About this map

Moses Lake serves as the central focal point of this Grant County landscape, where the irregular shoreline creates distinctive peninsulas and inlets such as Pelican Horn and Parker Horn. The residential development of Westlake and Cascade Valley hugs the water's edge, reflecting the mid-20th-century growth of these communities along the lake’s eastern and western reaches. To the south, the terrain transitions into the complex wetlands and hydrology of the Potholes Reservoir, a significant feature for regional water management and habitat.

Several prominent landforms rise from the water, including Galleys Island, Goat Island, and Marsh Island. The transportation network is defined by major corridors like Westlake Rd and Mae Valley Rd Ne, which connect the outlying areas of Mae Valley to the urban center. The southern portion of the map is particularly notable for its absence of dense settlement, dominated instead by the shifting landscape along Sand Dunes Rd.
