About this map

The Green River carves a winding path through the high ranching country of western Wyoming, defining the landscape around Forty Rod Flat. During the mid-1960s, this area supported an extensive network of irrigation infrastructure essential for high-altitude agriculture, including the Canyon Ditch, Bickel Ditch, and Horsefly Ditch. These waterways represent the vital engineering of the upper Green River basin, directing water from the main stem and tributaries like Marsh Creek to the surrounding flats.

Evidence of the region's managed water resources is found at Franz Reservoir and the Gaging Sta Warren Bridge, while the Warren Bridge Campground marks a point of recreational access near The Narrows. In the eastern portion of the sheet, the New Fork River flows south, joined by the Pine Grove Ditch. This document serves as a detailed record of the intersections between natural hydrology and the man-made diversions that sustained local land use in Sublette County.
