Darke Lake Provincial Park is a provincial park in British Columbia, Canada located west of Okanagan Lake, southwest of the town of Peachland in that province's Okanagan region. The park is approximately 1470 ha. in size and was established in 1968.[1] Darke Lake, also mapped historically as Fish Lake, is northwest of Summerland and is named after Silas Robert Darke, an early settler in the 1890s.[2][3]
