2023 Map of Tapper Lake

About this map

The Picabo Hills define the northern horizon of this high-desert landscape along the border of Blaine and Lincoln counties. Water management is the primary narrative of this terrain, where natural features like Sagebrush Spring and the Jim Byrns Slough exist alongside an extensive network of human-made irrigation infrastructure. The lower half of the quadrangle is defined by the Richfield Canal, East Main Canal, and West Main Canal, which feed a series of numbered laterals including Lateral 731 and Lateral 917. Scattered across the interior are essential catchments such as Tapper Lake, Sonners Reservoir, and the curiously named Unique Reservoir. This web of canals and reservoirs underscores the transition of the Snake River Plain into productive agricultural land, connected by a grid of rural routes like Forks Division Rd and Cottonwoods Rd.
