Huntsville DamHuntsville, Rd., Dallas, PAHuntsville Dam is a natural made lake that hasn't change a lot over the years because it is a community water source and unused by man. There are only 3 houses built on its banks and they have only been there for about ten years and are only visible from certain angles. You are not even able to drive or walk around the entire lake because much of it is surrounded by woods that are off limits. It is a true natural beauty.
