Unit 682
High-plains ranch country with scattered lakes and irrigation ditches near the San Luis Valley.
Hunter's Brief
Unit 682 is open, manageable terrain at moderate elevation—ranches and grasslands with scattered cottonwood draws and irrigation infrastructure. Bounded by US 285 and Colorado 17, it's straightforward to access and navigate. Water comes from ditches and lakes rather than flowing creeks, making those features critical to hunting strategy. Low terrain complexity means pressure tends to concentrate around obvious access points; hunting edges and less-obvious country pays off here.

Landmarks & Navigation
The North Branch Saguache Creek and Russell Creek provide major drainage corridors and water reference points. Russell Lakes, Davey Lake, and several smaller named lakes dot the unit and serve both as water sources and navigation landmarks. Extensive irrigation ditches—including the Gotthelf Samora, Roberts Company, Phillips, and Campbell systems—crisscross the country and should be treated as navigation features rather than obstacles.
Rattlesnake Hill and the various gulches (Big Hollow, Schecker, De Tilla) offer minor elevation changes useful for glassing and orientation.
Elevation & Habitat
The unit maintains consistent medium elevation across relatively flat to gently rolling terrain—no dramatic mountains, no deep canyons. Vegetation is predominantly short grass prairie and sagebrush interspersed with scattered stands of cottonwood and willows along creeks and ditches. The sparse forest coverage means open country dominates, offering good visibility for glassing but limited thermal cover.
This is classic high-plains habitat where shelter comes from creek bottoms, willow thickets, and occasional ridge edges rather than timber.

Start free trial ›Access & Pressure
Fair road access via US 285 and Colorado 17 means most hunters park near highways and work inward. The straightforward terrain and moderate complexity concentrate pressure around obvious entry points and water features. The sparse road network within the unit means once you're in, navigation is relatively simple but cross-country travel is unavoidable.
Private land interspersed with public access means careful boundary attention. Midweek hunting and exploring away from ditch crossings and obvious water sources should find lighter pressure.
Boundaries & Context
Unit 682 sits in Saguache County in Colorado's San Luis Valley, hemmed in by US 285 on the north and west, Colorado 17 on the east, and County Road G on the south. This moderate-sized unit occupies relatively accessible valley floor and gentle upland country typical of Colorado's ranching region. The surrounding landscape is working ranch land and private holdings, making boundary awareness essential.
The nearby towns of Saguache and Moffat serve as reference points for orientation and logistics planning.
Water & Drainages
Water here is primarily managed rather than wild—irrigation ditches form the primary water network across the unit. Russell Lakes, Davey Lake, and Kimmel Lake provide reliable surface water, though seasonal conditions matter. North Branch Saguache Creek and Russell Creek flow seasonally and shouldn't be assumed reliable mid-summer.
Ball Arroyo drains the southern portion. Hunters should map ditch systems and lakes before entry; understanding water distribution is essential for hunting pressure avoidance and animal movement prediction on this relatively open ground.
Hunting Strategy
Elk, mule deer, white-tailed deer, and pronghorn are the primary species; moose occur but are uncommon. The open prairie and scattered cottonwood habitat favors glassing—use elevation changes and ridge edges to scan country before committing. Early season hunting focuses on creek drainages and willow thickets where animals concentrate near water.
Rut timing (fall) can push elk and deer to slightly higher country seeking buttes and ridge systems. Pronghorn hunting works the open flats. Water scarcity mid-season means lakes and ditches become focal points; approach these carefully during midday heat.
Low terrain complexity means stealth and wind matter more than terrain navigation.
