Two river navigation trade associations say the Army Corps of Engineers will blow up rock outcrops on the Mississippi River next week. The rock pinnacles in Thebes, Ill., could block river traffic after Christmas if water levels continue to fall. The rock removal is a half-victory for barge companies, who also want the Corps to release water from Missouri River reservoirs.
American Waterways Operators spokesperson Ann McColloch says the rock blasting project is welcome news, but adds the work will take an extended period of time.
