About This Dive Site
Ice diving at Lake Minnewanka, permitted by Parks Canada, transforms the reservoir into a winter wonderland with stable ice up to 60cm thick by January. Dive under ice shelves at Townsite or shallower entry points, depths 5-12 meters (16-39 feet), zero visibility common, eerie silence. Altitude 1450 meters adds complexity; ice forms November-March, best February. Access via groomed trails from Lake Minnewanka parking; hole drilling required.
Safety Considerations
Strict Parks Canada rules: AIS clean/dry gear, ice-specific permit. Ice diving certification mandatory (PADI Ice Diver); tender on surface with ropes, saws. Hypothermia extreme in sub-zero air (-10°C/14°F) and 2-4°C (35-39°F) water; limit bottom time 20-30 minutes. Overhead environment demands redundant lights, air, comms. Alberta Underwater Council flags for hole marking. Test ice thickness (min 30cm/12in per standards); avalanche risk from slopes. No solo dives; two tenders minimum. REI emphasizes self-rescue drills.
Essential Gear
Drysuit (Sailfish Ice), double tanks manifolded (Kirby Morgan), primary/backup lights (Halcyon), comms umbilical, ice screws, shovel, siren, heated tent, dry gloves (Fourth Element), full redundancy regulator (Poseidon), surface air supply line.
