2023 Map of Conley
USGS Topo · Published 2023About this map
The Grande Ronde Valley floor reveals a complex system of water management and natural drainage near the La Grande/Union County Airport. This 2023 survey illustrates the agricultural character of the region through its reliance on intricate waterways like State Ditch and McAlister Ditch, which redirect flow across the flat terrain. The convergence of the Grande Ronde River and Catherine Creek dictates the landscape's movement, creating a network of sloughs such as Pierce Slough, Wright Slough, and Gekeler Slough. Historically significant landmarks like Conley Lake and the various rural lanes—Peach Rd, Anson Rd, and Gekeler Ln—provide a clear framework for those studying contemporary land use and property boundaries in this part of Union County.
