Description: Singlebeam echosounder data was collected in the nearshore of the Illinois coast of the Illinois Beach State Park in Zion, IL. These data were collected under contract for the Illinois Department of Natural Resources Coastal Management Program and with support from the Great Lake Restoration Initiative (GLRI) for the project identified as “Sustainable Nearshore Management Solutions to Prevent Critical Habitat Loss at Illinois Beach State Park, Phase 2”. The University of Illinois, under Agreement No. UOI-21-S-028 with Woolpert, Inc., assisted Woolpert, Inc. under its professional services agreement, Federal Contract No. EA-133C-16-CQ-0046 dated August 26, 2016 with the National Oceanic and Atmospheric Administration. The areas targeted for bathymetric measurements are paired with areas targeted for UAS (unoccupied aerial system) onshore photographic measurements. The bathymetric data were collected as part of a multi-year monitoring program to detect and measure lake-bottom change as it related to erosion of the lake bottom and longshore and offshore sand movement or transport.
