Unit 16B

Yuma

Colorado River canyon country where low desert meets perennial water and rugged shoreline terrain.

Hunter's Brief

Unit 16B is a compact lower-elevation area centered on Lake Havasu and the Colorado River corridor, bounded by I-40 to the north and state lines to the south and west. The terrain is predominantly open desert with scattered rock formations and minimal timber. Good road access via highways and well-developed infrastructure supports hunting pressure, but the abundant water and canyon habitat support a diverse species mix. Hunting is straightforward in the accessible flatlands, though canyon access requires caution near the reservoir.

Terrain Deep Dive

Landmarks & Navigation

Lake Havasu itself serves as the unit's most obvious reference point, with multiple bays and coves marking the shoreline: Thompson Bay, Havasu Cove, and Steamboat Cove provide water access and navigation landmarks. Rock pillars and formations dominate the visual landscape—Castle Rock, Steamboat Rock, and The Needles offer glassing vantage points and orientation markers. Powell Peak and Cathedral Rock anchor the skyline for navigation.

The Colorado River corridor and Bill Williams River drainage form natural travel routes, while Standard Wash, Palo Verde Wash, and Indian Peak Wash provide secondary drainages for exploring the interior. Picture Rock Window arch offers a distinctive reference point.

Elevation & Habitat

Elevations span from 413 feet along the Colorado River to just over 2,250 feet on the surrounding plateau, creating a low-desert environment with minimal forest cover. The landscape is predominantly open country—sagebrush flats, creosote scrub, and sandy basins—interrupted by scattered rock outcroppings, mesas, and canyon walls. Riparian corridors along the river and Bill Williams provide critical vegetation density and shade.

The sparse canopy reflects the Sonoran Desert climate, though pockets of vegetation occur where water seeps from canyon walls or concentrates in arroyos. This is genuine low-desert hunting terrain.

Access & Pressure

Well over 400 miles of maintained roads crisscross the unit, including direct connections to I-40 and U.S. Highway 95, indicating excellent accessibility and likely moderate hunting pressure. The flat terrain and connected road system mean most of the unit is reachable by vehicle, reducing bushwhacking. Desert Hills and Jops Landing serve as small population nodes.

The straightforward topography and road access make this unit easy to hunt but likely concentrate pressure in accessible areas near the lake and river corridors. Hunters seeking solitude will find more opportunity in the interior washes and mesa tops away from developed areas.

Boundaries & Context

Unit 16B occupies the Colorado River valley on Arizona's western border, framed by Interstate 40 to the north, the Arizona-California state line to the west, the Bill Williams River confluence to the south, and U.S. Highway 95 to the east. The unit forms a moderate-sized rectangle straddling one of Arizona's major river corridors. Lake Havasu—an impoundment of the Colorado River—dominates the landscape and serves as the unit's primary geographic anchor.

The terrain is accessible via major highways on three sides, making it well-connected to regional hunting infrastructure.

Water & Drainages

Water availability is exceptional for this region due to the Colorado River and Lake Havasu, providing reliable surface water throughout the unit. Multiple desert washes—Standard Wash, Palo Verde Wash, Neptune Wash, and others—carry seasonal runoff and may hold water in deeper pools. Jackpot Spring offers a named water source in the interior.

The Bill Williams River confluence adds another permanent water source. This abundance of water in lower-elevation desert is the unit's defining feature and supports year-round hunting. Water management and access points become tactical considerations given the developed shoreline and reservoir infrastructure.

Hunting Strategy

Unit 16B supports a diverse species array across low-desert habitat. Mule deer and white-tailed deer utilize riparian areas and canyon bottoms where vegetation concentrates; early morning and evening glassing of washes can be productive. Pronghorn prefer open flats and sagebrush basins—spot and stalk works on this terrain.

Desert bighorn sheep frequent canyon walls and rock outcroppings; glassing from elevated points around Cathedral Rock and Powell Peak offers opportunities. Javelina are common in brushy drainages. Mountain lions hunt throughout the unit—look for sign near water sources.

Bison and elk are historically present but less common in this lower-elevation landscape. The Colorado River corridor holds year-round water and concentrates wildlife; water access points become high-percentage areas.
