Downstream Safety


The production of hydropower at the powerplant is accompanied by a rise in the level of the river below the dam, as water used to drive the generators is discharged into the river. Air horns located on the top of the dam will sound for one minute before water is released into the river. The horns are to alert fishermen and other visitors who might be on the rocks in the riverbed that the river will soon rise and that they must immediately move to the riverbank. For safety’s sake, fishermen are encouraged to fish from the riverbank or from the fishing piers that have been provided.
