The District of Lake Country draws from several sources, and its 2025 report lists hardness for raw source water sampled in August 2025. Kalamalka Lake tested 176 mg/L, Okanagan Lake 129, Coral Beach 130 and Lake Pine 128. Oyama Creek was much softer at 20.8 mg/L. These are not tap values. Treatment does not remove hardness, but which source serves your address decides what you get.
Health Canada: hardness above 200 mg/L is considered poor but tolerable; above 500 mg/L unacceptable.

What it means at home
- Fast scale on taps, shower screens and kettle; white spots on glassware.
- Water heater: efficiency loss and element failures within years if unprotected.
- Dry skin and dull hair after showering are common.
- Softener recommended; jug or reverse osmosis for drinking.
How much salt will you use for softening?
Recommended, especially with a heater or boiler: scale cuts efficiency and shortens its life.
Descale a coffee machine or kettle about every 2 months (typical manufacturer guidance for this hardness).
