1350 Dam Rd
Hastings, MN 55033

Lock and Dam #2, located along the Mississippi River at mile 815.2 near Hastings, Minnesota, has been a critical infrastructure since its construction in 1930. Due to settling and tilting of the original lock walls, a second lock was built and completed in 1948, ensuring smooth navigation along the river.

The dam at Lock and Dam #2 boasts a substantial concrete structure spanning 722 feet and equipped with 19 Tainter gates, each 30 feet long. Additionally, the dam features a 4.4-megawatt power plant owned and operated by the city of Hastings, providing an interesting blend of historical significance and modern functionality.

Visitors can explore the Earth embankment stretching 3,000 feet and witness the lock, offering a passage 110 feet wide and 600 feet long for vessels to traverse the river. The site underwent extensive rehabilitation between 1987 and 1995, ensuring its continued operation and contribution to waterway management.
