The dam is there to prevent the river from flooding. Due to the incessant rain for the last months, the lake's water level had gone higher than normal. They had to open up the spillway gates to allow lakewater to flow through the river. They did for a while. It had resulted to a little bit of flooding in some lower areas where the river passes through. To make the long story short, Jeff had to come in for a brief overtime so he could lower down some of the gates. He brought us along, gave us a tour and showed me the dam's walkway which was cool because it's just under the bridge. It was a bit scary but perfectly safe. We didn't go to the loud part of the plant which houses the huge turbines, generators and stuff. It was quite an interesting experience.
The lowest part of the dam which is completely submerged in lakewater. It's the coolest part of the plant as well. It still feels like winter here.
