7-Day 10-Year Low Flow Maps

Map 4. Spoon River Region


The low flow estimates presented here for the Spoon River region are as published in a 1988 report by the Illinois State Water Survey (Singh et al., 1988a), and an analysis of streamflow conditions based on data collected prior to and including the 1984 water year. The low flows on some streams in the Spoon River region may have changed somewhat since 1984 as a result of changes in water use and natural climatic variability. However, it is expected that the low flows for most streams in this region, if estimated using present-day data, would remain similar to the values published on this map. There are no immediate plans to update the Q7,10 values for the Spoon River region.
