Colorado Fishing Laws and Regulations

Colorado manages hundreds of distinct lakes, reservoirs, and river reaches, and a rule that applies on a stocked valley pond at Corn Lake can be completely different from a Gold Medal tailwater below Ruedi or a trophy pike reservoir like Rifle Gap.

Why We Link Directly to CPW Regulations

Rather than pasting static bag limits onto our website that could go out of date when Colorado Parks and Wildlife (CPW) issues an emergency low-flow closure or updates a slot limit, we point every angler straight to the primary source:

• Official CPW Fishing Regulations Brochure: Look up your exact river section or reservoir in the alphabetical special-regulations index before you leave the driveway.
• CPW Fishing Licenses & Habitat Stamp: Required for anglers age 16 and older (April 1 through March 31 license year).
• CPW Colorado Fishing Atlas: Interactive state map showing Gold Medal waters, Wild Trout streams, and public State Wildlife Area (SWA) boundaries.

Four Things to Check Before Every Western Slope Trip

1. Tackle & Bait Rules: Check whether your water allows bait or requires artificial flies and lures only (and whether scented soft plastics count as bait under CPW definitions).
2. Species Slot & Bag Limits: Waters like Rifle Gap (walleye), Blue Mesa (lake trout and kokanee), and the Gunnison River have water-specific size and harvest rules in the brochure.
3. Second-Rod Stamp & Ice Holes: Verify current CPW rules on using a second rod and maximum ice-hole diameter before drilling on frozen reservoirs.
4. State Park & SWA Access Rules: State Parks require a valid vehicle park pass, and many State Wildlife Areas require a valid hunting or fishing license for everyone entering the property.
