The dataset is comprised of river conditions at La Grange, Peoria, Starved Rock, Marseilles, and Dresden Island Locks and Dams, along the Illinois River. Data were recorded bihourly from 1 Jan 1985 – 31 Dec 2016. For each location, pool elevation (ft), tailwater elevation (ft), head height (ft; calculated by the difference between pool elevation and tailwater elevation), discharge (cfs; when available) and total gate openness (sum of all open gates in ft), are given, where available. Open river conditions were calculated (0 = closed, 1 = open) for each two hour time period. Dam openness was assessed using the U.S. Army Corps of Engineers thresholds for open river conditions at each location.
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
