2020 Map of McKay Reservoir

About this map

Pilot Rock and the surrounding agricultural landscape of Umatilla County are defined by a network of creeks and drainage basins. The McKay Reservoir serves as a central hydrological feature, fed and flanked by numerous named watercourses including McKay Cr, Birch Cr, and Tutulla Cr. The terrain shifts from the low-lying reservoir area to the elevated Stewart Bench and through carved features like George Canyon and Spring Hollow. For local historians and genealogists, the map identifies specific points of local heritage such as Skyview Memorial Park and the McKay Creek Cem. A dense grid of county and local roads, such as Sparks Station Rd and Old Hwy 395, connects these rural homesteads and settlements, illustrating the 21st-century infrastructure of this eastern Oregon farming and ranching region.
