Lake Ilo NWR is managed primarily to provide waterfowl with the best nesting and brood-rearing conditions. Resident wildlife species also thrive under these same management techniques. Prescribed burning, livestock grazing, and mowing all help in removing dead plant matter from the uplands and allowing native plants to grow in taller, thicker stands.
Water levels at Lake Ilo are regulated to maximize opportunities for both migrating and nesting birds. Flooding and drawdowns of the lake are timed to stimulate plant growth, provide exposed mudflats for shorebirds, and to aid in maintaining the fishery that is established in the lake. By adjusting these water levels, different habitats can be provided not only for birds and fish, but for mammals, reptiles, amphibians, and insects, such as butterflies, as well.
