This is a list of natural lakes and reservoirs located fully or partially in the U.S. state of Washington . Natural lakes that have been altered with a dam, such as Lake Chelan, are included as lakes, not reservoirs. Swimming, fishing, and/or boating are permitted in some of these lakes, but not all.
Currently included in this table are all natural and enhanced lakes with a surface area of more than 1,000 acres or a volume of more than 25,000 acre feet as well as smaller lakes (down to 100 acres) with a Wikipedia page.
