About this map

Soap Lake anchors the southeastern corner of this Grant County landscape, showing the town's grid and recreational areas like Lakeview Park as they appeared in 2011. The terrain is defined by the steep coulee walls and the string of water bodies that include Lenore Lake, Little Soap Lake, and the seasonally variable Dry Lake. This geography reflects the region's glacial legacy, where massive floods carved deep basalt canyons such as Sparks Canyon and Sheep Canyon.

Modern water management is evident through the Main Canal and its associated Canal Maintenance Rd, which contrast with natural water sources like Pate Spring. The local infrastructure is mapped in detail, showing the network of rural routes such as Whitehall Rd SE and Piklee Rd that traverse the high ground above the lakes. This survey provides a precise look at the intersection of natural volcanic geology and the irrigation systems that sustain the modern Columbia Basin.
