Developments since 1989:
The Evergreen Lake spillway was raised 5 feet in 1995. The Mackinaw River was used in 2000 and 2006. New groundwater sources are being evaluated, including a ~20 mgd regional supply in western McLean County and another in the Danvers bedrock valley of the Mahomet aquifer that could provide 2-3 mgd for blending when nitrate levels in Lake Bloomington are high.
