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. The data release also contains the hydraulic inputs used in the FluEgg simulations and a KML file of the centerline that represents the model domain. FluEgg simulations were run for all combinations of four spawning locations, six water temperatures, and ten steady flow conditions. Each simulation included 5,000 bighead carp eggs,...
The USGS developed the second in a series of informative spatial distribution datasets of submersed aquatic vegetation (SAV) in Lake Erie. The second dataset was developed by object-based image analysis of high-resolution imagery (US waters < 6 meters deep) collected during peak biomass in 2018 to allow assessments of changes in SAV distribution. Assessing SAV abundance may contribute to inform the long-term impacts of Grass Carp, Common Carp, eutrophication, wind fetch and sedimentation on vegetation communities throughout Lake Erie and the impact these stressors may have on other organisms in the ecosystem. These data may also help inform the deployment of toxic bait deployments targeting Grass Carp. Bait placement...

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). Hydraulic inputs for a series of FluEgg simulations were generated using a one-dimensional steady Hydrologic Engineering Center-River Analysis System (HEC-RAS) 5.0.7 model for the Illinois River between Marseilles Lock and Dam and the Mississippi River confluence near Grafton, Illinois (HEC-RAS, 2019). The HEC-RAS model was developed by combining four individual HEC-RAS models obtained from the U.S. Army Corps of Engineers Rock Island District (U.S. Army Corps of Engineers...

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 Service, and the U.S. Geological Survey is aimed at assessing this potential (Asian Carp Regional Coordinating Committee, 2019). As part of this effort, on September 17 and 18, 2019, the U.S. Geological Survey measured water velocities around the bubble curtain system in Peoria Lock on the Illinois River. Peoria Lock has “sill...
