The majestic Bigelow Mountain Range looks down from Flagstaff Lake's southern shore, making the Dead River region a scenic favorite for outdoor enthusiasts. It is a popular river with whitewater boaters and rafters. The whitewater releases are controlled from Flagstaff Lake, which has been dammed and made into a
