Grays Lake National Wildlife Refuge is not a lake. It is the largest hardstem bulrush marsh in North America. The refuge is known for its large nesting population of sandhill cranes, Franklin’s gulls, and trumpeter swans. In the fall, local waterfowl gather in open water and provide hunting opportunities until the marsh freezes. Although non-motorized boats are permitted, a boat is not necessary for waterfowl hunting on the refuge. There are no launching ramps, and the marsh is suitable for car-top type boats only. Hunting is heavily dependent on the weather, and an early freeze can move most of the birds south.
Hunting for ducks, geese, coots, and mergansers is permitted in designated areas, and in accordance with all state and federal regulations. Approved non-toxic shot is required. Hunters should consult the Idaho state hunting regulations. Special refuge regulations may also apply, contact the manager for more information at 208-574-2755.
