OWMA lies in the lower extremes of the Moapa and Virgin river valleys where they flow into the north end of the Overton Arm of Lake Mead. This is about 65 miles northeast of Las Vegas using Interstate 15 and State Route 169. Located in the Mojave Desert, OWMA supports an abundance of fish and wildlife that contributes significantly to the biological diversity of southern Nevada. Desert riparian habitat, associated with the floodplain of the Muddy and Virgin rivers, is extremely important to wildlife populations. The dense shrubbery of desert wash habitat provides food and shelter for small mammals and many species of birds. Numerous wet meadows and ponds dot the landscape, providing food, cover, and water for birds, mammals, reptiles, and amphibians. The deep water of Lake Mead provides habitat for fish, cormorants, and diving ducks, while shallow littoral zones provide feeding areas for puddle ducks and shorebirds. 1. During the waterfowl season, hunting is permitted on the Moapa Valley portion of the area only on the opening day of the duck season, even numbered days thereafter throughout the season, opening day of the goose season, and the closing two days of the duck and goose seasons. Before or after the waterfowl season, hunting is allowed every day for wildlife species upon which there is an established open season. 2. During the opening day and the first weekend of the dove season the maximum capacity for the Moapa Valley portion of the area is 60 hunters by reservation only. 3. During the waterfowl season on the Moapa Valley portion of the area, hunters must hunt from assigned hunt locations (blinds) constructed by the Department of Wildlife. A maximum of up to four hunters are permitted at each hunt location. Assigned hunt locations are marked by numbered stakes. Hunters shall hunt only within their assigned hunt location and moving to vacant locations is prohibited. The only exception involves reasonable accommodation of the disabled. 4. The hunting of upland game species is prohibited during the waterfowl season. 5. On Overton Hunt days, only persons authorized to hunt waterfowl may use vessels on the portion of the area inundated by Lake Mead. Trapping is allowed with valid permit. Permits will be issued through a drawing process and may contain designation of specific trapping areas, dates or other restrictions to ensure compatibility with other public activities. The discharging of a rifle or pistol is prohibited. The use or possession of shells for a shotgun containing shot that is toxic or larger than standard-sized T is prohibited. The use of shotguns capable of holding more than three shells is prohibited unless it is plugged with a one piece filler, incapable of removal without disassembling the gun so its total capacity does not exceed three shells.
