St. Anthony Falls Locks & Dams, Mississippi River, Minneapolis, Minnesota. Reconnaissance Report for Hydropower

摘要

This report presents a preliminary evaluation of the additional hydropower potential at both Upper and Lower St. Anthony Falls. Two existing hydropower plants owned and operated by Northern States Power Company generate at nameplate capacities of 12.4 Mw (megawatt) and 8.0 MW at Hennepin Island (Upper St. Anthony Falls) and Lower DAm (Lower St. Anthony Falls), respectively. The study shows that incremental added capacity of up to 15.0 Mw at Hennepin Island and 8.4 Mw at Lower Dam is economical. pertinent data concerning the sites are given. Severe environmental impacts do not appear to be associated with construction of plants of the sizes investigated. The District Engineer recommends that the Corps of Engineers prepare a feasibility report which can serve as a basis for congressional authorization for hydropower plant(s) construction at St. Anthony Falls.
