| Figure 8. -- Fenced Stock-water pond in eastern Montana. This is a new fence, and therefore there is little difference in vegetation inside and outside the fenced area. Stock cannot enter the enclosure, and rapid plant growth will occur. Planting to provide food and cover for waterfowl is the next step in development. Throughout eastern Montana, the State is improving these ponds, which were designed by the U.S. Soil Conservation Service. |

| Figure 9c. -- Waterfowl-habitat improvement under New York's extensive program of marsh development. Flowed areas as seen from spillway. Three weeks after flooding, 57 waterfowl were observed on this 9-acre marsh. Through 1955, more than 600 such areas have been created in New York State. They average 4 to 5 acres and support about 2 pair of breeding ducks per marsh. |

| Figure 10. -- Willow Slough State Game Preserve in Newton County, Ind., created in 1952 by a 1,200-foot dam that impounds 1,500 acres of shallow water over land formerly drained for agriculture. Peak populations of more than 1/4 million ducks and 2,500 geese have been observed. One half of the area is left open for public watefowl hunting. The lake also furnishes excellent opportunities for public fishing and trapping. |
