About this map

The La Grande Reservoir and its associated La Grande Dam anchor this upland landscape in Union County, where complex water management systems navigate the high terrain. The map details the vital La Grande Aqueduct as it contours through the mountains, a significant piece of local infrastructure serving the region's needs. This 2011 survey documents a topography defined by prominent summits such as Elk Mountain and the long spine of Beaver Ridge.

Stream networks are dense and intricate, featuring Whiskey Creek and its various forks alongside the winding path of Jordan Creek. Numerous Forest Service routes, including Whiskey Creek Rd and Ladd Canyon Rd, provide the primary access to these slopes. The map also identifies specific natural water sources like Beaver Spring, illustrating the importance of hydrology in this high-elevation environment.
