Wallula Habitat Management Unit Professional Review and Guide
"This is a lonely area of the Walla Walla River Delta, where the Walla Walla River empties into the Columbia River. The waters here are flat and slow moving, creating great habitat for a number of birds and animals, both in and out of the water.
However, beyond the rich riparian world at the rivers’ edges, the desert rolls on. So fish and frogs, waterfowl and beavers live as neighbors with desert-dwelling rattlesnakes, horned lizards, scorpions, and kangaroo rats. All in all, this is a novel world to explore."
