Long-term monitoring data of geomorphic, hydrological, and biological characteristics of landscapes. This information provides an effective means of relating observed change to possible causes of the change. Identification of changes in basin characteristics, especially in arid areas where the response to altered climate or land use is generally rapid and readily apparent, might provide the initial direct indications that factors such as global warming and cultural impacts have affected the environment. The Vigil Network provides an opportunity for earth and life scientists to participate in a systematic monitoring effort to detect landscape changes over time, and to relate such changes to possible causes. This...

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,...

A variety of new technologies are being evaluated to mitigate the spread of invasive carps from the Illinois River to the Great Lakes. In 2022, the U.S. Army Corps of Engineers, U.S. Fish and Wildlife Service, and U.S. Geological Survey undertook a field-scale interagency study to determine the efficacy of an Automated Barge Clearing Deterrent (ABCD) in flushing live fish away from commercial barge vessels entering Peoria Lock on the Illinois River. The ABCD is a forced air manifold system that is placed at the channel bed to create a longitudinal array of bubble plumes. In support of this study, the bathymetry (bottom elevation) of the downstream approach to Peoria Lock, near Peoria, Illinois, was surveyed several...

The U.S. Geological Survey (USGS) monitors water surface flow reversals, commercial vessel traffic, and temperature and specific conductance in the U.S. Army Corps of Engineers Electric Dispersal Barrier System (EDBS) on the Chicago Sanitary and Ship Canal, Chicago, Illinois. These data are planned to be released on USGS ScienceBase annually. This data release is the summary of all the data collected during water year 2019 (October 1, 2018, to September 30, 2019). Meyers and others (2019) describe all the data collected during October 1, 2018, to September 30, 2019. Water surface flow reversals at the EDBS are monitored using surface velocity radar. Commercial vessel traffic patterns through the EDBS are documented...

The U.S. Geological Survey (USGS) has started monitoring water surface flow reversals, commercial vessel traffic, and temperature and specific conductance in the U.S. Army Corps of Engineers Electric Dispersal Barrier System (EDBS) on the Chicago Sanitary and Ship Canal, Chicago, Illinois. Data are collected during each water year. These data are planned to be released on USGS ScienceBase annually. Data monitored during a water year is released in a separate child item in this page. The metadata in each child item details the data sources and processes used to derive the final data files, and attribute information of each data files.
