FISHING GUIDE

THE QUICK ANSWER

WHAT IS SKILAK LAKE, ALASKA?

Skilak Lake is a 24,512-acre glacial lake on the Kenai River inside the Kenai National Wildlife Refuge, reached by Skilak Lake Road off the Sterling Highway. It holds lake trout, rainbow trout and Dolly Varden, has public boat launches at the Upper and Lower Skilak campgrounds, and is known for sudden winds that can raise dangerous waves in minutes.

The Kenai River leaves the lake at its west end and becomes the middle Kenai, the stretch where Marlow's on the Kenai sits in Sterling. For the trout that make this water famous, see Kenai River rainbow trout fishing.

AT A GLANCE

HOW BIG IS SKILAK LAKE?

The U.S. Fish and Wildlife Service lists Skilak Lake at 24,512 surface acres, about 38 square miles. Its bathymetric map gives the maximum depth as unknown, but its depth contours reach 160 meters, about 525 feet.

LOCATION

WHERE IS SKILAK LAKE?

Skilak Lake sits inside the Kenai National Wildlife Refuge on the Kenai Peninsula. The upper Kenai River flows in at its east end and the river leaves at its west end, at about river mile 50, on its way past Sterling and Soldotna to Cook Inlet.

Skilak Lake Road is a loop off the Sterling Highway, with its east entrance at milepost 58 and its west entrance near milepost 75. From the west entrance, USFWS directions put Lower Skilak Campground 5.3 miles in, then 1 mile down the campground road, and Upper Skilak Campground 10.6 miles in, then 2 miles south. ADF&G notes the road is well traveled by anglers and tourists, and that both campgrounds are popular launch sites for fishing the Kenai River inlet and outlet.

The land north of the lake is the refuge's Skilak Wildlife Recreation Area, which has its own rules: it is closed to most hunting and trapping, and from March 15 through September 30 you may not go within 100 yards of the rock islands in the lake used by nesting cormorants and gulls.

SAFETY

IS SKILAK LAKE DANGEROUS?

It can be, mainly because of wind and cold water. ADF&G warns that sudden winds can turn Skilak Lake into a froth of boat-flipping rollers, and Alaska State Parks says high winds can whip Kenai and Skilak lakes into whitecaps in minutes.

• Cold, glacial water: much of Skilak's inflow is glacial meltwater, and State Parks says the water may be below 40 degrees almost year round. Most boating deaths in Alaska involve cold-water immersion.
• Small craft: the USFWS recreation plan advises against paddling rafts or other small craft across the lake because of high winds.
• What to do: check the weather, leave a float plan, wear a life jacket, and stay on shore when it is windy.

THE FISH

WHAT FISH ARE IN SKILAK LAKE?

The most recent USFWS fish survey of Skilak Lake, in 2006, recorded lake trout, rainbow trout and Dolly Varden. Salmon also move through the lake on their way upriver.

• Lake trout: ADF&G says lake trout are wild year-round residents of Skilak and Kenai lakes and are sometimes found at the lake outlets. In summer anglers believe they hold in deeper water and few are caught; in fall and spring they may move to shallower areas and the outlets.
• Rainbow trout: the Kenai River is home to trophy-sized wild rainbow trout, and ADF&G says the best fishing is often in fall, when trout feed on salmon eggs and carcasses. See trophy trout trips and our Kenai River trout fly-fishing guide.
• Dolly Varden: resident and sea-run Dolly Varden overwinter in Kenai and Skilak lakes. ADF&G names the river from Naptowne Rapids up to Skilak Lake, and from the Skilak inlet up to Kenai Lake, as the preferred Dolly Varden water.
• Salmon: fish bound for the upper Kenai and the Russian River, which joins the Kenai above Skilak, pass through the lake. Skilak Lake itself is closed to king salmon fishing.

ACCESS

WHERE ARE THE SKILAK LAKE BOAT LAUNCHES AND CAMPGROUNDS?

Skilak Lake has two public boat launches, both at Kenai National Wildlife Refuge campgrounds on Skilak Lake Road.

UPPER SKILAK CAMPGROUND

At the east end of the lake, with 26 campsites, tables, fire pits, water, toilets and a boat launch. The refuge charges $15 a night for drive-in sites and $10 for walk-in tent sites, and most sites are first come, first served. Boaters who float the upper Kenai through the canyon cross the lake to take out here.

LOWER SKILAK CAMPGROUND

At the west end near the outlet, with 14 campsites, tables, fire pits, water, toilets and a boat launch. It is the put-in for the 12-mile float down the middle Kenai to Bing's Landing State Recreation Site.

DOWNSTREAM

WHAT IS THE KENAI RIVER LIKE BELOW SKILAK LAKE?

Below the lake the Kenai becomes the middle river, which Alaska State Parks defines as Skilak Lake to the Soldotna Bridge. Anglers there target king, coho and sockeye salmon, rainbow trout and Dolly Varden, and the river is busy from June through October.

ADF&G says almost half a million salmon spawn each year in the first four miles below the lake outlet, which draws brown and black bears. The 12-mile float from Lower Skilak to Bing's Landing crosses that water; take out at Bing's, because Naptowne Rapids, rated Class III/IV, is just downstream.

Marlow's on the Kenai is on this middle stretch in Sterling, a family-run lodge with four riverfront cabins, each with a full kitchen, plus private docks and a fish cleaning station. Guided trips are coordinated with local guides; see rainbow trout fishing and trophy trout adventures.

REGULATIONS

WHAT ARE THE FISHING AND BOATING RULES ON SKILAK LAKE?

In the 2026 ADF&G regulations, Skilak Lake falls under the Lower Kenai River general rules, except the half mile around the upper Kenai River inlet, which follows the stricter Middle Kenai River rules.

• Lake: closed to king salmon fishing. Outside the half mile around the inlet, bait and multiple hooks are allowed year-round.
• Limits: rainbow/steelhead trout 1 per day, under 16 inches; Dolly Varden/Arctic char 1 per day, under 16 inches; lake trout 2 per day 20 inches or longer, or 10 per day under 20 inches.
• Outlet: the Kenai River from about 1 mile above the Lower Killey River up to Skilak Lake is closed to all sport fishing May 1 to June 10. From the outlet to about river mile 47, fishing from an anchored boat is prohibited August 1 to December 31.
• Boats: only four-stroke or direct fuel injection motors on Skilak Lake. No motor use on the river from the outlet to river mile 47 from March 15 to June 14. Below the lake, motors are limited to 50 horsepower and boats to 21 feet long, and on Mondays May 1 to July 31 (except Memorial Day) no fishing from a boat with a motor on board between the outlet and the Soldotna bridge.
