Understanding Colorado's Gold Medal Trout Waters
What Makes a Gold Medal Water?
Gold Medal designation represents Colorado's highest standard for public fishing waters. The Colorado Wildlife Commission awards this prestigious title only to waters meeting stringent biological benchmarks.
To qualify, waters must sustain 60 pounds of trout per surface acre, with at least 12 quality trout (14 inches or larger) per acre. Additionally, the water must offer public access and span minimum distances - two miles for streams or 50 acres for lakes.
These exceptional fisheries result from optimal habitat conditions, careful management, and often special regulations. Understanding these standards helps anglers appreciate why Gold Medal Waters consistently produce memorable fishing experiences.
Gold Medal vs Hidden Gem Fishing Spots
Choosing between Gold Medal Waters and lesser-known streams involves weighing several factors. Gold Medal Waters guarantee high fish densities and trophy potential but often attract significant angling pressure, especially on weekends.
Hidden gems offer solitude and wild trout in pristine settings. While fish densities may be lower, these waters provide intimate angling experiences and often surprise with quality fish. Many locals prefer these quieter options for regular outings.
Consider Gold Medal Waters when seeking consistent action and trophy opportunities. Choose hidden gems for solitude, scenic beauty, and the satisfaction of discovering productive water through exploration.

Colorado River Fishing Season Guide
Spring (March-May)
Spring Colorado river fishing season brings both challenges and opportunities. March often sees excellent midge fishing on tailwaters while freestone rivers remain frozen. April initiates pre-runoff fishing with Blue Wing Olives providing consistent action.
May marks transition as snowmelt begins affecting river flows. Lower elevation waters fish well early in the month before runoff peaks. Tailwaters below dams maintain fishable conditions throughout spring.
Focus efforts on regulated flows below reservoirs during peak runoff. The Arkansas River below Pueblo Reservoir and the Colorado below Windy Gap fish well when other waters blow out.
Summer (June-August)
Summer transforms Colorado's fishing landscape as high country waters become accessible. June sees runoff declining, with rivers clearing from downstream up. By July, most waters fish well with excellent hatches.
August brings terrestrial season with hoppers, ants, and beetles producing aggressive strikes. High country lakes and streams reach peak conditions. Evening hatches of caddis and mayflies provide excellent dry fly fishing.
Mountain weather brings afternoon thunderstorms, making morning fishing preferable. Water temperatures can stress trout during hot spells, so fish early and give warm water a break.
Fall (September-November)
Fall delivers Colorado's most consistent fishing conditions. September continues excellent dry fly fishing with reduced crowds. October triggers pre-spawn aggression in brown trout, making streamer fishing exceptional.
November brings winter's approach, concentrating fish in deeper pools. Blue Wing Olives provide reliable hatches on mild days. Fall colors enhance already spectacular mountain scenery.
Weather becomes increasingly unpredictable, requiring layered clothing. Snow can arrive anytime at elevation, potentially closing high country access roads.
Winter (December-February)
Winter fishing rewards hardy anglers with solitude and surprising action. Tailwaters fish best, maintaining consistent temperatures when freestone rivers ice over. South Platte Canyon sections and the Arkansas below Pueblo provide reliable options.
Midge fishing dominates winter tactics. Fish concentrate in deeper, slower pools. Midday fishing produces best when water temperatures peak. Dress warmly and watch for ice shelves.
Many high elevation waters become inaccessible. Check road conditions before traveling. Winter's challenges are offset by exceptional fishing for those willing to brave cold conditions.
Essential Gear for Colorado Trout Fishing
Fly Fishing Setup
Colorado's diverse waters demand versatile fly fishing equipment. A 9-foot, 5-weight rod handles most situations from small streams to larger rivers. Pack a 3-weight for technical spring creeks and a 6-weight for streamer fishing.
Essential Fly Patterns:
- Dry Flies: Parachute Adams, Elk Hair Caddis, Stimulator
- Nymphs: Pheasant Tail, Prince, Copper John
- Streamers: Woolly Bugger, Sculpzilla
- Terrestrials: Hoppers, Ants, Beetles
Leaders should range from 7.5 to 12 feet, with tippet from 3X to 6X. Fluorocarbon tippet improves success in clear water. Strike indicators, split shot, and floatant complete the basic setup.
Spin Fishing Tackle
Spin fishing effectively targets Colorado trout, especially in high water. Ultra-light setups with 4-6 pound test line handle most situations. Medium-light gear works better for larger rivers and fish.
Productive Lures:
- Kastmaster spoons (1/8 to 1/4 ounce)
- Panther Martin spinners (sizes 2-6)
- Rapala Original Floater (F3-F5)
- PowerBait (where allowed)
Focus on natural colors like gold, silver, and rainbow patterns. In clear water, downsizing improves success. Add split shot above lures to reach deeper pools.

Purchase licenses online through Colorado Parks and Wildlife or at license agents statewide. Habitat stamps are required in addition to licenses. Keep licenses readily accessible while fishing.
Special Regulations by Water
Gold Medal Waters often implement special regulations protecting fish populations. Common restrictions include artificial flies and lures only, catch and release sections, and slot limits.
Always check current regulations before fishing. Regulations change periodically based on population assessments. Some waters have seasonal closures protecting spawning fish. Private property boundaries require careful attention.
Download the Colorado Fishing App for convenient regulation access. The app provides GPS-enabled regulation information for your specific location.
Pro Tips for Fishing Colorado's Streams
High Altitude Considerations
Colorado's elevation significantly impacts fishing success and safety. Altitude sickness affects many visiting anglers, especially those arriving from sea level. Allow time for acclimatization before strenuous wading.
Sun intensity increases with elevation, making protection essential. Wear sunscreen, polarized glasses, and protective clothing. Dehydration occurs quickly in dry mountain air, so pack plenty of water.
Weather changes rapidly in mountains. Afternoon thunderstorms develop quickly during summer. Lightning poses serious risks on open water, so monitor conditions and seek shelter when storms approach.
Reading Mountain Water
Success in Colorado streams requires understanding mountain water characteristics. Trout seek three elements: food, shelter, and comfortable current. Identify areas providing all three for consistent success.

- Seams between fast and slow currents
- Pocket water behind boulders
- Deep pools and runs
- Undercut banks
- Tributary confluences
High gradient streams concentrate fish in specific lies. Low water reveals structure that holds fish at all levels. Study water during low flows to understand year-round holding areas.
Matching the Hatch
Colorado's diverse waters support numerous aquatic insects. Understanding major hatches improves success dramatically. Carry basic patterns in various sizes rather than exact imitations.
Major Colorado Hatches:
- Blue Wing Olives: Spring and fall (sizes 18-22)
- Caddis: Mother's Day through summer (sizes 14-18)
- Pale Morning Duns: June-July (sizes 16-18)
- Tricos: July-September mornings (sizes 20-24)
- October Caddis: Fall (sizes 8-10)
Observe naturals and trout feeding behavior. Match size first, then profile, then color. When nothing hatches, attractor patterns often produce curious strikes.
Planning Your Colorado Fishing Trip
Best Times to Visit
Timing Colorado fishing trips requires balancing conditions, crowds, and target species. July through September offers most consistent conditions across all elevations. October provides exceptional fishing with fall colors.
Avoid holiday weekends when possible. Midweek fishing means fewer crowds at popular destinations. Early season requires flexibility as runoff timing varies annually.
Consider targeting specific hatches or seasonal opportunities. Research historical timing but remain flexible as conditions vary yearly. Local fly shops provide current conditions and recommendations.
Lodging & Guide Services
Colorado offers accommodations from primitive camping to luxury resorts. Mountain towns near fishing destinations provide various options. Book early for peak season, especially in tourist areas.
Hiring guides accelerates learning curves on new waters. Experienced guides provide access to private water and share local knowledge. Float trips with guides access otherwise unreachable water.
Research guides specializing in your target waters and techniques. Read reviews and ask about included services. Many lodges offer guide services creating convenient fishing packages.
Local Fly Shops
Fly shops provide invaluable local knowledge and current fishing reports. Stop in before fishing new waters for recommendations on flies, techniques, and access.
Shop staff often guide locally, providing expert insights. Purchase flies and supplies locally to support businesses that maintain fishing access. Many shops offer guide services and casting lessons.
Build relationships with shop staff for ongoing intelligence. They appreciate feedback on your fishing experiences, creating mutually beneficial exchanges.
Conservation & Responsible Fishing
Catch & Release Best Practices
Proper catch and release ensures healthy fish populations for future anglers. Use barbless hooks or crimp barbs to facilitate easy release. Fight fish quickly to minimize exhaustion.
Keep fish in water whenever possible. Wet hands before handling to protect slime coats. Support fish horizontally, never vertically. Remove hooks gently using forceps or pliers.
Water temperature affects survival rates. When water exceeds 68°F, consider fishing elsewhere. Revival requires holding fish facing current until they swim away strongly.
Leave No Trace Principles
Responsible anglers protect resources for future generations. Pack out all trash, including monofilament line. Respect private property and obey posted signs.
Stay on designated trails to prevent erosion. Cross streams at established points. Avoid disturbing spawning redds, appearing as clean gravel patches.
Wildlife encounters require appropriate responses. Never feed wildlife. Store food properly in bear country. Give animals space, especially during spring when young are present.
