Fly fishing for musky, particularly tiger muskie, in Colorado is an exhilarating challenge. Known as the "fish of ten thousand casts," muskies are apex predators, offering a unique angling experience in the state. Though they are not native to Colorado, tiger muskies have been stocked in various lakes and reservoirs to manage sucker populations, creating incredible opportunities for anglers to target this rare species.

Where to Find Musky in Colorado
Some of the best locations for musky fishing in Colorado include:
- Gross Reservoir
- Evergreen Lake
- Pinewood Reservoir
- Lower Big Creek Lake
These lakes provide optimal habitats for tiger muskies, which thrive in deeper waters near weed beds, drop-offs, and rocky structures

Best Times and Conditions to Fish for Musky
Musky fishing in Colorado reaches its peak productivity during the late summer and early fall months, with August and September being particularly favorable. During this period, the water temperatures are just right, creating an environment where muskies become more active and can be found in shallower waters. This is because they are feeding heavily on baitfish, which are more abundant and accessible in these areas.
The cooler temperatures of dawn and dusk provide ideal conditions for targeting these elusive fish, as muskies are more likely to be on the hunt during these times. Additionally, night fishing can also yield successful results, as the water cools down further, encouraging muskies to venture closer to the surface. This combination of seasonal timing and strategic fishing hours offers anglers the best chance to encounter and catch these formidable predators.
Essential Techniques for Targeting Musky
- The Figure-8 Retrieve: This technique is essential when a musky follows your fly close to the boat. Drawing a figure-8 shape in the water keeps the fly moving and can trigger a late strike.
Erratic Retrieves: When using large streamer flies, keep your retrieve varied and erratic to imitate the unpredictable movement of wounded prey. Muskies are ambush predators and will react to erratic movements - Fly Line and Leaders: Use a 10 to 12-weight rod with sinking or intermediate fly lines that can handle bulky flies and reach deeper water. A strong bite tippet is crucial to withstand musky teeth, often a 40-pound fluorocarbon leader
Flies and Lures for Musky
- Bucktails and In-Line Spinners: These classic musky lures work well in warmer water, covering large areas quickly
- Topwater Lures: When water temperatures rise, topwater flies like large poppers can entice explosive strikes from muskies
- Glide Baits: These jointed flies create a wide, side-to-side action that triggers predatory strikes from musky
Conservation and Handling Practices
Muskies, especially tiger muskies, are catch-and-release fish in many Colorado waters, with strict size limits in place. Always use a musky net for safe handling, and keep the fish in the water as much as possible to avoid stressing it
