The data were georeferenced with a differential GPS receiver with submeter accuracy. These ADCP measurements were collected in support of the US Army Corps of Engineers Great Lakes and Mississippi River Interbasin Study (GLMRIS). Velocity measurements were processed using the Velocity Mapping Toolbox (Parsons and others, 2013) to derive temporally- and spatially-averaged water velocity values. Discharge measurements were processed with the QRev discharge... Categories: Data; Types: Citation; Tags: Brandon Road Lock and Dam, Des Plaines River, Illinois, Joliet, Rockdale, All tags...

We examined a rare long-term record of streamflow and nitrate concentration data (1972–2000) to evaluate annual and seasonal patterns of nitrate losses in streamflow and baseflow from the Raccoon River. Combining hydrograph separation with a load estimation program, we estimated that baseflow contributes approximately two-thirds (17.3 kg/ha) of the mean annual nitrate export (26.1 kg/ha). Baseflow transport was greatest in spring and late fall when baseflow contributed more than 80% of the total export. Herein we propose a ‘baseflow enrichment...

The percent difference was calculated as the absolute value of [(current peak Q - original peak Q)/(original peak Q) x 100], where current peak Q is the 2016 peak and the original peak Q is the 2008 peak. When an original peak Q value is 0, the resultant percent difference calculation is undefined because of division by 0. In these cases, the percent difference field is populated with NA.
