Hosmer Lake is a natural body of water in the central Cascade Range in the U.S. state of Oregon. Nearly 5000ft above sea level, the lake is part of a volcanic landscape about 20mi west-southwest of Bend along the Cascade Lakes Scenic Byway. In 1962, the United States Board on Geographic Names changed the name from Mud Lake to Hosmer Lake in honor of Paul Hosmer, a naturalist from Bend.Hosmer Lake is about 5mi west of Mount Bachelor in Deschutes National Forest. Nearby lakes include Elk, Sparks, Blow, Doris, Lava, and Little Lava.Encroaching vegetation is gradually turning Hosmer Lake into a marsh. The lake bottom consists of mud and peat, and mosses and aquatic plants restrict the open water. Water lilies and bullrushes are prevalent.RecreationFormerly populated by trash fish, including carp, the lake was treated with rotenone in 1957 and restocked with Atlantic salmon. The landlocked salmon experiment proved successful, and in the 21st century the lake has been called "one of the richest lakes in the Deschutes National Forest". The lake supports populations of "very large" brook trout as well as "deep-bodied" salmon. Only fly-fishing with barbless flies is permitted on Hosmer Lake, and salmon must be released if caught. Boats with electric motors may slowly ply the lake, which is also open to canoes and other non-motorized craft.For Hosmer Lake and beyond, use our Bend itinerary builder website to get the most from your Bend vacation.
Hosmer Lake reviews
Loved, loved, loved this lake. Stayed four days in the Mallard Marsh Campground. We brought our SUPs and paddled every day. The lake sits in the shadow of Mt. Bachelor, South Sister and Broken... more »
Getting crowded, but plenty of space to spread out. Take a picnic and head to north end for the day. more »
Really pretty lake. Don't swim, there are HUGE leeches here.
The best kayaking spot on Cascade Lakes hwy. It starts with a nice sized lake but soon you are meandering through a reed sided water highway with fish and ducks and otters. The lake opens up into a wide lake with amazing views. Be sure to go all the way to the end and up the creek. A double waterfall awaits!
