Unit 100
WASHINGTON/MORGAN
High plains grassland boxed by highways with scattered creeks and minimal timber.
Hunter's Brief
Unit 100 is straightforward high plains country—rolling grassland with minimal forest cover between 4,200 and 5,000 feet. Well-connected by county and state roads, with small reservoirs at Akron and scattered creek drainages providing occasional water. Access is fair and pressure tends to concentrate near towns like Anton and Akron. The low terrain complexity and sparse cover make it readable country, though water scarcity and limited shade can challenge mid-day hunting.

Terrain Deep Dive
Landmarks & Navigation
Akron Reservoir and Akron-Washington Company Recreation Reservoir provide reliable reference points and potential water sources near the unit's center. Sand Creek and Plum Bush Creek with its east and west forks offer the most significant drainage systems for navigation and water access. Vega Creek, Buck Creek, and Antelope Creek provide secondary orientation features.
Shears Draw and Dry Gulch are shallow features useful for travel corridors. Haverland Pond rounds out the water options, though seasonal reliability varies.
Elevation & Habitat
The unit spans just 775 feet of elevation, hovering in the low plains between 4,200 and 5,000 feet. Habitat is predominantly open grassland and prairie with sparse juniper and ponderosa stands. Sagebrush and native shortgrass dominate the landscape, offering excellent visibility but limited thermal cover.
The flatness and minimal tree canopy mean conditions change little with elevation—hunters move through consistent prairie broken occasionally by shallow drainages and scattered canyons.
Access & Pressure
Over 1,500 miles of county and state roads web through the unit, making it highly accessible by vehicle. The connected road network means most areas are within a short drive from staging towns. This accessibility concentrates pressure around populated areas—Anton and Akron draw most early-season hunting activity.
The flat, open terrain offers little refuge, so pressure spreads quickly once hunters find animals. Back roads and less obvious creek drainages see lighter pressure, but the low complexity and readable country mean solitude is limited.
Boundaries & Context
Unit 100 occupies the northern Colorado plains spanning Washington and Morgan counties. U.S. 34 forms the northern boundary, with Colorado 61 bounding the east side, U.S. 36 marking the south, and Colorado 71 running along the west. This arrangement places the unit squarely in the transition between the Front Range foothills and the eastern plains, with several small towns—Anton, Akron, Last Chance—providing logistics support.
The unit sits at the edge of where irrigated agriculture gives way to rangeland.
Water & Drainages
Water is the limiting factor in Unit 100. Akron Reservoir and the companion recreation reservoir are the most reliable sources, making them focal points for planning. Plum Bush Creek and its forks offer seasonal flows depending on snowmelt and recent precipitation. Sand Creek, Vega Creek, and Antelope Creek run intermittently through the grasslands—wet during spring runoff, questionable by mid-summer.
Most drainages are shallow gullies rather than perennial streams. Hunters must plan water carries and time travel to creek systems accordingly.
Hunting Strategy
Unit 100 supports mule deer, white-tailed deer, pronghorn, elk, and moose, with occasional black bear and mountain lion. The open prairie favors pronghorn hunting early season when water is available and visibility is maximum. Mule deer concentrate near creek bottoms and sparse timber; white-tails use the same riparian cover.
Elk are present but sparse in this unit—focus on creek drainages where cottonwoods provide cover. Early morning glassing from ridges overlooking Plum Bush and Sand Creek valleys works well. Late season pressures animals toward water sources and creek systems where thermal cover is heaviest.
