Lake trout illustration

Lake trout

Spring and fall in shallow water, deep in summer, and through the ice in winter

Lake trout are slow-growing chars of large, deep, cold lakes, native from Alaska and northern Canada to New England and the Great Lakes, and introduced in many western lakes. Spring and fall bring lakers into 10 to 30 feet of water (Michigan DNR), within reach of casters and shallow trollers; fall is also spawning time over rocky shoals.

Before you go

License

Wyoming requires a valid fishing license for adults. Buy online from the state agency; one-day options exist for visitors.

Regulations

Wyoming fishing license. Park limits for lakes: 6 trout a day or in possession, no more than 3 of them cutthroat and no more than 1 cutthroat over 12 inches (the trout count excludes lake and brook trout); lake trout 6 in possession, no more than 1 over 24 inches. NPS points to Wyoming Game and Fish mercury advisories for cutthroat, brown and lake trout taken from Jackson Lake and the Snake River.

Trailers may stay up to 72 hours at Signal Mountain, Colter Bay and Leeks Marina; Spalding Bay needs a parking permit.

About this water

Natural lake raised by Jackson Lake Dam on the Snake River, Grand Teton National Park, Teton County, Wyoming. Lake level on this page comes from USGS gauge 13010500, Jackson Lake near Moran.

Fishing Jackson Lake: the full guide

A raised natural lake

The National Park Service describes Jackson Lake as the park's largest lake, a natural lake raised by a 39-foot man-made dam. It is the only lake in the park open to motorized boats of any size, and the only one where water skiing is allowed.

Park fishing rules

Fishing follows Wyoming law and needs a Wyoming fishing license, sold in the park at Flagg Ranch, Colter Bay Marina and Signal Mountain Lodge as well as online. Lakes in the park are open to fishing year-round. Two rods may be used with the angler in attendance, each with no more than three hooks, flies or lures, and on lakes only listed dead non-game baitfish may be used as bait.

Low water in fall 2026

Jackson Lake's level depends on snowpack, downstream demand and dam maintenance. The park's conditions page, updated Sept. 30, 2026, listed the Signal Mountain boat ramp open with launching at your own risk on loose cobbles below the ramp edge, and the Colter Bay ramp, Leeks ramp and both marinas closed.

Common questions

Is Jackson Lake closed to fishing in October?

No. The park's current fishing page says lakes in Grand Teton National Park are open to fishing year-round; the seasonal closures it lists apply to streams and parts of the Snake River.

How many lake trout can I keep at Jackson Lake?

Six in possession, with no more than one over 24 inches, under the park's limits.

Which boat ramps are open?

On the park's Sept. 30, 2026 update only Signal Mountain was open, at your own risk; Colter Bay and Leeks ramps were closed by low water.

How this page was made. The daily report is computed by our scoring engine from live readings; nobody types it. The written text was drafted with AI assistance from the official pages listed above, and its facts were checked against those pages by automated verification on October 8, 2026; anything that could not be verified was taken out. Pablo Ruiz Quintero sets every guideline, the data-verification system and the minimum standards a page must meet to be published, reviews page structure and approves what goes live; the responsibility is his, and the AI carries out the work. We work this way because it is how one person can keep every page current with named sources. Errors are published in the verification log; the full policy is in the editorial policy.
