Summersville Lake is good for all kinds of activities. It is frequently used for training and check out dives. There is a 25 foot platform and I believe there may be one around 80 feet (or actually it may be the winter boat ramp that they use for AOW). Visibility is pretty good depending on how many people are in the water. There are 3 sunken boats throughout the lake and some huge boulders. Fish are sunnies and bass and crayfish. Definitely an enjoyable time.
