2015 Map of Poison Lake

About this map

The historical Emigrant Trl cuts across the northeastern corner of this Converse County landscape, marking a legacy of westward expansion through the high plains. Water management defines much of the human footprint here, visible through irrigation and stock control features like Darlington Reservoir Number 1, Trail Reservoir Number 1, and Saddleback Reservoir. These man-made catchments sit alongside natural features such as the eponymous Poison Lake and the prominent Manning Ridge. The drainage system is dominated by the forks of La Bonte Cr, including W-Fork-La-Bonte Cr, which carve through the terrain alongside Trail Cr and Mill Cr. Modern access is provided by rural routes like Esterbrook Rd and Braae Rd, connecting the scattered ranching interests that have historically utilized these drainages for livestock in the open range of eastern Wyoming.
