    dct:description """An Innerspace 456 single-beam echosounder in conjunction with a Trimble® differential Global 
Positioning System (DGPS), HYPACK® navigation software, and Ashtech Z-Xtreme and 
Trimble® R8 Global Navigation Satellite System (GNSS) receivers was used to survey 7 
chutes and 3 backwaters on the Missouri River yearly from 2011-13. These chutes and 
backwaters are located on the Missouri River between Newcastle, Nebraska and Rulo, 
Nebraska in the States of Nebraska, Iowa, and Missouri.  Surveys of chutes consisted 
of topographic and bathymetric data collected along transects spaced 30.48 m apart 
from high bank to high bank.  Surveys of backwaters consisted of topographic and 
bathymetric data collected along a transect grid of 76.2 m spacing. The data were 
collected by the U.S. Geological Survey in cooperation with the U.S. Army Corps 
of Engineers (USACE) Omaha District as part of the Missouri River Habitat 
Assessment and Monitoring Program.""" ;
