How long after the fish arrive can you actually get to them through the ice at Chena Lake? Between late August and early October 2026, the Alaska Department of Fish and Game put more than 32,000 hatchery fish into the 260-acre lake inside Chena Lake Recreation Area, east of North Pole. Weather decides when the ice can hold an angler on foot, and a borough threshold well above that decides when the rental houses open.
A different fish under the ice than last winter
Last fall's main stocking at Chena Lake was coho salmon, put in on September 29 and 30, 2025, at roughly 7.1 to 7.2 inches long. This fall, ADF&G's stocking records show Chinook salmon in that slot, and bigger ones.
| Stocking date, 2026 | Species | Fish released | Average size |
|---|---|---|---|
| Aug 26 | Rainbow trout | 4,758 | 11.8 in., 10.4 oz. |
| Aug 31 | Rainbow trout | 4,246 | 11.7 in., 10.2 oz. |
| Sep 30 | Chinook salmon | 9,942 | 9.1 to 9.3 in. |
| Oct 5 | Chinook salmon | 10,543 | 9.3 in., 5.0 oz. |
| Oct 6 | Chinook salmon | 3,216 | 8.8 in., 4.3 oz. |
That adds up to 23,701 Chinook and about 9,000 rainbow trout in a little over five weeks. The Chinook came in about two inches longer than last fall's coho. The fall rainbows are also larger than the ones stocked this spring: the late-May and mid-June 2026 rainbows averaged about 10 inches and roughly 6 ounces, while the August fish averaged close to 12 inches and over 10 ounces.
Every lot in the table is listed as triploid, meaning sterile. Those fish are there to be caught and won't spawn in the lake. They also aren't the only fish in Chena Lake. ADF&G's Tanana River Drainage Stocked Lakes guide lists Arctic char, Arctic grayling, landlocked salmon and rainbow trout for the lake. In late May, the department also stocked 38,113 coho fingerlings at 2.7 inches each. ADF&G's public Alaska Lake Database shows when each lake was stocked, how many fish went in, and what kind.
The lake is full of fish now. Whether you can reach them depends on the ice.
Four inches for you, twelve for a borough hut
ADF&G's November 2025 ice-fishing release gives these working minimums:
- 4 inches to support a person
- 6 inches for a snowmachine
- 8 to 12 inches for cars and small trucks
- 12 to 15 inches for larger pickups
The same release says no ice is 100 percent safe. It tells anglers to drill test holes starting at shore and working outward, and to stay away from off-colored snow or ice and from beaver and muskrat dens early in the season.
The Fairbanks North Star Borough uses a different number. Parks and Recreation rents six ice houses, four at Chena Lake and two at Tanana Lakes Recreation Area in Fairbanks, and Chena Lake rentals don't start until the ice is 12 inches thick. That's three times what ADF&G gives for one person on foot, and the same thickness the department lists as the top of the car-and-small-truck range.
Last season shows how long that gap can last. On December 5, 2025, the borough posted that Chena Lake ice measured 9.5 inches. By ADF&G's guidance, that ice was already more than twice as thick as a walking angler needs, and the rental houses were still closed. The same notice said Tanana Lakes hadn't been stocked that fall, so the borough wouldn't rent there for the season. That left Chena Lake as the only place the borough's houses operated.
This fall, Chena Lake was restocked, and the houses run under the same seasonal limits as always: available in winter once the ice forms, with March 31 as the last rental date each year. Openings and reservations show up on the borough's Ice House Rentals calendar, and the FNSB Parks and Recreation page posts ice updates as the borough measures.
So the early weeks belong to anglers who bring their own auger and some kind of shelter.
Gear you can borrow while the ice firms up
If you'd like to try a lake full of new fish without buying a rod first, ADF&G's Fairbanks and Delta offices loan out fishing rods. The loaner program requires a current sport fishing license. The rods are free, and you bring your own tackle. Details are on the ADF&G Rod Loaner Program page.
ADF&G's September 2026 Interior report suggested small pieces of shrimp or salmon eggs, or small flashy spoons and spinners, for stocked lakes. That advice was written for open-water season.
The Tanana Valley Fisheries Center, inside the Ruth Burnett Sport Fish Hatchery at 1150 Wilbur Street in Fairbanks, is open to the public Monday through Friday from 10 a.m. to 4 p.m. Visitors can stop in and see what's growing in the hatchery.
The trails that start where the ice fishing does
The ice is only part of the park in winter. The borough lists ski trails, fat biking, ice fishing and aurora viewing as Chena Lake Recreation Area's winter activities, and it manages the park together with the Army Corps of Engineers. If one person in the car is fishing and another isn't, the trails are the other option.
The Alaska Skijoring and Pulk Association describes about 12 miles of groomed mushing and ski trails there, with loops of 1, 3.8, 5.1, 6.8, 9.5 and 12.5 miles. To get there, follow the signs from the Richardson Highway in North Pole, drive about 3.5 miles into the park, turn left at the Lake Park sign, and follow the signs to Mike Agbaba Trailhead. The association points out that the River Park trails are for skiers only, so anyone out with dogs should keep to the Lake Park side. The borough's Chena Lake winter pamphlet maps the trails and locations.
The association also asks trail users to donate toward grooming where they can, since someone spends the time and money to groom them.
The dates that bracket the season
The calendar comes down to a few numbers. The fish went in on August 26 and 31, September 30, and October 5 and 6. Ice can hold a person on foot at 4 inches, and the borough houses open at 12. Borough rentals end March 31. Between 4 and 12 inches, anglers who bring their own auger can fish while the borough houses are still closed.
I've served Interior Alaska since 1994, and Chena Lake is part of what winter looks like on this side of the Richardson. If you're out drilling holes this season and want to talk about North Pole winters, or a neighbor wants a local's read on the area, Ginger Orem is glad to hear from you. Let's Connect.
