About the Water and Atmospheric Resources Monitoring Program
The Water and Atmospheric Resources Monitoring (WARM) Program and its networks conduct long-term monitoring across Illinois, measuring the state’s waters, soils, and climate.
- Illinois Climate Network (ICN) -- weather and soil data
- Shallow Groundwater Network – water table levels
- Benchmark Sediment Monitoring Program – suspended sediment concentrations and particle sizes
- Reservoir Network – monthly lake levels
Provisional and statistical monthly streamflow data from selected USGS stream gages are also on the WARM website.
Data from WARM and other monitoring programs are reported monthly in the Illinois Water and Climate Summary. The Summary provides information on the current and trending conditions of the state’s water and weather and their impacts on other resources.
