Hennepin Island Hydro Generating Station

Key facts:

  • Power Production Capability: 13.9 megawatts
  • Location: West side of Hennepin Island, Minneapolis
  • Commercial operation: 1882

Overview

Located in the center of Minneapolis, the current plant was built in 1882 on the site of early sawmills to power arc lights. A 1,900-foot-long, 14-foot-high dam, situated on the upper portion of St. Anthony Falls, creates a 450-acre reservoir. The St. Anthony Falls dam was replaced in 2000-2001 with a new dam around 30 feet upriver of the existing structure. The upper island was developed into a park with an access bridge giving public view of main spillway, horseshoe dam and downtown skyline. This plant is also known as St. Anthony Falls Hydro.

Break Ground, Not the Law

Always call 811 before digging in your yard to avoid hitting buried gas or electric lines. Not only is it the safe thing to do, but it's the law.
