Grand Teton National Park allows boating on all the lakes in Jackson Hole, but motorized boats can only be used on Jackson and Jenny Lakes.
While there is no maximum horsepower limit on Jackson Lake (though there is a noise restriction), Jenny Lake is restricted to 10 horsepower.
Only non-motorized boats are permitted on Bearpaw, Bradley, Emma Matilda, Leigh, Phelps, String, Taggart and Two Ocean Lakes.
There are four designated boat launches located on Jackson Lake and one on Jenny Lake.
Additionally, sailboats, windsurfers and water skiing are only allowed on Jackson Lake and no jet skis are permitted on any of the park waterways.
All boats are required to comply with various safety regulations including personal flotation devices for each passenger.
Only non-motorized watercraft are permitted on the Snake River.
All other waterways in the park are off limits to boating, and this includes all alpine lakes and tributary streams of the Snake River.

In 2010, Grand Teton National Park started requiring all boats to display an Aquatic Invasive Species decal issued by the Wyoming Game and Fish Department or a Yellowstone National Park boat permit.
In an effort to keep the park waterways free of various invasive species such as the Zebra mussel and whirling disease, boaters are expected to abide by certain regulations including displaying a self-certification of compliance on the dashboard of any vehicle attached to an empty boat trailer.

Grand Teton National Park fisheries are managed by the Wyoming Fish and Game Department and a Wyoming state fishing license is required to fish all waterways in Grand Teton National Park.
The creel limit for trout is restricted to six per day, including no more than three cutthroat trout with none longer than 12 in (30 cm), while the maximum length of other trout species may not exceed 20 in (51 cm), except those taken from Jackson Lake, where the maximum allowable length is 24 in (61 cm).
There are also restrictions as to the seasonal accessibility to certain areas as well as the types of bait and fishing tackle permitted.
