Henrys Lake stands as one of Idaho’s prized high mountain lakes, captivating anglers with its exceptional trout fishing opportunities. Nestled within the Caribou-Targhee National Forest at an elevation of 6,472 feet, this lake is not just another fishing destination; it’s a dream for those in pursuit of cutthroat, brook, and cut-bow hybrid trout. Surrounded by the breathtaking landscapes of the Continental Divide and located just 15 miles from Yellowstone National Park, Henrys Lake offers more than fishing—it’s one of the most unique things to do in Idaho.
A Rich Ecosystem
Situated in an ancient volcanic crater, Henrys Lake spans nearly 5 miles long and 3.5 miles wide, characterized by its shallow depths and expansive weed beds. This unique geography, coupled with the lake’s nutrient-rich waters, turns it into a thriving ‘food factory’ where trout grow quickly and reach impressive sizes. The surrounding Henrys Lake Mountains and Centennial Mountains not only provide a stunning backdrop but also contribute to the area’s diverse ecosystem, where wildlife such as moose, elk, deer, pronghorn, and even grizzlies roam freely.
The Fish of Henrys Lake
The real stars of Henrys Lake are its fish. With an estimated 1.2 million catchable trout, the lake boasts one of the highest densities of large trout in the West. Anglers can expect to encounter trout ranging from 14 to 18 inches as the norm, with many specimens reaching 18 to 24 inches and weighing between 3 to 6 pounds. The lake’s rich insect biomass supports a healthy trout population, including Yellowstone cutthroat, sterile eastern brook, and hybrid rainbow/cutthroat trout, making every fishing trip a potential story of the one that didn’t get away.
Planning Your Visit
When planning your fishing expedition to Henrys Lake, consider staying at one of the campsites along the shoreline for direct access to the lake’s best fishing spots. The state park offers both developed campgrounds for those seeking comfort and backcountry sites for anglers looking for solitude. Additionally, the park’s cabins provide a cozy retreat after a day spent on the water. Remember to check the weather, as Henrys Lake is known for sudden strong winds that can challenge even the most experienced fishermen.
Activities Beyond Fishing
Aside from fishing, Henrys Lake State Park is a hub for outdoor activities. Hiking and biking trails wind through the area, offering stunning views of the surrounding mountains and an opportunity to encounter the local wildlife. For those interested in the broader ecosystem and the origins of the great Snake River, which begins at Henrys Lake, there are educational trails that provide insight into the lake’s significance to the region’s waterways.
