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. 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.
