Parking on the highway shoulder gives one a good view of any waterfowl and gulls loafing on Roberts Creek Lake.

On the north shore of Lake Red Rock in northern Marion Co. Gulls are viewed by looking north from the causeway along G-28, about three miles east of Hwy. 14. Open water.

The entire area is important as a resting area for large concentrations of migrating waterfowl, gulls, and shorebirds. The area is also critical as a wintering area for large numbers of Bald Eagles. Nesting birds include Bobolink, Cerulean Warbler, Black-billed Cuckoo, Wood Thrush, and in some years Kentucky Warbler.

The Red Rock Dam is about five miles southwest of Pella; the refuge area extends northwest beyond Runnells in Polk County to near Hartford in Warren County.
