Water Level, Temperature, and Bathymetry of the Grand Calumet River, Indiana-Illinois, 2017
The Grand Calumet River is located east of Chicago, Illinois and flows east to west across the Indiana-Illinois border to its confluence with the Little Calumet River. In 2017, a suite of water level, temperature, and bathymetric data were collected along the Grand Calumet River. Water level and water temperature were monitored continuously at five locations in the Grand Calumet River between late
Velocity measurements around the sill bubble curtain in Peoria Lock on the Illinois River, Illinois, September 17-18, 2019
Bubble curtain systems, also called "bubblers," are used in navigation locks to prevent the buildup of ice around the gates in the winter. It has been proposed that bubblers could potentially serve an additional purpose as a deterrent to the upstream movement of aquatic invasive species through locks.

USGS bathymetric and hydrodynamic survey of Lake Michigan nearshore near Ogden Dunes/Burns Harbor, Indiana
The US Army Corps of Engineers (USACE) is evaluating the placement of dredged material in the nearshore areas of Lake Michigan as a means to replenish sand at selected beaches. In order to elucidate the physical processes in the nearshore environment that transport and distribute sand to the beach, the USACE-Chicago District and the US Geological Survey (USGS) developed a plan for a beach nourishm
Bathymetric survey of Lake Calumet, Cook County, Illinois
The U.S. Geological Survey collected bathymetric data in Lake Calumet and a portion of the Calumet River in the vicinity of Lake Calumet to produce a bathymetric map. The bathymetric survey was made over 3 days (July 26, September 11, and November 7, 2012). Lake Calumet has become a focus area for Asian carp rapid-response efforts by state and federal agencies, and very little bathymetric data exi

Trolley Operated Automatic Discharge System (TOADS)—An automated system for horizontal profiling of water velocity and river discharge measurements
Hydroacoustics have revolutionized how the U.S. Geological Survey (USGS) measures streamflow by increasing the efficiency and quality of the measurement. However, the ability to determine the full range of streamflow at a streamflow-gaging station remains limited because in-person flow measurements still must be made by qualified personnel. As a result, streamflow during flood events typically is

Analysis of nearshore placement of sediments at Ogden Dunes, Indiana
The harbor structures/shoreline armoring on the southern Lake Michigan shoreline interrupt sand migration. Ogden Dunes, Indiana, and the nearby Indiana Dunes National Lakeshore observed shoreline erosion due to engineered structures associated with Burns Waterway Harbor, east of Ogden Dunes, impeding natural east to west sediment migration. To remedy this, USACE placed over 450,000 cubic meters, o
