surveyed the bathymetry within an area of about 500 acres of American Falls Reservoir between River Miles 713 and 714 during the week of August 6-8, 2019. The bathymetric survey provided high resolution detail of a proposed treatment area for an aeration system that is being developed to support water quality during the American Falls spillway concrete repair project and possibly thereafter. The Water Quality Restoration Plan detailing this effort is an appendix of the of the Final Environmental Assessment (EA) in conjunction with the National Environmental Policy Act (NEPA) compliance process.
