2017 Map of John Hay Reservoir

About this map

Honeycomb Buttes dominate the northern terrain of this Sweetwater County landscape, where deeply etched contours reveal a complex drainage system flowing toward the high desert basins. Water management defines the southern half of the quadrangle, anchored by the John Hay Reservoir and Brannan Reservoir. These catchments collect seasonal runoff from several local tributaries, including Bear Cr, N Fork Bear Cr, and Red Cr. The map illustrates the grid of the Public Land Survey System, specifically marking the convergence of townships T25N and T26N with ranges R98W and R99W. This corner of Wyoming reflects a quintessential western ranching and water-retention landscape, where infrastructure is sparsely distributed and dictated entirely by the availability of water in an arid environment.
