Waptus Lake is an alpine freshwater lake located on the southern stretch of the Okanogan National Forest in Kittitas County, Washington. Because of its proximity to Cooper Lake and the Pacific Crest Trail, Waptus Lake is a popular area for hiking, camping and fishing. Waptus Lake is surrounded by trails that lead to other Alpine lakes in the vicinity, including the Pete Lake and Spectacle Lake at the base of Chikamin Peak.
Ecology
Waptus Lake is one of the largest lakes in the Alpine Lakes Wilderness, located in a prominent valley. The lake stretches from northwest to southeast, approximately 1 mile in length and 0.2 miles wide. Waptus River is one of the tributaries of the Cle Elum River. While mining in the area surrounding Cooper Lake and damming of the Cle Elum River impacted the quality of the salmon habitat, salmon spawning has been prominent on Cle Elum River since the late 2000s.
History
Discovery of a Clovis point projectile along the bottom of Cle Elum Reservoir in 1984, south of Waptus Lake, leads to suggestions that the region may have been a site of the residence of Indigenous peoples of the Northwest Plateau with Clovis culture, perhaps of the Wenatchi People, one of the Confederated Tribes of the Colville Reservation and within the ceded lands of the Yakama Nation. Archaeological surveying in the area shows no additional evidence from materials or engineering to confirm the discovery. Water levels, however, have not receded enough since 1984 to expose the terrace where the point was discovered. In the vicinity of the Salmon La Sac region lie prehistoric and early historic Native American sites including artifact scatter, petroglyphs, resource procurement areas, and seasonal salmon camps indicating that these may be associated with the Kittitas or other Bands and Tribes of the Yakama Nation.

Waptus Lake is located in a hemiboreal climate, part of the marine west coast climate zone of western North America.The average temperature is 3° C. The warmest month is August, with an average temperature of 19° C, and the coldest month is January, at an average of −8° C. The average rainfall is 1687 millimeters per year.

Access
Bordering the Pacific Crest Trail, hiking to Waptus Lake is a popular activity. It is approximately 8 miles from the trailhead at Salmon La Sac Trailhead. The trail has a gentle grade for most of its length, with occasional steep hills. The follows a valley floor with old-growth forest, frequently crossing small snowmelt creeks. Mountain bikes are prohibited beyond this point of the wilderness boundary. The trail intersects Trail Creek Trail 1322 and then Waptus Pass Trail 1329 which lead to the lake over a bridge that was never replaced after a flooding of Waptus River. The trail continues shortly upstream as Waptus Horse Ford Trail 1329.1 and reaches the Pacific Crest Trail 2000.
