2010 Map of Keystone Dam

About this map

The Keystone Dam anchors this 2010 landscape where the Arkansas River and Cimarron River converge, creating a complex shoreline of inlets and peninsulas. The settlement of Mannford sits at the southwestern edge, adjacent to the Mannford Water Supply Lake, while numerous small communities and residential developments like Westport, Prue, and Sha-To-She are scattered across the fingers of land reaching into the water. This era of the landscape is defined by its recreation-centric development, evidenced by the Keystone Air Park and many named ridges and groves such as Dawson Ridge and Shady Grove. Genealogists will find several burial grounds preserved amidst the suburban growth, including Dixie Cemetery, Prairie View Cemetery, and the East Basin Cemetery, providing points of continuity for families with deep roots in this river valley region.
