Highlights of Dubuque, Iowa
Dubuque, Iowa's oldest city, draws visitors with a lively and historical riverfront district along the mighty Mississippi.
Dubuque's lock-and-dam system
A numbered lock-and-dam system divides the Mississippi River into ever-deeper pools, allowing the Army Corps of Engineers to control water levels. The 16 gates and 600-foot-long chamber of Dubuque's Lock and Dam No. 11 are powerful to behold, filling or emptying the chamber to deliver tiny fishing boats and giant barges alike along the river's "stairsteps." Free tours are offered at 2 p.m. Sundays Memorial Day through Labor Day (563/582-0881; missriver.org). Eagle Point Park, above Lock and Dam No. 11, provides picnic spots and views of the Mississippi (563/589-4263; cityofdubuque.org).
