Unit 650

The Fort Peck Reservoir forms the unit's western anchor, its eastern shoreline providing a reference line for navigation. Big Butte and Willis Buttes serve as prominent glassing points and visual markers across the rolling terrain. The Milk River Hills and divides like Romine and Bonin provide modest elevation for scanning country.

Hell Gate Reservoir, Jays Reservoir, and smaller impoundments dot the landscape, offering not just water but also navigation waypoints in open country. Streams like Skull Creek, Prairie Elk Creek, and Remuda Creek trace major drainages that funnel wildlife movement and provide hunting corridors.

The entire unit sits in the lower elevation band, ranging from roughly 1,800 feet near the Missouri River to just under 2,900 feet on the higher buttes and divides. This is fundamentally prairie and grassland country with minimal forest cover. Low sagebrush and shortgrass prairie dominate the open flats, while scattered juniper and cottonwoods cluster in drainages and around water sources.

The buttes—Big Butte, Willis Buttes, Lone Butte, and others—break up the monotony with rocky outcrops and scattered trees on their slopes. Habitat here favors open-country species adapted to semi-arid plains conditions.

The unit has extensive road infrastructure—over 2,800 miles of roads—but public land is limited, creating a complex access puzzle. Many roads cross private property, so confirmed public access points are critical before heading into the country. State Route 200 borders the south and provides a main access corridor.

The abundance of roads paradoxically doesn't guarantee easy hunting access; much terrain is roadside-visible but posted. Hunting pressure concentrates around known public access points and reservoir areas. The flat to rolling terrain means glassing from roads is productive, reducing need to hike far from vehicle access.

Unit 650 occupies the lower Missouri River valley and surrounding plains in northeastern Montana, encompassing portions of McCone, Garfield, Dawson, and Richland Counties. The unit stretches from Fort Peck Powerhouse on the Missouri River eastward to the North Dakota border, then south to State Route 200 near Fairview, encompassing the Fort Peck Reservoir's eastern shoreline. This is a sprawling, relatively flat landscape at the northern edge of Montana's prairie country.

The terrain transitions between open grasslands, scattered buttes, and low ridge systems that provide modest relief from the plains.

Water is the limiting factor in this unit. The Missouri River defines the western boundary, while Fort Peck Reservoir provides a large water body, but public access to it is mixed. Scattered reservoirs—Hell Gate, Jays, Fatzinger, and others—offer intermittent water sources, though reliability varies seasonally.

Springs including Alecs Springs, Alexander Springs, Norris Springs, and Bonin Springs are scattered throughout but require local knowledge to locate. Creeks like Skull Creek, Prairie Elk Creek, and Remuda Creek flow seasonally, making water planning essential. In this semi-arid country, animals concentrate near reliable water sources during dry periods.

Elk, mule deer, white-tailed deer, and mountain lion inhabit this unit's prairie and grassland habitat. Early season mule deer and white-tailed deer hunting works the brushy drainages and butte slopes where cover concentrates. Elk in this country are spread across open plains and scattered timber; they migrate with water and grass conditions.

The low, open terrain favors glassing and spotting-and-stalking tactics over dense-cover hunting. Mountain lions hunt the same terrain; sign appears along creeks and around reservoirs. Spring bear season isn't applicable.

Success depends on understanding private-public boundary lines, locating reliable water sources, and reading animal movement along the scattered ridges and drainages that offer relief in otherwise open country.
