🐟 Season Dates & Bag Limits
| Species | Season | Bag Limit | Size Limit | Notes |
|---|---|---|---|---|
| Rainbow / Brown / Brook Trout | Year-round (most waters) | 8/day | None statewide (Gold Medal Waters and special regulation waters differ) | Bag of 8 trout in aggregate on most waters. Gold Medal Waters have 2-fish limit and 16-inch minimum. Always check specific water body rules. |
| Cutthroat Trout | Year-round (most waters) | 2/day | None (varies by water) | Colorado cutthroat trout are a conservation priority. Many waters require catch-and-release or have very restrictive limits. See CPW. |
| Largemouth / Smallmouth Bass | Year-round | 5/day | 15 inches minimum | Bass are not native to Colorado but are widely stocked in warm-water reservoirs |
| Walleye | Year-round | 5/day | 15 inches minimum | Pueblo Reservoir and John Martin Reservoir are top walleye destinations |
| Yellow Perch | Year-round | No statewide limit | None | Excellent for ice fishing in winter. Plan by waterbody in Colorado, since local chapters and seasonal access details can differ significantly. |
| Northern Pike | Year-round | 5/day | None statewide | Native to some eastern Colorado rivers; also stocked in reservoirs |
| Tiger Muskie | Year-round (some waters) | No limit on designated waters (North Fork of Colorado River, Grand Lake area) | None on designated waters (2026 change) | NEW in 2026: No size, bag, or possession limits for tiger muskie in North Fork of Colorado River, Shadow Mountain Spillway, Grand Lake, and Lake Granby. |
| Kokanee Salmon | Year-round (most waters) | 10/day | None | Landlocked sockeye salmon found in Eleven Mile Reservoir, Dillon Reservoir, Blue Mesa Reservoir, and others. Fall (Sept–Nov) spawning run up inlet streams is exciting and accessible fishing. Light tackle and small spinners/spoons work well. |
| Channel Catfish | Year-round | 10/day | None | Warm-water reservoirs in eastern Colorado and along river corridors |
