(From Atlas of Oregon Lakes, Johnson et al. 1985)  Lower Eddeeleo Lake is the largest in a string of remote, back-country lakes that extend northwest of Waldo Lake in the Central Oregon Cascade Mountains. The glacial basin in which these lakes are found is part of the Waldo Lake Recreation Area, a ten square mile region administered by the Willamette National Forest. Given this designation, Lower Eddeeleo and surrounding lakes will continue to be undeveloped and should retain their primitive nature. The lake is named for Ed Clark, Dee Wright, and Leo McMahon, three former U.S. Forest Service employees who used to stock fish in these lakes by packhorse. Upper Eddeeleo Lake does not receive particularly heavy use by fishermen, although it reportedly offers excellent angling for both brook and rainbow trout. The lake is stocked each year and does have some native trout. No improved camp sites are located at the lake, but there are several pleasant, undeveloped ones.

Dense stands of conifer characterize the fairly gentle slopes around Lower Eddeeleo Lake, and a thick forest crowds the entire shoreline. Steady surface inflow from a small, unnamed stream is maintained by Lake Chetlo and Upper Eddeeleo Lake, which are about one-half mile south of Lower Eddeeleo Lake. The outflow stream, also unnamed, is tributary to the North Fork of the Middle Fork of the Willamette River.

Water quality in Lower Eddeeleo Lake is exceptionally good and the lake is classified as ultraoligotrophic. Surface water temperatures remain cool and the lake develops a distinct temperature stratification. Concentrations of major ions are very low as are the concentrations of phosphorus and chlorophyl. Further, water transparency is very high (Secchi disk depth = 40 feet; 12.2 meters) and dissolved oxygen is near saturation at all depths.
