Muskellunge

Overview and identification

The muskellunge (Esox masquinongy) is Kentucky's largest pike. KDFWR describes it as shaped like the grass pickerel but far bigger, dark green or brown on the back and silvery on the sides with dark, broken vertical bars that fade in adults, and fins that run olive to reddish-brown, often with large dark spots. Northern fish are reported to reach 72 inches and 70 pounds; in Kentucky, KDFWR says, fish over 50 inches (40 pounds) are uncommon. The fish native to Kentucky's streams is the Ohio River form, which KDFWR's stream research named Esox masquinongy ohioensis.

The state record is 47 pounds, caught by Sarah Terry of Mt. Sterling from Cave Run Lake on 2 November 2008, per KDFWR's record table. KDFWR's 2019 fall-muskie article gives the length, 54 inches, and the lure, a silver Double Cowgirl in-line spinner. The record table lists weight only.

The fish you might confuse it with, from the official marks:

• Cheek and gill cover. KDFWR's Fishing and Boating Guide gives two marks for a muskellunge: a duck-like bill with sharp teeth, and no scales on the lower half of the cheek and gill flap. The Ohio Division of Wildlife's Sport Fish of Ohio identification booklet, read 5 November 2026, states the contrast: on a muskellunge "scales on cheeks are found only on the upper half and gill cover," while on a northern pike the "lower half of the gill cover is scaleless with a fully scaled cheek." Its Muskellunge Fishing in Ohio publication puts it more simply: the muskellunge has "cheeks that are half-scaled; the others have fully scaled cheeks," the others being northern pike and the pickerels.
• Grass pickerel. The common small relative. KDFWR separates the two by the vertical black stripe below the eye, which the grass pickerel has and the muskellunge lacks. A grass pickerel tops out around 15 inches.
• Northern pike and chain pickerel. KDFWR's fish booklet calls both rare in Kentucky; the pike is introduced. Status pending on the spot pattern: the rule that a muskellunge carries dark marks on a light background and a pike light spots on dark came from an Ohio DNR species page that returned "not found" on 5 November 2026, and none of the agency documents we read on 5 November 2026 states it. The Ohio booklet gives the cheek scales and a second count instead: a muskellunge has "up to 11 sensory pores on the underside of each side of the lower jaw," a northern pike "usually fewer than seven."
• Tiger muskie. The muskellunge-pike hybrid. KDFWR keeps it as a separate state-record category (19.56 pounds, a private lake in Clark County, 2007). We found no agency field description for it. See the rules section: the regulation does not say how it is treated.

The rules

Statewide, under 301 KAR 1:201 Section 2: muskellunge daily limit one, size limit 30 inches, possession limit twice the daily limit, so two. The season is open year-round. Four lakes raise the minimum, each in the same words, "Muskellunge size limit, forty (40) inches":

The 2026–27 Fishing and Boating Guide, updated September 2026, prints the same four lake rules, and KDFWR's waterbody records for all four read "Must be 40 inches or over. Statewide creel limits apply." The lake boundaries matter because the 40-inch rule stops at them: Cave Run Lake runs up Scott's Creek to the KY 801 culvert, Beaver Creek to the KY 1274 culvert, North Fork to the Craney Creek confluence, the Licking River to the KY 772 bridge, and Ramey Creek to include the pool north of KY 801. Green River Lake runs up the Green River to the Snake Creek ramp, Robinson Creek to the KY 76 bridge and Casey Creek to the Arnolds Landing ramp. Below those lines, and below every dam, the statewide 30-inch rule applies.

Three more rules that reach a muskie angler:

• Measuring. The Guide: "Measure all fish from the tip of the lower jaw (closed) to the tip of the tail with fish laid flat on rule with tail lobes squeezed together." A short fish goes back immediately, "in the best possible physical condition."
• Gigging and snagging. Any sport fish taken by gigging or snagging must be returned to the water regardless of condition, and at Cave Run gigging and snagging are prohibited in the lake and tributaries up to the first riffle.
• Trophy Fish award. KDFWR's Master Angler program lists muskellunge at a 40-inch minimum, with a side-view photograph, submitted within 60 days.

How the 40 came about. KDFWR's Fish and Wildlife Commission agenda for September 2021 proposed to "Increase the minimum size limit for muskellunge from 36 in. to 40 in." at Cave Run, Dewey and Green River lakes, and a KDFWR release dated 29 December 2022 announced the change. Neither document gives a reason, and the regulatory filing that might was not readable this week. Buckhorn's history is different: KDFWR's 2013 survey report refers to its limit moving from 40 to 36 inches in 2010; the current regulation says 40, and we did not establish when it went back. Older KDFWR pages, including the 2019 fall-muskie article, still say 36. They are out of date. The regulation text, amended most recently effective 3 September 2026, says 40.

What the regulation does not say. 301 KAR 1:060 makes "Musky", "Northern Pike", "Chain Pickerel" and "Hybrids of any of the above" sport fish that may be taken only by angling. Nothing in 301 KAR 1:201 says whether a tiger muskie counts as a muskellunge for the 30- or 40-inch minimum or the one-fish limit, and it sets no northern pike limit at all. Chain pickerel has its own: five a day, no size limit. Status pending: if you intend to keep a tiger muskie or a pike, ask KDFWR first.

Where they are in Kentucky

KDFWR names the native range as the Green, Kentucky, Licking and Little Sandy river drainages, and Kinniconick and Tygarts creeks. Native fish live in the pools of medium to large rivers, "often near fallen logs with accumulated debris." KDFWR lists four lakes as stocked annually: Cave Run, Green River, Dewey and Buckhorn (2024 was the exception; see Cave Run below). It also says "several stream populations are also maintained through supplemental stockings due to poor reproductive success in the wild."

KDFWR's 2026 Fishing Forecast, which it says is based on 2025 population surveys, carries a muskellunge line for eight waters. Its star ratings, out of five:

The streams KDFWR stocked in 2023, the last year with a full stream program in its hatchery tables, run longer than the forecast list: the Licking River below Cave Run, the Little Sandy, Kinniconick and Tygarts creeks, Red River, Station Camp Creek, Triplett and North Fork Triplett creeks, the Kentucky River and its North and South forks, the Redbird River, Goose and Sexton creeks, the Levisa Fork, the Green and Barren rivers, and Drakes and West Fork Drakes creeks. Most received tens of fingerlings, not thousands; the exception is fry, released by the hundred thousand into the Licking River below Cave Run. Since then the stream program has nearly stopped: the hatchery tables show no stream fingerlings at all in 2024, and 54 in 2025 (37 into Tygarts Creek, 17 into Kinniconick) against a planned 4,500. Paintsville Lake, Carr Creek Lake and Barren River Lake itself appear in no muskie record we read.

Cave Run Lake

Cave Run is the state's muskie lake for a reason KDFWR states plainly in its own stream report: "Previous stockings of muskellunge throughout Kentucky have resulted in some of the state's premier fisheries such as Cave Run Lake and Green River Lake." The Cave Run Lake guide carries the launches, the Forest Service rules and the pool table; this section is the muskie record.

How the fishery was built

The lake flooded the fish's own stream. James Axon, a KDFWR biologist, reported in the North American Journal of Fisheries Management in 1981 that impounding Cave Run in 1973 and 1974 eliminated 63 miles of excellent muskellunge stream habitat, and that the stocked lake replaced it fast: the fishery was developed by late summer 1975, and in 1976 anglers creeled 1,029 muskellunge at about one fish per 48 hours of fishing. He estimated 2,776 fish of 29.5 inches or longer in the lake in 1978.

Stocking, year by year

KDFWR's 1989 Green River Lake bulletin dates Cave Run's annual stocking program to 1974. The fish are reared at the Minor E. Clark Fish Hatchery below the dam, and KDFWR marks each stocked fish with a fin clip or wire tag for its year class. The plan is 2,700 fish of 13 inches a year. What the hatchery tables say actually went in:

Two lean year classes stand out. KDFWR's year-class table records 24 fish stocked from the 2020 spawn, and 2024 delivered 380 against the planned 2,700. In 2024 Green River, Buckhorn and Dewey lakes received none. The reports give the cause only as "unplanned reduced stocking rates" and "production issues." The hatchery also releases fry into the Licking River below the dam: 163,517 in 2025.

What KDFWR's survey found

KDFWR samples Cave Run's muskie each spring by daytime electrofishing and scores the population on catch rates of age-1 fish and of fish over 20, 30, 36 and 40 inches.

• 2024. Sampled 25 and 27–28 March, water 50 to 53 F, lake at 725.4 to 725.8 feet. 62 fish, 10.0 to 46.0 inches, aged one to nine, caught at 3.4 fish per hour across the upper, middle and lower lake. Rating: Poor, "possibly associated with unplanned reduced stocking rates in several recent years." The catch rate of fish 40 inches and over was 0.2 per hour.
• 2023. 85 fish, 11.0 to 47.0 inches. Rating: Poor.
• 2022. 86 fish, 13.0 to 51.0 inches. Rating: Good.
• 2025. Not sampled: "high water and flooding conditions that persisted for most of the spring."

For scale, the same table rated the population Excellent in 2010, 2014 and 2017. Read the recent ratings with the stocking table beside them: the agency itself links the two.

How fast they grow

KDFWR's known-age table, averaging every clipped or tagged fish it aged from 2011 to 2024, gives Cave Run muskie at 14.2 inches at age one, 23.8 at two, 30.7 at three, 33.6 at four, 36.8 at five and 38.0 at seven. Only six fish were aged nine; they averaged 39.9 inches. The 2019 KDFWR article put it as "five to six years for a muskellunge to reach 36 inches."

Reasoning, not measurement: on those averages, a typical Cave Run fish is still short of 40 inches at age nine. The fastest-growing fish get there sooner, and KDFWR's 2022 sample turned up a 51-inch fish, but a 40-inch minimum here protects most fish for most of their lives. That is a reading of KDFWR's table, not a statement KDFWR makes.

Who fishes it, and what they keep

KDFWR's 2024 roving creel survey, March to October, counted 41,092 fishing trips to Cave Run. 19.4 percent of them were muskie trips (16.7 percent without forward-facing sonar, 2.7 percent with it), and 21.9 percent of anglers in the attitude survey named muskie as the species they fish for most. The survey's figures for muskie anglers:

• Harvest. "As has been the case in recent years, no Muskellunge were reported as harvested." Asked what share of the legal muskie they caught in the last three years they kept, 77.3 percent said none.
• Catch rate. Muskie anglers fishing without forward-facing sonar caught 0.02 fish per hour, roughly one fish per 50 hours; those using it caught 0.10, five times the rate.
• Satisfaction. 63.1 percent of muskie anglers were satisfied, 26.9 percent dissatisfied, and of the dissatisfied, 89.5 percent named the number of fish.
• The 40 over the last three years. 54.6 percent said their catch of fish over 40 inches stayed the same, 27.0 percent said it declined, 9.2 percent said it increased.

Where and when, in KDFWR's words

• Spring. The 2026 forecast: trophy fish "can be found primarily in the spawning month of April in the backs of the large coves and Beaver Creek." Its statewide note adds that muskellunge "move in spring to shallow shoreline structure and headwater areas in search of warmer water" at all four lakes.
• Early fall. The same forecast: "the fall months of September and October in association with gentle sloping gravely banks or near channel drop offs." KDFWR's 2019 creel survey report called September the best month for muskie.
• Late fall and winter. KDFWR's 2019 article: "The best fishing, once the lake level has reached winter pool, is on the lower end of the lake by the dam."

The fall drawdown piece works through how the Corps schedule turns those three statements into a calendar. In short, from the Louisville District schedule verified for our Cave Run guide in September: summer pool 730.0 feet holds until 15 September, the lake eases to 729.5 by 14 October, then drops to winter pool at 724.0 by 1 December, and refills from 16 March to 1 May. The Louisville District's own site would not load on 5 October 2026 (it served a certificate for another domain), so the schedule was not re-read today; the Corps' Daily Lake Report, which did load, still lists Cave Run's summer pool at 730.0 and winter pool at 724.0. Read the lake on USGS gauge 03249498, parameter 62614. On 5 October 2026 at 4:05 p.m. it read 729.66.

KDFWR's access records carry winter-pool warnings for Warix Run, Beaver Creek, Blackwater and the Ramey Creek carry-down, and the Forest Service prohibits fishing from any ramp or courtesy dock on the lake; the Cave Run guide has all seventeen launches. Two ramps are camper-only and seasonal. The Forest Service lists Zilpo's season as the third Friday in March to the last Sunday in October, with the ramp closing above 740 feet, and Twin Knobs' as the second Friday in March to the first Sunday in November, with its ramp "unsafe and/or inaccessible" above 733 feet. On 5 October 2026 no Forest Service alert named a Cave Run closure.

One more record worth knowing in the fall. The Corps' temperature and dissolved-oxygen report for the dam station on 2 October 2026 read 24.5 C (76 F) from the surface to 20 feet, and oxygen near 7 mg/l down to 30 feet, then 1.14 mg/l at 35 feet and below 0.4 from 40 feet down. That is one station on one morning, not the whole lake.

Reasoning, not measurement: on that morning, the water below about 35 feet at the dam held little oxygen for fish of any kind, and it stays that way until the lake mixes. KDFWR makes the same point outright about Green River Lake, where its forecast notes summer oxygen "too low to support fish below 17-20 feet."

Below the dam

The Licking River below Cave Run is a muskie water under the statewide 30-inch rule. KDFWR's Licking River page calls it "one of Kentucky's best native muskellunge streams" and says "Those long, deep pools with woody cover hold muskellunge." KDFWR's 2022 tailwater creel found 8.49 percent of trips were for muskellunge, made in May, June and October, with 15 fish caught in May. KDFWR's tailwater waterbody record lists only rainbow trout, so do not read the record as the whole story.

Green River Lake

Green River Lake is 8,210 acres in Taylor and Adair counties, per the forecast; the Green River Lake guide has the launches, the four road corridors and the pool table. KDFWR selected it for muskellunge in 1977, according to its 1989 bulletin evaluating the introduction, and in 2019 called it "rated excellent for the species," with biologists routinely seeing fish over 45 inches.

The record since is thinner. The 2026 forecast: "Legal-size fish (40-inch) and trophy fish (45-inch plus) available, but lower numbers. Fall, late winter, and spring are excellent times to catch trophy fish. Trolling main lake flats is good option summer through fall." KDFWR's late-winter sampling has been knocked out by high water in several recent years, and in 2025 the sample was too small for anything but condition figures. The 2024 creel survey counted 2,169 hours of muskie fishing, up from an all-time low of 710 in 2018, with a legal-size (40-inch) catch rate of 90.4 hours per fish. Muskie anglers caught only 10 percent of the 241 muskie caught on the lake that year.

Stocking: 1,047 fish of 12.2 inches in 2025, none in 2024, 2,700 in 2023. The forecast's summer note matters for where muskie can be: "Summertime (mid-June through mid-October) oxygen levels are too low to support fish below 17-20 feet."

Pool, from the Louisville District schedule verified for our Green River Lake guide in September: summer pool 675.0 feet, 674.5 by 14 October, winter pool 668.0 by 1 December. Gauge: USGS 03305990, parameter 62614.

Dewey Lake

Dewey Lake, Floyd County, is the new one. KDFWR first stocked muskellunge there in 2014, 500 fish of 13 inches, "to establish a fishable population." The 2026 forecast lists it among the year's "New Up-and-Comers": "An up and coming fishery with increasing numbers of fish over 30 inches. Muskellunge are stocked annually. Anglers continue to report catching larger fish each year, some now over 40 inches." It says fish feed on shad at the backs of the larger coves, such as Big Branch, and along shallow road-side banks, and that zebra mussels and hydrilla are present.

KDFWR's own sampling is less sunny so far. It first sampled the population in 2023 and rated it Poor in 2023, 2024 and 2025 on low catch rates; the 2025 sample was four fish, 25.2 to 47.2 inches, the largest 29.2 pounds. KDFWR's 2023 report called that first rating Fair, and its 2025 table lists it as Poor; we print the later table. Stocking: 285 fish of 11.7 inches in October 2025, none in 2024.

Pool: the Huntington District's water-management page gives summer pool 650 feet and winter pool 645, and notes that below 645 the marina and Terry launch ramps are uncovered. It gives no fill or drawdown dates, so those are Status pending.

Buckhorn Lake and tailwater

Buckhorn Lake, 1,230 acres in Leslie and Perry counties per the forecast, gets the most month-by-month muskie advice of any water in the 2026 forecast:

• January to March: "fish will congregate in the lower lake and near the dam in shallow water brush and submerged trees."
• July and August: "Trace Branch and portions of the headwater area (upper Middle Fork of KY River) provides good fishing."
• September: "look for larger fish along edges of weed beds in backs of coves in shallow water."
• Tailwater: "Bank fishing opportunities are good at the tailwater in March and October."

Access, 2026: the forecast says "the lower lake ramp and parking lot at the dam are undergoing renovations and will not be available for use in 2026." Plan the winter lower-lake fishing around that.

The population: "Overall numbers are stable with the majority of fish less than 36 inches. Fish over 40 inches are available and slightly more numerous." KDFWR rated it Fair in 2023 and 2024; the 2024 sample was 18 fish, 13.5 to 40.5 inches. It was not sampled in 2025 because of high water. No fish were stocked in October 2024, "with poor hatchery survival for 2024"; 250 fish of 11.7 inches went in during October 2025, split between the State Park ramp and Trace Branch.

Remember the boundary: the 40-inch minimum is the lake's rule. The tailwater falls under the statewide 30 inches. Pool schedule: Status pending (the Louisville District page was unreachable this week). Gauge: USGS 03280800, parameter 62614.

Rivers and native streams

All of these fall under the statewide 30-inch, one-fish rule.

• The eastern native streams. KDFWR's Tygarts Creek page calls Tygarts, the Little Sandy River and Kinniconick Creek "three legendary native Kentucky muskellunge streams," says past population studies found muskellunge prefer brush and fallen trees on Tygarts "to all other habitats," and recommends floating Tygarts from mid-September through November over July and August. KDFWR stocked 37 fish into Tygarts and 17 into Kinniconick in 2025.
• Licking River. See Below the dam above. KDFWR's 2018 stream survey from the Cave Run dam toward Falmouth caught eight muskellunge, 0.9 per hour of electrofishing.
• Kentucky River. The forecast's 3.5-star line: "Best in spring around creek mouths, and in summer around timber and creek mouths. Stocked annually in upper river. More fish in upper half of river (pools 6-14)." KDFWR's hatchery tables list no Kentucky River stocking in 2024 or 2025.
• Green River below the lake. "Fishing best below riffle area in deeper pools, spring and feeder creek mouths, and around woody debris or other current breaks. Fish regularly come through the dam during discharge periods and are also stocked annually (when available) throughout the river from Greensburg to Rochester." Our Green River Lake tailwater guide covers the access below the dam.
• Barren River. "40-inch plus fish present." The forecast lists the stocking years: 2023, 2019, 2017, 2016 and 2014.
• West Fork Drakes Creek. "Fish stocked at low water fords below the dam." Best in the deeper holes from the dam to the Barren River confluence, year round.

The history is a warning. KDFWR's 1980 study of native stream muskie reported that as of 1974 Kentucky had 14 streams with appreciable populations, and that "considerable musky stream habitat in the state had been destroyed or degraded by the impoundment and/or pollution of musky streams." Cave Run alone flooded 63 miles of it.

The fish through the year

The best Kentucky-specific spawning record is KDFWR's study of native stream fish, published in 1980 from work in 1967 to 1971: "Musky began their initial pre-spawning movements near the end of March. Musky generally spawned during the last half of April or early May when water temperatures were averaging 55°-60° F," in shallow water at the upper or lower ends of low-gradient pools, mostly at age four. By June, spawned-out adults were found as far as 12 miles from where they spawned. The Ohio Division of Wildlife's figures, read 5 November 2026, agree: its Muskellunge Fishing in Ohio publication says "Spawning occurs in April and May when water temperatures reach the low 50s," and its Sport Fish of Ohio booklet says "Usually in April when the water temperature reaches above 50°f." The forecast's "spawning month of April" at Cave Run fits the same window.

Forage, in the agencies' words: the Ohio Division of Wildlife's Sport Fish of Ohio booklet lists the muskellunge's food as "Soft-rayed fish such as suckers and gizzard shad," and its Muskellunge Fishing in Ohio publication adds that "Suckers are usually the most common food in streams; gizzard shad is the predominant forage in lakes"; KDFWR's forecast has Dewey's fish feeding "aggressively on shad," and its Tygarts page names golden redhorse and spotted suckers in the streams. In the fall, KDFWR's 2019 article quoted its biologist: "Bass go through a heavy feeding period in the fall, and muskellunge do the same thing."

Put the four lakes' KDFWR statements in one calendar:

What KDFWR says catches them

This page sticks to what an agency has published. The tackle conversation, rods, line ratings and leaders, lives in the fall drawdown piece.

• Lakes, early fall. KDFWR's 2019 article recommended a 4-inch balsa crankbait in silver and black and a half-ounce dressed in-line spinner, then upsizing as the water cools to rubber and hard-bodied jerkbaits, single- and double-bladed in-line spinners and spinnerbaits.
• Licking River. KDFWR: "A medium-running crankbait designed for bass in chrome, gold, orange, or firetiger colors is an overlooked and deadly presentation," and "A white or chartreuse bass spinnerbait is another excellent choice to fish around the stumps, limbs, and fallen trees."
• Tygarts Creek. Bass-sized crankbaits in gold or chartreuse, matching the redhorse and suckers, and "A large in-line spinner dressed with bucktail."
• West Fork Drakes Creek. Bucktails, swimbaits and jerkbaits, per the forecast.
• Green River Lake. Trolling main-lake flats, summer through fall.
• The state record. A silver Double Cowgirl in-line spinner, Cave Run, November.
• Electronics. At Cave Run in 2024, muskie anglers using forward-facing sonar caught fish at five times the hourly rate of those who did not (0.10 against 0.02).

Handling and release

Almost every muskie caught at Cave Run goes back, by rule or by choice, so how it goes back is most of the fishery. KDFWR's legal definition of a release is "return of the fish, in the best possible condition, immediately after removing the hook, to the water from which it was taken." KDFWR publishes no muskellunge-specific handling guidance that we found. Its general angler handbook says to handle a fish as little as possible, unhook it in the water where you can, and, "In warmer water, moving the fish back and forth with water entering the mouth will help the fish recover more quickly."

Water temperature is the part with new evidence. A 2023 study in the Transactions of the American Fisheries Society, run in experimental ponds in several eastern states, not in Kentucky, found that 30.0 percent of angled muskellunge died, against 11.3 percent of unhandled controls, with mortality rising with water temperature and with time in the net. It recorded no deaths per 100 angler-hours below 25 C (77 F). The authors concluded that catch-and-release mortality poses risks "in the species' southern range and where summer water temperatures exceed 25°C." The study does not name Kentucky; its line is the temperature, and Cave Run's surface read 24.5 C at the dam on 2 October 2026.

What we don't know yet

• Tiger muskie and northern pike limits. The regulation does not say how a tiger muskie is treated against the muskellunge limits, and it sets no pike limit. Status pending; ask KDFWR before keeping either.
• The spot-pattern rule against northern pike. Earlier versions of this page said a muskellunge carries dark marks on a light background and a pike the reverse, citing an Ohio DNR species page that returned "not found" on 5 November 2026. None of the Ohio Division of Wildlife publications or KDFWR documents read on 5 November 2026 states it, so it is Status pending. The cheek scales and the jaw-pore counts above are the marks those documents do give.
• Why the minimum went to 40. The Commission agenda and the 2022 release state the change, not the reason. The regulatory filing might; it returned a server error every time we tried.
• Why 2020 and 2024 stockings collapsed. KDFWR says "production issues" and "unplanned reduced stocking rates." Nothing more specific is published that we found.
• The Louisville District's pages. Its site served the wrong security certificate on 5 October 2026, so the fill and drawdown schedules for Cave Run and Green River Lake rest on our September reads, and Buckhorn's schedule is Status pending. Dewey's fill and drawdown dates are not published on the Huntington District page.
• Recent survey data for the native streams. KDFWR's 1980s and 1990s stream bulletins are scanned and were not read for this page, and we found no 2020s assessment for Kinniconick, Tygarts, the Little Sandy, Red River or Triplett Creek.
• Spots. Nothing here names a hole, a weed edge or a channel swing, and nothing should be read as one. The forecast's coves, banks and drop-offs are as specific as the public record gets.
