Locks & Dams

A number of dams on the Ohio and Kanawha rivers manage water resource by insuring sufficient water levels for ships and barges traveling on the river. Each dam has a set of associated locks to allow the passage of river traffic. To control water flow, the gates in the dam are raised and lowered by electric hoist motors. C&M designed, built and installed a computer network at each dam, allowing control and monitoring of each of the gates either from a local operating station or from the district office located miles away. A Programmable Logic Controller at each gate controls and monitors gate position. Control and status information pass through fiber optic cable to central desktop computers at multiple operator consoles.
