Summary

The U.S. Geological Survey (USGS) in cooperation with the U.S. Army Corps of Engineers (USACE) did a bathymetric survey of the lower reach of the Maumelle River upstream of Lake Maumelle, near Little Rock, Arkansas, from July 9—11, 2019. Channel bed elevations (thalweg) were collected to support a USACE modeling effort on a 5-mile reach of the Maumelle River. In parts of the reach where the water was partially impounded, depth data were collected using an acoustic Doppler current profiler (ADCP) coupled with a survey-grade deferentially corrected global positioning system (GPS) receiver. Depth data were converted to channel bed elevation data by subtracting the depth value from the GPS derived water-surface elevation. Additional [...]
