Lock and Dam No. 20

Lock and Dam No. 20 stands as a monumental engineering achievement on the Upper Mississippi River, forming a critical link in the 9-foot navigation channel system. This impressive structure, operated by the U.S. Army Corps of Engineers, functions as a colossal "water elevator," allowing large commercial barges and recreational vessels to traverse the changing elevations of the river. It's not just a functional landmark but also a fascinating point of interest where visitors can witness the intricate dance of river commerce and observe the powerful currents of one of America's greatest waterways.

While lacking traditional curated exhibits, the main attractions here are the dynamic operations of the lock and the vibrant natural ecosystem it fosters. Key sights include the massive lock and dam structures themselves, featuring robust Tainter gates and roller gates that control the mighty Mississippi's flow. The area is a haven for diverse wildlife, particularly providing exceptional birdwatching opportunities. Keep an eye out for majestic Bald Eagles, especially prevalent during the winter months, and a variety of waterfowl that frequent the river. Anglers will find an abundance of fish species such as walleye, sauger, white bass, crappie, and catfish.

Visiting Lock and Dam No. 20 offers a memorable experience that blends industrial grandeur with natural beauty. It's a place to marvel at human ingenuity in taming a powerful river, appreciate the economic artery it represents, and connect with the rich biodiversity of the Mississippi. The rhythmic flow of the river, the passage of towering towboats, and the seasonal migration of birds create a dynamic and ever-changing landscape, ensuring each visit holds a unique charm.
