is a freshwater lake
located in the Okanagan Valley
of British Columbia
. The lake has the towns Okanagan Falls
to the north, and Oliver
to the south. The lake stage is controlled by McIntyre Dam. Vasuex Creek (and the associated alluvial fan
) are to the south, near McIntyre Bluff; however, it does not flow into Vaseux Lake.
The name "fr:vaseux" is French, meaning muddy or murky, which is descriptive of the lake's silty water. The lake was likely named by French Canadian fur traders.
The lake was misspelled as "Vasuix Lake" on Joseph Trutch's maps from 1866 and 1871. For many years the name was later misspelled "Vaseaux Lake"; in 1945 the Geographic Board of BC corrected the official name to its present form.
