(KSDK) - Authorities are searching Carlyle Lake in Clinton County, IL for two men who went missing while boating Saturday night.
Three men were boating near Boulder Marina on the east side of the lake when one of the men jumped in the water. While he was swimming wind blew the boat away from him. The man was struggling to swim back to the boat. One of the other boaters got in the water to assist the man. Soon after, both men went under and did not resurface.
The third man did not know how to operate the boat and was unable to help the men in the water.
The search for the men began around 1 a.m.
The Army Corps of Engineers and the Illinois Department of Natural Resources Conservation Police are leading the search.
An official with the Conservation Police says the search is now considered a recovery effort.
