The only dam in the St. Paul District with a hydroelectric facility
The site underwent major rehabilitation from 1987 to 1995, at which time a hydroelectric plant was added.
The dam consists of a concrete structure 722 feet long with 19 tainter gates that are 30 feet long. The power plant is a 4.4-megawatt hydroelectric plant that is owned and operated by the city of Hastings. It is the only facility of its type at a lock and dam in the St. Paul district.
There is also an earthen embankment 3,000 feet long.
The site has a public observation deck that overlooks the lock for watching locking operations. The deck and restrooms open from dawn until dusk each day from mid-April through late-October.
