The Sweltzer River is a river in British Columbia, Canada, that drains the waters of Cultus Lake into the Chilliwack River. It is about long, and much of it runs through Soowahlie Indian Reserve No. 14, which is under the administration of the Soowahlie Indian Band. The name Sweltzer River was applied on an 1895 map to Liumchen Creek, which is to the northeast. See also List of rivers in British Columbia References Rivers of the Lower Mainland
