What Are Cutthroat Trout?

Cutthroat trout belong to the Oncorhynchus genus within the salmon family Salmonidae, making them close relatives of rainbow trout and Pacific salmon. These native North American fish evolved into distinct subspecies through geographic isolation over millions of years, creating the remarkable diversity we see today.

Physical Characteristics and Identification

The most distinctive feature of cutthroat trout remains the red, orange, or yellow slash marks on the underside of their lower jaw, from which they derive their common name. These coloration patterns vary significantly between subspecies and individuals.

Body coloration ranges from silvery-blue in sea-run coastal varieties to golden-bronze in mountain lake residents. Most cutthroat trout display black spots concentrated toward the tail section, though spot patterns and density differ among subspecies. The upper jaw extends past the back edge of the eye, distinguishing them from rainbow trout.

Size varies dramatically depending on subspecies and habitat. Stream-dwelling cutthroat typically measure 6-16 inches and weigh 0.5-2 pounds, while lake-dwelling varieties can exceed 20 inches and 5 pounds. The massive Lahontan cutthroat of Pyramid Lake can reach over 40 pounds.

Native Range and Distribution

Cutthroat trout originally inhabited waters from Alaska's coastal streams south to northern California, extending inland through the Rocky Mountains to Colorado and New Mexico. Their historic range covered approximately 58 million acres across western North America.

Today, habitat loss and competition from introduced species have reduced their range significantly. Pure-strain native populations now occupy roughly 25% of their original habitat, making conservation efforts critical for maintaining genetic diversity.

Different Types of Cutthroat Trout

Understanding the different types of cutthroat trout enhances fishing success and appreciation for these remarkable fish. Scientists recognize 14 major subspecies within four evolutionary groups, each adapted to specific environments and displaying unique characteristics.

Coastal Cutthroat Group

Coastal cutthroat trout (Oncorhynchus clarkii clarkii) represent the most widespread subspecies, ranging from northern California to Alaska. These adaptable fish include both resident freshwater forms and sea-run anadromous varieties.

Sea-run coastal cutthroat spend summers feeding in saltwater before returning to freshwater streams for spawning. They display silver coloration with aquamarine backs, earning them the nickname "blue-backs." Resident forms exhibit more typical golden-bronze coloration with heavier spotting.

Rocky Mountain Group

The Rocky Mountain group includes several important subspecies found throughout the interior West:

Yellowstone cutthroat trout (O. c. bouvieri) inhabit the Yellowstone River drainage and surrounding waters. These golden fish display large black spots concentrated toward the tail and provide excellent fly fishing opportunities in pristine wilderness settings.

Westslope cutthroat trout (O. c. lewisi) represent Montana's state fish, native to northern Idaho, western Montana, and southern Alberta. They prefer cool, clear streams and lakes with excellent water quality.

Colorado River cutthroat trout (O. c. pleuriticus) occupy high-elevation waters throughout the Colorado River basin. These hardy fish survive in harsh alpine environments where few other species thrive.

Great Basin Group

Lahontan cutthroat trout (O. c. henshawi) grow to massive sizes in Nevada's alkaline desert lakes, particularly famous Pyramid Lake. These silver giants can exceed 20 pounds and provide trophy fishing opportunities.

Bonneville cutthroat trout (O. c. utah) represent Utah's state fish, adapted to the ancient Lake Bonneville basin. They display heavy spotting across their entire bodies and excellent fighting ability.

Rio Grande Group

Rio Grande cutthroat trout (O. c. virginalis) inhabit high-elevation streams throughout Colorado and New Mexico. These colorful fish display vibrant spawning colors and prefer cold, well-oxygenated waters.

Greenback cutthroat trout (O. c. stomias) serve as Colorado's state fish despite being nearly extinct. Aggressive recovery efforts have restored populations to select waters within their native South Platte drainage.

When Do Cutthroat Trout Spawn?

When do cutthroat trout spawn depends primarily on subspecies, elevation, and local water temperatures. Understanding spawning timing helps anglers plan trips and practice ethical fishing during vulnerable reproductive periods.

Spawning Season Overview

Most cutthroat trout spawn during spring when water temperatures reach 43-46°F (6-8°C). Lower elevation populations begin spawning as early as February, while high-mountain varieties may not spawn until July.

Coastal cutthroat trout typically spawn between February and May in tributary streams. Sea-run varieties return from saltwater during fall and winter, holding in estuaries before ascending spawning streams.

Rocky Mountain subspecies generally spawn from April through June, depending on elevation and snowmelt patterns. High-altitude populations face shorter growing seasons and may spawn later when ice-free conditions develop.

Spawning Behavior and Habitat

Female cutthroat trout select spawning sites in shallow gravel areas with good water circulation. They excavate redds (nests) by turning sideways and beating their tails against the streambed, creating depressions 12-18 inches across.

Depending on body size, females deposit 200-4,400 eggs in the redd. Males fertilize eggs with milt before females cover them with gravel for protection. Eggs develop for 6-7 weeks before hatching into alevins that remain in gravel for an additional 2-3 weeks.

Conservation During Spawning

Ethical anglers avoid fishing over active spawning areas and handle any incidentally caught spawning fish with extreme care. Many waters close during spawning season or implement special regulations protecting reproductive populations.

Look for redds in shallow gravel areas and avoid wading through these critical habitat areas. Spawning cutthroat display bright breeding colors and aggressive territorial behavior, making them easy to identify and avoid.

Best Cutthroat Trout Fishing Locations and Techniques

Best cutthroat trout fishing occurs throughout their native range, with some locations offering world-class opportunities. Success depends on understanding habitat preferences, seasonal movements, and effective presentation techniques.

Prime Fishing Locations

Western Mountain Streams provide classic cutthroat fishing in pristine wilderness settings. Small headwater streams often hold native populations above migration barriers, offering excellent dry fly fishing during summer months.

Alpine Lakes throughout the Rocky Mountains and Sierra Nevada hold beautiful cutthroat populations. These high-elevation waters require hiking access but reward anglers with stunning scenery and willing fish.

Coastal Rivers from California to Alaska support both resident and sea-run cutthroat populations. Tidewater areas provide exciting opportunities for larger sea-run fish during migration periods.

Seasonal Fishing Patterns

Spring fishing coincides with spawning activity and increased feeding as water temperatures warm. Target deeper pools and slower water where fish concentrate before spawning.

Summer fishing offers the most consistent action, particularly in mountain waters. Cutthroat readily take dry flies during prolific insect hatches, making this prime time for fly anglers.

Fall fishing can be exceptional as cutthroat feed aggressively before winter. Sea-run varieties return to coastal streams during this period, providing opportunities for larger fish.

Winter fishing remains possible in ice-free waters, though fish become less active. Focus on deeper pools and slower presentations during cold weather periods.

Effective Fishing Techniques

Fly fishing remains the preferred method for most cutthroat subspecies. These fish readily rise to dry flies and respond well to nymph presentations in deeper water.

Match local insect hatches when possible, though cutthroat rarely prove overly selective. General attractor patterns like Adams, Royal Wulff, and Elk Hair Caddis produce consistent results.

Spin fishing works effectively with small spinners and spoons. Popular choices include Mepps spinners, Panther Martins, and small Kastmaster spoons in gold and silver finishes.

Similar to techniques used for different types of fishing, adapt your approach based on water conditions and target subspecies.

Cutthroat Trout Fishing Guide: Equipment and Setup

A comprehensive cutthroat trout fishing guide begins with proper equipment selection. Cutthroat trout don't require specialized gear, making them accessible to anglers with basic trout fishing setups.

Rod and Reel Selection

Fly fishing setups should feature 4-6 weight rods measuring 8-9 feet for versatility. Shorter rods work well in brushy mountain streams, while longer rods help with line control on larger waters.

Choose reels with smooth drag systems, though most cutthroat fights don't require sophisticated braking power. Focus on reliability over complex features for mountain fishing applications.

Spinning equipment should emphasize light action for optimal presentation and fish enjoyment. Medium-light rods measuring 6-7 feet provide excellent sensitivity for detecting subtle strikes.

Spinning reels in the 2000-3000 size range balance well with appropriate rod weights while providing adequate line capacity for typical cutthroat fishing situations.

Line and Leader Recommendations

Fly fishing lines should match rod weight ratings for proper casting performance. Floating lines work for most situations, though sink-tip lines help in deeper lake fishing.

Leaders should measure 7.5-9 feet in length, tapering to 4x-6x tippet depending on water clarity and fish size. Fluorocarbon tippets provide stealth advantages in clear mountain waters.

Spinning setups perform well with 4-8 pound monofilament or fluorocarbon line. Lighter lines cast small lures more effectively and appear less visible to wary fish.

Consider similar equipment principles used in fishing for other trout species when selecting tackle for cutthroat fishing.

Essential Tackle and Accessories

Fly boxes should contain a variety of dry flies, nymphs, and streamers in sizes 10-16. Include local favorites along with proven general patterns that work across different waters.

Tackle boxes for spin fishing should feature small spinners, spoons, and jigs in various colors and weights. Pack extra snaps and swivels for quick lure changes.

Accessories include hemostats, net, sunglasses, and quality sunscreen for high-altitude fishing. A comfortable day pack allows access to remote fishing locations.

Don't forget proper licensing requirements, which vary by state. Check our guide on fishing license costs for current pricing information.

Fly Fishing Coastal Cutthroat Trout

Fly fishing coastal cutthroat trout provides some of the most exciting angling opportunities on the Pacific Coast. These aggressive predators readily take flies in both freshwater streams and saltwater environments.

Saltwater Fly Fishing Techniques

Beach fishing for sea-run cutthroat requires understanding tidal movements and food sources. Focus efforts around creek mouths, points, and areas with visible baitfish activity.

Use 5-6 weight rods with floating or intermediate sink lines. Cast small streamers that imitate herring, candlefish, or sculpins along shoreline structure and drop-offs.

Morning and evening provide the best action as cutthroat move into shallow water to feed. Overcast days extend productive fishing periods by reducing light penetration.

Freshwater Coastal Fishing

Tidewater fishing in coastal rivers combines saltwater and freshwater techniques. Target areas where fresh and salt water mix, creating feeding opportunities.

Sea-run cutthroat often hold in deeper pools waiting for optimal spawning conditions. Present streamers and weighted nymphs in likely holding areas.

Resident coastal cutthroat in headwater streams respond well to traditional dry fly techniques. Small mountain streams require stealthy approaches and accurate casting.

Streamer patterns should imitate local baitfish species. Clouser Minnows, Woolly Buggers, and simple bucktail patterns in white, olive, and gray prove effective.

Nymph patterns include Prince Nymphs, Pheasant Tails, and Hare's Ear patterns in sizes 12-16. Add split shot or weighted flies to reach feeding depths.

Dry fly patterns work well during insect hatches. Elk Hair Caddis, Adams, and Royal Wulff patterns cover most situations encountered on coastal streams.

Best Lures for Cutthroat Trout

Selecting the best lures for cutthroat trout requires understanding their feeding preferences and habitat characteristics. These opportunistic predators respond to various artificial presentations when properly matched to conditions.

Small Spinning Lures

Inline spinners rank among the most effective cutthroat lures. Mepps, Panther Martin, and Blue Fox spinners in sizes 0-2 produce consistent results across various subspecies.

Gold and silver blades work well in most conditions, though copper and black patterns excel in darker waters. Add bright accent colors like red or chartreuse for increased attraction.

Spoons provide excellent action and casting distance for cutthroat fishing. Small Kastmasters, Little Cleos, and Krocodiles in 1/8-1/4 ounce weights cover most situations.

Specialized Cutthroat Lures

Rooster Tails combine spinner action with soft plastic tails, creating irresistible vibrations. Choose natural colors like brown and white for clear water conditions.

Small jigs tipped with soft plastics or live bait work exceptionally well in deeper water. Use 1/16-1/8 ounce jig heads with grub tails or small tube baits.

Crankbaits in minnow patterns can trigger strikes from larger cutthroat trout in lake environments. Choose shallow-running models for most cutthroat habitat.

Lure Selection by Subspecies

Coastal cutthroat respond well to lures imitating small baitfish. Silver and blue combinations match common prey species in saltwater environments.

Rocky Mountain subspecies prefer lures that imitate aquatic insects and small fish. Earthtone colors blend naturally with typical mountain stream environments.

Match your lure selection to local prey species and water conditions. Consider the same principles used when selecting hooks for different fish species to optimize presentation.

Common Mistakes When Fishing for Cutthroat Trout

Avoiding common mistakes dramatically improves cutthroat fishing success rates. These errors often result from misunderstanding cutthroat behavior or using inappropriate techniques.

Presentation Errors

Using oversized lures represents the most frequent mistake. Cutthroat trout, especially stream dwellers, prefer smaller presentations that match natural prey sizes.

Poor timing leads to frustrating fishing trips. Avoid fishing during bright midday conditions when cutthroat seek cover in deeper water or undercut banks.

Inadequate stealth spooks wary cutthroat in clear mountain waters. Approach fishing spots carefully and avoid casting shadows over target areas.

Tackle Selection Mistakes

Heavy tackle reduces bite detection and fighting enjoyment. Light tackle provides better lure action and more exciting battles with cutthroat trout.

Wrong line choice affects lure presentation and visibility. Match line weight to conditions and use fluorocarbon leaders in clear water situations.

Ignoring local patterns limits success rates. Research successful flies and lures for specific waters before traveling to new destinations.

Habitat Misunderstanding

Fishing wrong water wastes valuable time. Focus efforts on likely cutthroat habitat including undercuts, deep pools, and tributary mouths.

Seasonal errors occur when anglers fish spawning areas or use inappropriate techniques for current conditions. Adjust tactics based on water temperature and season.

Learn from mistakes and adapt techniques based on results. Similar principles apply whether targeting cutthroat trout or fishing different lakes across the country.

Pro Tips for Cutthroat Success

Professional guides and experienced cutthroat anglers employ specific strategies that consistently produce results. These proven techniques work across different subspecies and water types.

Advanced Fly Fishing Strategies

Match local hatches whenever possible, but don't become overly focused on exact imitation. Cutthroat trout rarely prove as selective as other trout species.

Use attractor patterns during periods of low insect activity. Royal Wulff, Stimulator, and Renegade patterns often trigger strikes when nothing else works.

Vary retrieve speeds when fishing streamers and wet flies. Cutthroat respond to different presentations depending on water temperature and feeding mood.

Spin Fishing Excellence

Work likely cover thoroughly before moving to new locations. Cast tight to logs, undercut banks, and boulder shadows where cutthroat ambush prey.

Maintain lure contact throughout the retrieve to detect subtle strikes. Cutthroat often take lures gently, requiring constant attention to line movement.

Change lures frequently if not producing strikes. Cutthroat preferences can vary based on light conditions, water temperature, and feeding patterns.

Location and Timing Secrets

Fish during weather changes when cutthroat become more active. Approaching storms and dropping barometric pressure trigger feeding responses.

Target transition areas where different water types meet. Creek mouths, tributary confluences, and thermal layers concentrate feeding cutthroat.

Plan around moon phases for enhanced night fishing opportunities. Full moons provide enough light for safe fishing while maintaining fish activity levels.

Apply these professional techniques whether fishing from shore or using different boat types for fishing access to remote locations.
