The Corps of Engineers Office at Lake Red Rock is holding a couple of open house in December that will give the public the chance to learn about the next 25 years of the lake. The open houses will have information on both the recreation plans for the lake, and on environmental stewardship goals. The open houses will be held in both Knoxville and Pella. In Knoxville it will be at the Sprint Car Hall of Fame and Museum on December 11th. In Pella it will be on December 12th at Central College.
