Ice fishing is a cherished winter tradition in Colorado, offering anglers the opportunity to enjoy the serene beauty of frozen lakes and reservoirs while catching fish through the ice. However, like any outdoor activity, ice fishing comes with rules and regulations to ensure safety, protect the environment, and sustain fish populations for future generations. Here's what you need to know about the rules for ice fishing in Colorado.

1. Ice Fishing License Requirements

Before you head out to the ice, make sure you have a valid Colorado fishing license. Licenses are required for anyone 16 years of age or older. You can purchase a license online, through the Colorado Parks and Wildlife (CPW) website, or at local retailers.

Important Notes:

• Residents and non-residents are both required to have a license.

• Colorado offers one-day, five-day, and annual licenses.

• All anglers must also possess a Habitat Stamp if purchasing a fishing license for more than one day.

2. Ice Safety Guidelines

Colorado Parks and Wildlife does not monitor ice thickness, so anglers must evaluate ice conditions themselves. Following these safety guidelines is crucial:

• Minimum Ice Thickness: Ensure ice is at least 4 inches thick for walking, 6-8 inches for ATVs or snowmobiles, and 12-15 inches for larger vehicles.

• Test the Ice: Drill test holes with an auger or spud bar as you proceed to ensure consistency in thickness.

• Carry Safety Equipment: Bring ice picks, rope, a flotation device, and a buddy to stay safe in case of an emergency.

3. Bag and Possession Limits

Bag and possession limits vary depending on the species and location. Always consult the latest Colorado Fishing Regulations Brochure, available on the CPW website or at local shops, to stay compliant.

Common Limits:

• Trout: The statewide daily bag limit is four trout, with a possession limit of eight.

• Kokanee Salmon: Daily bag limit is 10, possession limit is 20 in most waters.

• Pike and Walleye: Some locations encourage harvesting of northern pike and walleye to control populations, with no bag limits in certain reservoirs.

4. Bait and Tackle Regulations

Colorado has specific rules about the types of bait and tackle you can use for ice fishing:

• Live Bait: Live fish as bait are prohibited in most Colorado waters. Instead, use commercially purchased or legally caught aquatic bait such as worms, minnows, or salmon eggs.

• Artificial Lures: Use artificial lures or flies in waters designated as "Artificial Fly and Lure Only" areas.

• Tip-Ups: Anglers can use multiple lines with tip-ups, but each line must be labeled with the angler's name and CID number.

5. Specific Lake and Reservoir Rules

Certain lakes and reservoirs in Colorado have unique rules for ice fishing. For example:

• Granby Lake: Known for its large lake trout, Granby allows ice fishing, but anglers should review seasonal closure areas.

• Antero Reservoir: Offers excellent ice fishing opportunities for trout, with limits based on CPW regulations.

• Eleven Mile Reservoir: A popular spot for trophy trout, northern pike, and kokanee, it has designated access points and safety advisories.

Check local regulations and posted signs before fishing, as they may outline additional restrictions or guidelines.

6. Stay Mindful of Wildlife

Colorado’s ice-fishing locations are often home to diverse wildlife. Keep a safe distance from animals, avoid disturbing habitats, and pack out all trash to preserve the natural beauty of the area.

7. Accessibility and Permits

Some lakes and reservoirs may require a day-use permit or an additional fee to access certain facilities. These permits often help fund maintenance and conservation efforts. Check with the local managing authority for details.

8. Observe Seasonal Closures

Certain waters in Colorado have seasonal closures to protect fish during spawning periods. Always review the CPW's most recent fishing regulations to confirm whether the lake or reservoir you plan to visit is open for ice fishing.
