About this map

Moses Lake serves as the central focal point of this Grant County landscape, showing the complex interaction of water and settlement as of 2023. Residential expansion is evident in communities like Mae Valley, Cascade Valley, and Westlake, which wrap around the distinctive water arms of Lewis Horn, Parker Horn, and Pelican Horn. The map documents a highly developed shoreline where suburban street grids, such as those near W Broadway Ave and S Division St, meet the irregular edges of the lake.

South of the primary settlements, the terrain transitions into a more hydrologically complex environment dominated by the northern reaches of the Potholes Reservoir. This area is characterized by a series of landforms including Goat Island, Gaileys Island, and Marsh Island. The intricate network of Sand Dunes Rd and various frontage roads illustrates the modern transportation infrastructure supporting both the residential centers and the recreational access to the surrounding reservoir and islands.
