The Twin Valley Dam was officially unveiled June 22 2004. It supplies over 7000 people in southern Alberta with a stable source of drinking water. It also has become a home for many species of birds and other wildlife. Fishing is spotty during the summer but ice fishing seems to be the best time to catch some large Pike. It has a campground as well.The cache is a small size container hidden near parking and the dam with a nice view of the Reservoir and the Mountains.
