Effect of the Hastings Hydropower Project at Lock and Dam No. 2 on dissolved Oxygen in the Mississippi River

In 1987, the City of Hastings completed a new hydropower plant on the Mississippi River at Lock and Dam No.2. That facility was constructed in the place of a fixed crest Boule Dam. As part of the Federal Energy Regulatory Commission's licensing procedure, the City of Hastings is required to study and document the impact of their operation on dissolved oxygen (D.O.) downstream of the structure.
