The first refuge acquisitions specifically for management of waterfowl came about with the Acts establishing the Upper Mississippi River Wild Life and Fish Refuge in 1924 (again through impetus provided by the Izaak Walton League) and the Bear River Migratory Bird Refuge in 1928. Prior to this, the initial attempts to provide for the systematic acquisition of new lands for refuges had begun in 1921. A bill was introduced in Congress that would establish a "Refuge System," a Migratory Bird Refuge Commission, and a one-dollar Federal hunting stamp.
