Due to work delays, the U.S. Army Corps of Engineers, Rock Island District, announces the full road closure of Highway T15 across Red Rock Dam will now begin April 17 instead of April 5 as previously announced. The closure, which is necessary for preventive maintenance to the Red Rock Dam, is expected to last through June 12 and a detour will be in place.

Additional partial road closures may be needed through 2024 for rehabilitation projects on the dam. For more information, please contact the US Army Corps of Engineers at Lake Red Rock at 641-828-7522 or via email at
