Thousand Acre Pasture and the expansive plateaus of Government Flat define the high terrain south of the Columbia River Gorge in this mid-1990s survey. The landscape transitions from the rugged drainage of Lucky Canyon and Ladore Creek in the west toward the agricultural and residential fringes of The Dalles. Water management infrastructure is a prominent theme, evidenced by the The Dalles Watershed Management Unit, Wicks Reservoir, and a series of specialized facilities including a Filtration Plant and Gaging Station.
