The Columbia River and Snake River confluence anchors this regional overview, illustrating the mid-century development of the Tri-Cities and the expansive Hanford Reservation. This era reflects a landscape of intensive land management, from the military operations at Larson AFB and the Survival Training Area to the protected wetlands of the Columbia National Wildlife Refuge. The irrigation and hydroelectric potential of the basin is evident in the network of reservoirs like Potholes Reservoir and Lake Sacajawea, which reshaped the ancient drainage patterns of Crab Creek and Esquatzel Coulee.
