Description |
English: River Dam #27 on the Mississippi River, North Riverfront Park Lake, Missouri. View of the 2925 foot low-water River Dam 27, the first permanent rock-fill dam across a major river in the United States. This dam was built in 1960 to ensure adequate depths over the lower sill of the old Alton Locks that was 12.5 river miles upstream.
