Waterfowl production is monitored in the spring, with mallard, cinnamon teal, redhead, scaup, gadwall, ringneck duck and Canada geese the main nesting species. The nesting sandhill crane population averages 50-60 pair.
Yellow rails and Oregon Spotted Frogs which are species of special concern are also surveyed annually. This refuge has a rich cultural heritage, as it includes part of the historic lands used by the Klamath Tribes. Consultation with the Klamath Tribes on refuge management activities is a regular activity.
