Koocanusa Lake real estate — your questions answered
Where is Lake Koocanusa?
Along the BC-Montana border south of Cranbrook. Created by Libby Dam (Montana) on the Kootenay River. The name combines KOOtenay + CANada + USA.
Cross-border issues?
Lake straddles the international border — properties are in BC. Cross-border boating requires US Customs clearance if entering Montana waters. Many BC owners stay on the Canadian side.
What BC taxes apply to waterfront purchases?
BC charges Property Transfer Tax (1-3% sliding). Foreign Buyers Tax (20%) applies to non-resident purchases. Speculation and Vacancy Tax (0.5-2% annually) applies in many areas. Riparian Areas Regulation requires 30-metre setbacks.
What's the BC cottage season?
BC's Kootenay lakes have long open-water seasons — typically April through October. Higher-elevation alpine lakes thaw later. Many properties are usable year-round, with winter activities varying by elevation.
