The Atlantis of Banff, Scuba Dive to the Park’s Hidden Gem

Scuba Diving in Lake Minnewanka

Maybe not the first place you would check for scuba diving opportunities, but Banff National Park actually has two interesting ones in particular: Two Jack Lake and Lake Minnewanka, both close to the town of Banff. Especially the latter is fascinating, much more than you would ever imagine. Read on to find out why. 

Ok, let’s give you the answer straight away: Lake Minnewanka is home to an old, submerged dam, bridge and a submerged resort town. No kidding, an actual sunken city in the Rocky Mountains. And accessible to you if an experienced scuba diver.  

Once flourishing at the lake’s shore, this townsite remains mainly intact and attracts scuba divers from all over the world. It’s obviously the main focus of all divers who come to dive in the park.

You can dive in other places too, but these locations come nowhere close to Lake Minnewanka’s hidden treasure. Eager to know more?

Let’s have a look at what diving in Banff National Park entails for scuba diving enthusiasts.  

Scuba Diving at Two Jack Lake

Diving in Two Jack Lake is perfect for newbie scuba divers who want to hone their skills, as the lake is relatively shallow. It has three different areas for diving. They are all shore dives.

The visibility in the lake ranges from 5 to 10 meters (16 – 32 ft), varying with the time of the year. The lake’s depths are primarily in the 6-meter range (20 ft), with 15 meters (50 ft) at the bottom.

There’s not much to see underwater. You’ll find some barrels and cables (remains of an old dock system), see some freshwater shrimps and trouts, and some grassy weeds bed. 

Once you’ve trained at Two Jack Lake and feel confident enough, head over to the adjacent Lake Minnewanka, Banff National Park’s biggest lake, to discover the submerged town of Minnewanka Landing (see the section below).    

Two Jack Lake
Altitude: 1475 m (4839 ft)
Depth: 15.2 m (50 ft) 
Length: 4.61 km (2.85 mi)
Surface: 0.21 km (0.13 sq. mi)

Scuba Diving at Lake Minnewanka

Lake Minnewanka scuba diving represents an extraordinary experience. First and foremost, the lake is the location of the submerged town Minnewanka Landing which existed from 1886 until 1941. Due to dams in the lake, the former resort town at the shore got submerged and became the Atlantis of the Rockies.

I’m sure that makes you want to dive Lake Minnewanka.

Because ever since the lake has become the number one spot for an exciting scuba diving experience. The town has remained intact quite well due to the protective character of the water.

Old Dam and Minnewanka Landing

The lake has two main dive sites: the fully intact old dam – containing a pump house through which you can swim – and the submerged townsite of Minnewanka Landing.

The latter site is typically accessed by boat. You can rent one at the lakeshore. When you reach the old townsite, you’ll be able to see a hotel, house foundations, breakwaters, bridge foundations and wharves.

To get to these points of interest, you need to cover some distance: About 6 to 9 meters (20-30 ft) for the dam to 30 meters (100 ft) for the townsite. These depths, however, are not set in stone as Lake Minnewanka is a dammed lake.

As a result, water levels can vary significantly. Also please note that diving here is considered advanced diving.

The Parks Canada site warns to leave the town untouched as it qualifies as Canadian cultural heritage. Therefore it’s also not allowed to take any historic or prehistoric artifacts from the site. Removing, destroying or damaging an artifact may result in a CAD 2000 fine.

Lake Minnewanka
Altitude: 1450 m (4757 ft)
Depth: 142 m (466 ft)
Length: 18 km (11.16 mi)
Surface: 22 km2 (8.49 sq. mi)

One person must remain on board when the other is submerged in the lake’s water. You should also fly a fully visible dive flag when in the water.
