HELPING SOLVE A DECADES-OLD PROBLEM
Since 1966, the base flow of the Root River has been too low to support water quality, recreation, and fishery goals in the watershed. But remedies explored over the years by the DNR and Southeastern Wisconsin Regional Planning Commission have all proved too costly.
By using the river to return clean, treated water to Lake Michigan, the Great Water Alliance effectively solves the problem of low base flow in the dry summer and fall months. And, while the 8 million or so gallons a day that enter the system will help raise levels by as much as 6.5 inches during low-flow conditions, studies confirm that this same amount will be virtually undetectable during high-flow events.
