No, the lake was created as a cooling pool for a coal powered electric plant, which by the way is directly across from the SCUBA area. It is pretty neat. Anyways, the water from the lake is circulated thru the lake to cool the turbines and when the water is pumped back into the lake the temp is around 110 degrees. That is why the water is so warm in the summer. In fact it is known for getting over 100 degrees. The big draw about Mt Storm is that is stays warm during the winter. Well, it used to anyways. It would stay in the 60's throughout the winter. However, the past two winter I believe, not all the generators in the plant were running, so the water did not heat up. In fact when I was there this past Februrary, the water was 38 degrees. If you go on a weekend, plan on 30-50 other divers being there as well. A week day is usually pretty empty.
