2020 Map of Jameson Lake SW

About this map

Moses Coulee dominates this Douglas County landscape, revealing the dramatic geological forms of the Columbia Plateau. This 2020 USGS survey records a sparsely populated region characterized by deep canyon walls and dry drainage systems, where local water sources like Sulphur Spring and Coyote Spring historically anchored life in an arid environment. The map details the winding course of McCartney Cr as it flows through the floor of the coulee, paralleled by a network of rural routes such as S Jameson Lake Rd. While the northern reaches are defined by larger sections and section lines like E Baseline Rd, the southwestern corner shows more recent residential development near the junction of Coulee Meadows Rd, including suburban-style naming conventions like White Oaks Dr and Ashwood Pl.
