Unit Old Naches

Wenas Creek and the Tieton River serve as major natural corridors through the unit, with Tieton draining from the southeast and multiple creek systems (Cowiche, Spring, Wenas, Cottonwood) providing water and travel routes. Wenas Valley to the south and Evans Canyon to the north offer key glassing benches and access points. Union Gap marks a significant drainage confluence worth noting for navigation.

Several reservoirs—Parker, Wenas Lake, Rotary Lake—provide reliable water and often concentrate hunting activity nearby. Pleasant Hill and Wenas Mammoth Mountain serve as reference points for orientation on the higher ridgelines.

The unit spans low foothills and valley floors, bottoming out around 925 feet in the major river valleys and rising to roughly 3,000 feet on the higher ridgelines. This elevation range keeps the landscape in transition country—ponderosa pine and Douglas-fir scatter across south-facing slopes and ridges, while sagebrush, bitterbrush, and grassland dominate open flats and north-facing aspects at lower elevations. The sparse forest cover means big blocks of open country for glassing, with timber concentrated in canyon bottoms and shaded draws.

Aspen and cottonwood appear in riparian zones along creeks and seeps.

A connected road network means easy access from Yakima and surrounding towns, with multiple highway corridors entering the unit. This accessibility creates moderate hunting pressure, particularly on opening weekends and from local hunters. Most roads lead to ranch gates or dead-end in canyon bottoms, so foot traffic concentrates near obvious access points and water sources.

Quieter hunting typically requires getting off main drainages and climbing ridges away from creek bottoms where roads end. The moderate size and accessible roads mean the unit fills up quickly during prime seasons, especially early elk season.

Old Naches occupies the foothills immediately west and southwest of Yakima, anchored by the Tieton and Naches river drainages that define much of the unit's character. The landscape sits in the rain shadow of the Cascade Range, resulting in drier conditions and sparser forest than higher country to the east. Populated areas like Yakima, Tieton, and Tampico border the unit, with Wenas Valley to the south and various canyon systems carved by seasonal and perennial streams.

The unit's moderate size and lower elevation make it accessible year-round, though private land interspersed throughout limits some hunting options.

Water availability is moderate but seasonal in spots—the Tieton and Naches rivers run year-round, while several creeks (Cowiche, Spring, Wenas, Cottonwood) provide reliable flow. Spring Creek and its forks offer accessible water in the northern sections. Several reservoirs including Parker Reservoir, Wenas Lake, and Rotary Lake create reliable water sources that often concentrate wildlife.

Drier ridges and benchlands away from drainages require planning for water access. The system of lateral ditches and canals serving agricultural areas means some water availability in lower elevations but also indicates mixed public/private land patterns.

Old Naches is primarily elk country across its foothills and canyons, with limited high-country refuge. Early season hunting focuses on ridgelines and open slopes where thermal cover remains sparse; bulls work the scattered timber and spend mornings on open aspects. As weather cools, elk migrate slightly higher into canyon bottoms where aspen and heavier timber offer security.

Rut hunting means glassing parks and open flats early and late, then pursuing bugling bulls in canyon systems. Water sources attract elk, making reservoirs and reliable creeks key focal points. Success depends on accessing terrain away from the most obvious entry points and being willing to hunt steep canyon walls where foot pressure is lighter.
