Baert Lake is a small artificial lake in the unincorporated community of Christmas Valley in the U.S. state of Oregon. Managed by the Christmas Valley Park and Recreation District, the lake is used for fishing, boating, and swimming from spring through autumn and for ice skating in winter if the ice is thick enough.{{cite web|title=Baert Lake|url=http://www.cvparkandrec.org/facilities-properties/baert-lake/|publisher=Christmas Valley Park and Recreation District|year=2018|access-date=April 9, 2019}}
