Recent rains in the Lake Springfield area and its watershed have been a welcome occurrence following dry weather across central Illinois that began in late summer 2025. From full pool elevation (560 feet) in early August, the lake gradually declined to over 3.5 feet below full pool in February and early March.
At the current elevation of 558.63 feet (March 24, 2026), which is more than two feet higher than this year’s low, CWLP continues routine operations and there are no water restrictions or conservation requirements in place for customers at this time of year. Lake levels, tributary flow, and seasonal forecasts will continue to be closely monitored should dry conditions persist into spring and summer. Further, if by late spring or anytime from summer to fall, the lake level falls to 556 feet, or four feet or more below full poll, restrictions on some water use could be implemented to ensure an ample water supply is available for our community’s needs until the drought further subsides. Residents are encouraged to practice efficient water use year-round, particularly as the outdoor watering season approaches and when the lake level is low.

Current Conditions & Drought Status
Lake Springfield is fed primarily by Sugar Creek and Lick Creek. During extended dry periods, inflows from both tributaries can slow significantly, limiting the lake’s natural recharge.
By early October 2025, most of Illinois was experiencing at least a moderate drought with some areas more severe. In February and early March, most of Sangamon County was in a severe drought while Morgan, Macon and Christian Counties and eastern Illinois were in an extreme drought. Winter precipitation and recent rainfall events have helped stabilize conditions, and lake levels are now slowly trending upward with a current lake level of 558.63 feet.
In addition to rainfall, CWLP has supplemented the lake by pumping water from the South Fork of the Sangamon River when river conditions allow. Since January 1, approximately 1.5 billion gallons have been pumped into Lake Springfield — raising the lake roughly 1.26 feet. With this assistance, the lake is just below its historical seasonal average of 558.76 feet for the month of March. Additional sustained spring rainfall will be needed to ensure the level increases ahead of outdoor water use season in case drought persists.
Drought Planning & Water Conservation
Lake Springfield has a long history of proactive drought management. In our area’s most recent droughts—in 1988, 2000 and 2012, the Mayor and City Council have enacted various stages of water restrictions in accordance with CWLP’s recommendations when lake levels fall low.
The South Fork pumping station — placed into operation in 1955 — was constructed following a severe three-year drought when the lake dropped more than 12.5 feet and reached a record low in December 1954. The supplemental pumping system remains a critical safeguard for Springfield’s water supply during extended dry periods.
Easy Ways To Save Water
Residents are encouraged to practice efficient water use year-round, particularly as the community approaches outdoor watering season.
• Fix household leaks, ensuring toilets and faucets aren’t wasting water.
• Only run full loads for clothes washing and the dishwasher
• Take shorter showers and use less water for baths
• Use low flow showerheads and faucet aerators
• Limit use water for power washing or spraying off exterior surfaces
• Limit outdoor water use in particular by not using spray irrigation and during daylight hours
Historical Perspective
Lake Springfield has experienced significant fluctuations over its 90-year history:
• Record High: 564.50 feet (April 1994)
• Record Low: 547.44 feet (December 1954)
While current levels have been below seasonal averages, they remain above Lake Springfield’s historic drought lows.
