Scarce regional map of the region extending from Yuma and the Colorado River to Oatman Flat, which at the time was the site of a proposed reservoir.
The map was prepared by the Citizens Executive Committee on a proposed reservoir and irrigation of Yuma County, in August, 1889. Terrific detail along the Gila River including surveyed townships and topography. Lines show the limits of irrigated lands at different water levels in the proposed reservoir.
A rare and fascinating piece of Arizona history.
