Selkirk Water Hardness & Quality Report (2026)

Selkirk's drinking water is managed by the City of Selkirk, drawing from the Red River — Selkirk is a city north of Winnipeg on the east bank of the Red River in Manitoba, the 'Catfish Capital of the World' for its world-class Red River channel catfish sport fishing, home to the Marine Museum of Manitoba (housing the largest collection of inland freshwater vessels in Canada), the historic Lord Selkirk Park regional park on the Red River, and the Selkirk Mental Health Centre heritage campus (the former Provincial Hospital for the Insane, designed in the Kirkbride 'bat wings' cottage plan style). Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, fully meeting the Guidelines for Canadian Drinking Water Quality (GCDWQ). Hardness measures 194 mg/L (11.3 gpg) — classified as very hard by Health Canada, consistent with the Manitoba Red River basin supply.

Selkirk draws from the Red River — the Red River in the Manitoba lowlands carries highly dissolved minerals from the Cretaceous Williston Basin evaporite and carbonate sediments of the Red River valley, including the Ordovician Red River Formation dolostone and the Silurian Interlake Group which form the subsurface source of the dissolved calcium and magnesium. At 194 mg/L, Selkirk is at the lower end of the Manitoba supply range (Winnipeg ~200 mg/L from reference data), consistent with the Red River north-bank supply. The 'mixed' waterSource designation confirms a blend of river and local groundwater components.

At 194 mg/L, Selkirk homeowners face persistent scale challenges — monthly to bimonthly kettle and showerhead descaling is typical. Hot water tanks benefit from periodic inspection. The City of Selkirk provides water quality information at cityofselkirk.ca. Health Canada lead precautionary guidance applies to pre-1975 properties in the historic Selkirk downtown and the established Red River bank residential neighbourhoods.
