There will be daily chances for scattered thunderstorms across portions of the Central and Eastern U.S. through the weekend, with severe thunderstorms possible in the northern Plains and Upper Midwest. Potential severe storm hazards may include large hail, damaging winds, and a few tornadoes. Storms could also produce heavy rain that may lead to isolated instances of flash flooding. Read More >
Effective January 31, 2023, the datum, or gauge zero, will change for the DuPage River at Shorewood, Illinois. This will require changes to the past crests, documented flood impacts, and flood impact categories. These changes are necessary to prevent negative stage values on the gauge during periods of extended dry weather.

DuPage River at Shorewood
Datum (Gauge Zero) Action Stage Minor Flood Stage Moderate Flood Stage Change from 7.5 to 17.5 feet Major Flood Stage
River forecasts for this location will still be issued when the water level has reached, or is expected to reach, action stage. These changes are related to the removal of Hammel Woods Dam in late 2021. Dam removal changed the behavior of the river at the gauge location such that the river is now at lower stages when passing the same amount of water. An analysis by the US Geological Survey has indicated that stage values may go below 0 feet (negative) during periods of extended dry weather. To avoid such a situation, the datum is being changed to make stages report at higher values for the same amount of flow. |
