Quick Tips
GPS or a compass will be a necessity at all times in this unit
Can be rugged and steep terrain in some area should only be traversed by those experienced in similar areas; trekking poles should be brought
Getting in touch with the local biologist prior to your hunt will help considerably; these sheep are monitored regularly and the biologist can help point you in the right directions prior to heading into the unit
There is very little water available on this unit once you leave the river, so take as much as you can pack when you leave your vehicle
Remember to have a solid plan around anchoring the boat once you have crossed the river, keep in mind that the level of the water in the river fluctuates during the day due to the reservoir
The L.T. Murry and Colockum Wildlife Areas make up the bulk of this area, located in the southern portion of the Quilomene Bighorn sheep unit in Washington. The majority of the sheep in this unit are typically found along the Columbia River, or within two miles of the river up the many different canyons and drainages that come from the west. This is a very broken unit, once you leave your vehicle expect a very serious hike, even if it’s short. Most people choose to hunt from the Columbia River, and once a ram is located they anchor up and climb the mountains and canyons to the west.
The majority of the sheep in this unit tend to hang either just above the river or as much as 2 miles away, up some of the deeper canyons in the L.T. Murry Wildlife Area. There have been some reports of sheep in the high bluffs, south of Colockum Creek, pre-rut.
