Why it's listed

Dresden Island Lock and Dam is a navigation complex on the Illinois River near Morris, built between 1929 and 1933 and opened in 1933. The district contains a lock with a 22-foot lift and a 110 by 600 foot chamber, an unfinished auxiliary lock, a 1,505.5-foot concrete and earth dam, and a red brick control station with gabled bays reminiscent of the Jacobethan style. Walter Mickle Smith, Chief Design Engineer for the Illinois Waterway project, is considered the designer. The facility was part of a slackwater system that allowed commercial barges and towboats to travel the waterway between Chicago and the Mississippi River, and it helps maintain water levels at Lockport and Joliet. It was recognized for its role in transportation and maritime history and as a representative example of Army Corps of Engineers lock and dam design. Gates, machinery and surfaces have been replaced over the years, but the site keeps its original appearance and function. Three small modern buildings are noncontributing.

What listing means for this property

This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
