Inscription. The original dam was built in 1913 and had 28 steel gates. The gates moved up and down to allow different amounts of water to flow under them. The current dam was completed in 1997 and is fitted with five crest gates. These gates maintain levels by allowing different amounts of water to flow over them. Four of the new gates are made of rubber and can be inflated with air. The gate on the west end of the dam is a steel crest gate.

The steel gate on the west side is automatically controlled to keep the upper pool at a prescribed level. It is fully adjustable with many positions from completely open to completely closed.

In summer, water levels are kept near 830 feet above sea level.
