Wallowa Lake was formed by successive ice age glaciation that gouged out the land forming the lake and twin moraines. The East Moraine is considered a near perfect example geologically and thus far has escaped most development, although due to measure 37, this is now at risk. The East and West Fork of the Wallowa River feed the lake with crystal clear snow melt, making the temperature unbearable to most swimmers until mid july. Locals like to joke as they jump in, that the water was snow five minutes ago. Really, after a few weeks of hot weather the water is refreshing and tolerable. The clear, cold water gives the lake a wonderful deep-blue color that beckons most photographers.
The Lake is about 3 3/4 miles long by just over 3/4 mile wide with a depth of 299'. West side access is limited, but a great day-use facility on the north, and State Campground on the south provide boat ramps, picnic tables and restrooms. East side access includes several pull-outs and a spur road. Access from there is good but getting to the lake is steep and rocky and should not be attempted unless your fit.
Kokanee fishing improves, depending on weather, around Mothers Day. Trout is stocked several times through the season and Mackinaw to 38 pounds have been landed.
This panorama was taken from
the east side about 200 yards south of the County Park on the north end of the lake.
Chief Joseph Mountain the large one on the right, and Mt Howard, host of the famous Wallowa Lake Tramway is on the left. Bonneville Mountain is in the center of the image and splits the Wallowa River (shown right )into the East & West Forks. At its base lays the Wallowa Lake Trailhead.
Also at the south end is the resort town of Wallowa Lake.
