The Challenge
Springfield, Illinois relies entirely on Lake Springfield for its water and power supply. Numerous studies revealed that the existing water supply is insufficient during extreme drought conditions, posing a significant risk to the city’s 165,000 residents and critical infrastructure. Climate and streamflow modeling indicated that prolonged drought could lead to severe water shortages, requiring urgent planning for supplemental water sources.
Our Solution
Spheros Environmental (formerly Northwater) supported City Water, Light & Power in developing and permitting an emergency water supply plan. We evaluated two options: constructing a supplemental reservoir and installing a temporary river impoundment. Our team designed and executed a comprehensive monitoring program, developed watershed and reservoir models, and conducted an Antidegradation Assessment to meet stringent water quality standards, including phosphorus limits. These efforts informed strategic management practices to ensure drought resilience.
