| Definition Of: |
Roller Dam
A dam constructed of a series of concrete piers across the river with a series of steel cylindrical drums between each pier. These drums are rolled up and down an inclined gear track in the piers, thus controlling the flow of water through the dam. Water passes under the rollers rather than over the top as in a fixed or wicket dam. (TNDOT1)
