Multibeam bathymetry in Peoria Lock, near Peoria, Illinois, September 19, 2019 Multibeam bathymetry in Peoria Lock, near Peoria, Illinois, September 19, 2019
The bathymetry (bottom elevation) of the downstream lock approach and lock chamber of Peoria Lock, near Peoria, Illinois, was surveyed on September 19, 2019. The data were collected using a multibeam echo-sounder mapping system (MBMS) with integrated inertial navigation solution (INS) mounted on a manned survey vessel. The raw data were processed and gridded to 0.5 meter using elevation...

Fluvial Egg Drift Simulator (FluEgg) Results for 240 Simulations of Bighead Carp Egg and Larval Drift in the Illinois River Fluvial Egg Drift Simulator (FluEgg) Results for 240 Simulations of Bighead Carp Egg and Larval Drift in the Illinois River
The Fluvial Egg Drift Simulator (FluEgg) estimates bighead, silver, and grass carp egg and larval drift in rivers using species-specific egg developmental data combined with user-supplied hydraulic inputs (Garcia and others, 2013; Domanski, 2020). This data release contains results from 240 FluEgg 4.1.0 simulations of bighead carp eggs in the Illinois River under steady flow conditions...
Water Level, Temperature, and Bathymetry of the Grand Calumet River, Indiana-Illinois, 2017 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...
Velocity measurements around the sill bubble curtain in Peoria Lock on the Illinois River, Illinois, September 17-18, 2019 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. An interagency study involving the U.S. Army Corps of Engineers, U.S. Fish and Wildlife...

In 2017, the U.S. Fish and Wildlife Service, U.S. Geological Survey, and U.S. Army Corps of Engineers undertook a large-scale interagency field study to determine the influence of commercial barge vessels on the efficacy of the Electric Dispersal Barrier System (EDBS) in the Chicago Sanitary and Ship Canal (CSSC) in preventing fish passage. This study included a series of trials in which...
USGS bathymetric and hydrodynamic survey of Lake Michigan nearshore near Ogden Dunes/Burns Harbor, Indiana 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.
