Creating optimal conditions for aquatic vegetation through flexibility in dam operations
The Upper Mississippi River in Illinois and Missouri supports a major navigation route as well as many other needs. In the late 1980s and early 1990s, aquatic vegetation nearly collapsed. Unique hydrologic conditions required low end river operations in 2014 and an additional benefit was the reappearance of perennial aquatic plants.
A collaborative effort is allowing for lower water levels when conditions permit to determine longer term effects on these plants and river operations.
