Abstract

Forney's Lake in Fremont County is a popular waterfowl concentration area along the Missouri River with a history of lead poisoning of mallards. About 1,500 mallards died from lead poisoning in 1960 and about 2,500 in the winter of 1965 and 1966. A total of 143 bottom samples taken in 1966 and 1967 indicated an average of 1.6 pellets per square foot were available to waterfowl. Lead poisoning losses on this area can be minimized by regulating water levels after the hunting season to move the birds elsewhere.
