Summary

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. An Innerspace 456 single-beam echosounder in conjunction with a Trimble® differential Global Positioning System (DGPS) and HYPACK® navigation software, and Ashtech Z-Xtreme and Trimble® R8 GNSS receivers was used to survey 7 chutes and 3 backwaters on the Missouri River yearly from 2011-13.

Purpose

The purpose of collecting this survey data was to provide yearly measurements of the chutes and backwaters for the U.S. Army Corps of Engineers to calculate yearly geomorphic change to understand chute and backwater evolution. This data is also used by the U.S. Army Corps of Engineers for measuring the amount of shallow water habitat available for endangered species for compliance with the "2000 Biological Opinion" and the "2003 Amendment to the Biological Opinion" on the Missouri River as part of the Habitat Assessment and Monitoring Program.
