Canal W 20 winds through this agricultural landscape in central Washington, anchoring a network of irrigation that defines the local geography. The terrain is marked by distinct depressions, most notably the large feature known as The Pot Hole, which breaks the otherwise orderly grid of the Public Land Survey System. The map reveals a precise infrastructure of rural transit, where named thoroughfares like Dodson Rd N and Kriete Rd intersect with a system of numbered routes including Rd 10.8 NW and Rd 7 NW. This modern survey reflects the enduring influence of 20th-century water management on the development of Grant County, showing how the distribution of water through the Canal W 20 system has shaped land use and boundary lines across Townships 19 and 20 North.
