Colorado Pronghorn Mule Deer

Unit 107 (Hugo / Kiowa Plains)

Colorado Hunting Guide — Pronghorn, Mule Deer

Unit 107 lies in Washington, Lincoln and Kit Carson counties and covers about 1,240 square miles. Ground runs from 4,584 to 5,554 feet. CPW bounds it by U.S. 36 and Colo. 59 among others. CPW's harvest estimates put pronghorn success here as high as 62%. No federal land falls inside it, so every acre is a permission question. Check land status on a current map before you plan a route.

Pronghorn Hunting in Unit 107

Where to Find Pronghorn in Unit 107

CPW draws an exact line around unit 107 and says nothing about where the pronghorn stand inside it. The country below is verified; where to begin in it is our judgement, not the agency's. The unit lies in Washington, Lincoln and Kit Carson counties. It runs to about 1,240 square miles.

The lines of the unit: U.S. 36, Colo. 59 and Colo. 71

CPW has unit 107 bounded on the north by U.S. 36; on the east by Colo. 59; on the south by I-70; on the west by Colo. 71. It tells you the shape of the unit and nothing about its inhabitants. Its value is practical — those are the features you will navigate by, and the ridges that separate one day's country from another's.

Public ground to start from: Flagler Reservoir SWA and Flagler STL

CPW lists Flagler Reservoir SWA and Flagler STL inside this unit as ground open to public hunting. Each property sets its own restrictions, and the agency's page for it is where they are written down. Federal land covers about 0% of the unit on top of those.

Water: Lusto Springs

The water inside the unit line comes to 68 mapped stream reaches, 1 lakes and 136 stock tanks. Named sources include Lusto Springs. On ground with that many tanks, knowing which two or three hold water in your season is the most useful thing a scouting trip can tell you.

The herd this unit belongs to: A-19

CPW does not manage pronghorn unit by unit. It manages them as data analysis unit A-19, and unit 107 is one piece of it. The rest of A-19 is unit 103, unit 106 and unit 109. Read a neighbour in the same herd before you read the state average — the herd, not the unit line, is what the agency is steering.

What is published about unit 107, and what is not

The public datasets name only 3 features inside this unit. That is the finding. Ground this size held privately is farmed and grazed rather than mapped, and the hunt starts as a conversation with a landowner rather than a route. Work out who owns the ground first, then ask. What the unit does have is 1,240 square miles of it, and the pronghorn living on it are there whether or not anyone has mapped a name onto the ground. Pronghorn live in the open and trust their eyes, which is the whole problem.

Reading the land status

Our ownership read for this unit is approximate — it comes out as Private / Other 85% and BLM 15%, so treat it as a starting point and check a current land-status layer before you plan a route. A grid sample of the unit reads 4,584 to 5,554 feet, averaging 5,059 — a sample rather than a survey, so read the ends as approximate. There is not much relief, so the animals move laterally rather than up and down.

The lay of it

1,240 sq mi inside the boundary. Big enough that picking one drainage beats driving three.

Who owns the ground

BLM — 15%
Private / Other — 85%

Roughly 15% is public. Carry a land-status layer anyway — these are area percentages, not a map of where the boundaries fall.

Water on the ground

Counts from mapping data, so this is how many exist, not how many hold water in a dry year. Sitting water only pays where you find fresh tracks.

Every one of these was tested against the unit polygon before it went on the map. They are starting points, not agency recommendations.

How to Hunt Pronghorn in Unit 107

CPW's own harvest estimates put pronghorn success in unit 107 at 62% across all manners of take. A number like that comes from few tags and a short season, not from easy hunting. The plan: spot from a vehicle or a rise at distance, then plan a stalk that uses the only cover there is — the curve of the ground.

Finding a view in unit 107

No named high ground falls inside this unit, which changes the method rather than ruling it out. Use the edges instead of the elevation — a field margin, a shelterbelt, the lip of a draw. Pronghorn live in the open and trust their eyes, which is the whole problem. Cover ground slowly and stop more often than feels sensible.

Water against feed

There are 68 mapped stream reaches and 136 tanks inside the unit, so water is rarely the limiting factor. Where water is everywhere, feed is what concentrates animals, so hunt the feed and treat water as a convenience. Check the ground around it before you commit an evening to it.

Timing the season: Sep, Oct, Nov

Season normals here run Sep 79/47°F, Oct 65/34°F and Nov 52/23°F. Warm afternoons compress the hunting into the first and last hour, and make meat care the day's real problem rather than the shot. Precipitation runs about 1.2 in. in Sep, 1.2 in. in Oct and 0.5 in. in Nov, and the graded gravel in this unit turns greasy wet.

Getting past the roads: I 70 and County Road 3X

I 70, US 36 and CO 59 / CR 15 are the paved frame, which is also where everyone else starts. There is little true four-wheel-drive road here, so distance from the gravel is the only thing separating you from the next hunter. 6 mapped public entry points fall inside the unit, so decide which one you take before the morning you take it.

Where unit 107 sits inside A-19

Across A-19, CPW's 2023 pronghorn success runs 62% in unit 107, 60% in unit 106 and 51% in unit 109. Unit 107 is the best of them on that measure, which usually means fewer tags rather than more animals. Success inside one herd moves with tag numbers and season length as much as with animals, so read the licence count alongside it.

A first plan from the pins on this page

The map above marks Flagler Reservoir SWA, Flagler STL, Walk-In Access 10 — C and Walk-In Access 11 — C as ground to watch. Each pin is a named feature verified to fall inside the unit line, not a spot anyone has hunted. Take the pair you can reach on one road and treat the rest as a second trip.

What a day here costs you

1,240 square miles is more country than a week will cover, so pick one drainage and learn it rather than driving the unit. The nearest services are at Arriba, about 15 miles out, which is an hour of your morning each way if you sleep there. The ground is gentle enough that the pack-out is a distance problem rather than a climbing one. Leave the truck earlier than you want to and you will hunt the best half-hour of the day.

Colorado rules that decide your day

Summarised from CPW regulations. They change — read the current regulations and your permit-tag before you hunt.

Legal shooting hours

Big game may be taken from half an hour before sunrise to half an hour after sunset.

Motorized retrieval

Colorado has no general off-road retrieval allowance. Travel stays on designated routes, so plan to pack every animal out on your back or with stock. Check the forest or BLM travel map for the roads that are actually open in hunting season.

Tagging

Validate and attach your carcass tag before the animal is moved, and keep evidence of sex attached until the carcass reaches your home or a processor.

Leaving meat

Abandoning edible meat is illegal. CPW counts the four quarters and the loins.

Where you may not shoot

Occupied structures — No discharging a firearm within 50 yards of a developed campsite, and never toward an occupied building.
Roads — No shooting from or across a public road, and no shooting from a motor vehicle.

Pronghorn: where to put the shot

Broadside, straight up the front leg, a third of the way into the body. Pronghorn are shallow-chested and the lungs sit forward.

Shots to refuse

Range it, then range it again. Open country makes 400 yards look like 250.
Wait for the buck to stop. Nobody kills a running pronghorn cleanly on purpose.
Mind the backdrop. A miss carries a long way across a flat.

Plan the carry: roughly 30– 45 lb of boned-out meat, before head and hide — one large cooler with ice already in it. ProHunt planning estimate, not an agency figure.

Pronghorn Success Rates

All manners of take62%

CPW's 2023 harvest estimates put pronghorn success in unit 107 at 62% — 180 animals taken by 292 hunters. The hunter count is large enough for the percentage to mean something and small enough that a good or bad year still moves it.

These are the agency's own printed figures for this unit, not a modelled estimate and not a state average. They describe one season, so check CPW's current harvest estimates before you read a trend into them.

Mule Deer Hunting in Unit 107

Unit 107 lies in Washington, Lincoln and Kit Carson counties and covers about 1,240 square miles. Ground runs from 4,584 to 5,554 feet. CPW bounds it by U.S. 36 and Colo. 59 among others. CPW's harvest estimates put mule deer success here as high as 40%. No federal land falls inside it, so every acre is a permission question. Check land status on a current map before you plan a route.

Where to Find Mule Deer in Unit 107

CPW's material on unit 107 stops at the boundary — there is no agency account of where its mule deer live. Every place named below sits inside the unit line. Which of them holds animals in your season is for you to find out. The unit lies in Washington, Lincoln and Kit Carson counties. It runs to about 1,240 square miles.

The lines of the unit: U.S. 36, Colo. 59 and Colo. 71

CPW has unit 107 bounded on the north by U.S. 36; on the east by Colo. 59; on the south by I-70; on the west by Colo. 71. That is a legal description, not a habitat map. Those features are what you will check against the map all week, and the divides among them are the ones that matter.

Public ground to start from: Flagler Reservoir SWA and Flagler STL

Water: Lusto Springs

The herd this unit belongs to: D-46

CPW does not manage mule deer unit by unit. It manages them as data analysis unit D-46, and unit 107 is one piece of it. The rest of D-46 is unit 112, unit 113, unit 114, unit 115, unit 120 and unit 121. So the objective behind your tag was written for that whole area, and a neighbouring unit in the same herd is a fairer comparison than the statewide figure.

What is published about unit 107, and what is not

The public datasets name only 3 features inside this unit. That is the finding. Ground this size held privately is farmed and grazed rather than mapped, and the hunt starts as a conversation with a landowner rather than a route. Work out who owns the ground first, then ask. What the unit does have is 1,240 square miles of it, and the mule deer living on it are there whether or not anyone has mapped a name onto the ground. Mule deer on open country use every fold and draw there is, and almost none of the flat.

How to Hunt Mule Deer in Unit 107

CPW's own harvest estimates put mule deer success in unit 107 at archery 33% and rifle 40%. That is an ordinary spread for this country, and it rewards whoever scouted. The plan: glass the broken edges at first light, then sit still and keep glassing the same ground.

Finding a view in unit 107

No named high ground falls inside this unit, which changes the method rather than ruling it out. Height comes from the vehicle or from a bank above a watercourse, and either is enough at first light. Mule deer on open country use every fold and draw there is, and almost none of the flat. Cover ground slowly and stop more often than feels sensible.

Water against feed

There are 68 mapped stream reaches and 136 tanks inside the unit, so water is rarely the limiting factor. Where water is everywhere, feed is what concentrates animals, so hunt the feed and treat water as a convenience. Sitting water works where you can see fresh tracks going in, and nowhere else.

Timing the season: Sep, Oct, Nov

Getting past the roads: I 70 and County Road 3X

Where unit 107 sits inside D-46

Across D-46, CPW's 2023 mule deer success runs 41% in unit 112, 40% in unit 107, 40% in unit 114, 37% in unit 120 and 25% in unit 113. That puts unit 107 behind 1 of the 4 other units in the herd. If the draw lets you choose, unit 112 carried the better number in the same herd — check its tag count before you read that as an easier hunt.

A first plan from the pins on this page

The map above marks Flagler Reservoir SWA, Flagler STL, Walk-In Access 10 — C and Walk-In Access 11 — C as ground to watch. Each pin is a named feature verified to fall inside the unit line, not a spot anyone has hunted. Walk between two of them rather than driving between four, and you will learn more in a day.

1,240 square miles is more country than a week will cover, so pick one drainage and learn it rather than driving the unit. The nearest services are at Arriba, about 15 miles out, which is an hour of your morning each way if you sleep there. The ground is gentle enough that the pack-out is a distance problem rather than a climbing one. One good position held through the whole of first light beats three visited in a hurry.
