Lake Wallula dominates the landscape at the meeting of the Snake River and the Columbia River, reflecting a mid-century period of massive hydroelectric and navigational transformation. The reservoir created by the McNary Dam stretches across the quadrangle, drowning former riverbanks and creating the intricate network of the Mc Nary National Wildlife Refuge. Within this riparian environment, numerous islands and ponds like Peavine Island, Tanglefoot Island, and Curlew Pond emerge from the backwaters, while Ice Harbor Dam regulates the eastern flow of the Snake into Lake Sacajawea.
