NOTICE: In January , USGS WaterWatch began operating in maintenance-only mode. Existing tools, features, and web data services are being fully maintained as before, but new tools and enhancements will no longer be developed. Please contact USGS WaterWatch if . Appendix C. River Basins for which the Illinois Streamflow Assessment Model Has Been Developed 46 LIST OF FIGURES Figure 1. Some sample annual flow-duration curves 2 Figure 2. Estimation of the 7-day and day low flows from the daily flow records 3 Figure 3. Transformation of the annual flow-duration curve to other parameters 5 Figure 4. Low flows in Illinois streams occur most often in the fall months and do not occur in March or April, which are months of high spring flows, snowmelt, and high water table. Therefore, the water year selected for low flow analysis was taken to begin April 1 and end March 31 of the following year. The United States Geological Survey publishes updated drought maps on their website. There you can view a map that shows where below normal 7-day average stream flow conditions were recently recorded. The maps are updated daily. Get a current Illinois drought map here.
Statewide Water-Quality Real-Time Table Real-time data typically are recorded at minute intervals, stored onsite, and then transmitted to USGS offices every 1 to 4 hours, depending on the data relay technique used.

The flood peaked that day at PM Eastern Time in the evening, when the stream stage reached feet with a corresponding instantaneous streamflow of 6, cubic feet per second (cfs). Alternatively, base flow at Peachtree Creek (left picture) is around feet, with a streamflow of about 25 cfs. (Credit: Howard Perlman, USGS).
