About this map

Mark Twain Lake dominates the center of this landscape, its complex, branching shoreline formed by the impoundment of the Salt River. The Clarence Cannon Dam stands as the primary engineering feature on the eastern edge of the reservoir, a massive structure that transformed the river valley into a major regional water resource. The map reveals the intricate network of flooded drainages, including Madden Br and Rocklick Br, which now form the deep coves of the lake.

Evidence of the area's pre-reservoir history remains in the placement of small communities and local landmarks. The settlement of Joanna sits near the water's edge, while Shaver Ford and The Landing mark key access points and historical crossings. Genealogists may find interest in the Utterback Cem, which persists on the southern hills near Cedar Ridge. The terrain is further defined by smaller bodies of water like Henderson Lake and Monroe Lake B, scattered across the undulating border of Monroe and Ralls counties.
