An inventory of lakes and reservoirs of Oregon is essential for a complete evaluation of the total surface-water supply of the State and to provide a basis for answering questions about Oregon's lakes. Much of the information on lakes and reservoirs previously collected by Federal and State agencies has never been published. Those data were compiled and used as a basis for collecting additional information. This report provides information for use by city, county, and State planning groups as a basis for designing more advanced interpretative studies. The information also will be useful to sportsmen, tourists, and others interested in preserving the recreational value of Oregon's lakes.
Because of the large number of lakes and reservoirs in Oregon, a single report covering the State would be bulky. Therefore, the lake information is being issued in several volumes on a county or multicounty basis. Volume 1, released in 1973, covered Clatsop, Columbia, and Tillamook Counties; volume 2 (1974) included Benton, Lincoln, and Polk Counties; volume 3 (1975) included Hood River, Multnomah, Washing ton, and Yamhill Counties; and volume 4 (1976) included Clackamas County. Marion County was selected for volume 5. (See figure 1.)
The southeast part of Marion County lies in a national wilderness area. Wilderness areas are protected under the National Wilderness Preservation System that directs management "for the use and enjoyment of the American people in such a manner as will leave them unimpaired for future use and enjoyment as wilderness." Regulations for wilderness use and entry permits may be obtained at U.S. Forest Service offices.
In addition to office compilation of existing data, each lake was visited. Most visits were made in summer or early fall when lakes were most accessible and when water temperature and biological activitiy were near maximum.
