Flight into Fortress Lake


Guided Fishing.
Our retreat is a place to escape, relax, and enjoy yourself. We know the lake and we will guide you to ensure you know where, how, when, and why to fish various tactics at key times. After time together, either fishing together or specifically guiding you, we invite you to check out a boat and explore, to enjoy your personal time. The bottom line, we’re here to help, yet want the pace to your trip to be what you want it to be, with as successful fishing as hoped. It’s an intimate setting and we strive to provide the service you desire while respecting your personal time. We simply find most people want the freedom to explore, to enjoy the lake, the scenery – that personal time.


What is the average size trout caught at Fortress Lake?
The lake’s population is extremely healthy.  During the 2022 season sizes were 3 to 5 pounds in appreciable numbers with a few larger fish present & a few 7 ponders caught. Again, per biological study, the Brookies in this lake put on an average of 2 pounds in their third year. Fewer small Brookies are caught as these fish grow rapidly thanks to considerable movement throughout the lake, making seasonal use of forage. The lake record is 11.75 pounds. Anglers can realistically hope for a few trout in the 5 pound range.


Is it ‘only’ lake fishing?
The Wood River – which flows out from Fortress Lake – provides some river fishing with good structure to work. There are light hatches and some dry fly fishing occurs. The Wood provides some of the most gorgeous scenery on the trip. 


About the weather?
We are located at the Continental Divide, surrounded by stunning mountains and glaciers with several of the highest peaks in the Canadian Rockies nearby. Our weather is influenced by the mountains and the weather can change often. During our season, late May through mid October, our weather is generally pleasant with temperatures in the 20 to 30C range (70 – 85F). Precipitation is not generally heavy nor long lasting during our year, but we do get rain. Guests should come prepared for rain and sun, with temperature extremes from freezing overnight (late in the season) to 35C (95F). While peak of summer temperatures can get to mid 30s C (90s F), the cool air of the glaciers drops the overnight temperatures beautifully each night.


Unlike most other mountain lakes, Fortress Lake is an east – west oriented lake with open valleys at either end. This means that we get the full range of sunshine through the day, we enjoy the full sunrise to the east and the full sunset to the west. During the day, the sun lifts well above the peaks surrounding the lake. On sunny days we enjoy full sunshine from first to last light, from opening week in May to early October. In June, fishable light is 4:30am until 11pm.


Where are you located and how do I get there?
For 2023 you can choose a Calgary or Cline River package. If you fly into Calgary we recommend you take the shuttle package from Calgary. We will pick you up at your hotel and take you to the Heli-pad. If you choose the Cline River package you will fly into the Calgary International Airport as well or can rent a car and travel approximately 3 hours to Cline River.


Biting bugs?

Fortress Lake Wilderness Retreat is surrounded by steep, rocky slopes and the shoreline is gravel. This is not a mosquito habitat and very few bother guests. Black flies common to other brook trout lakes in Ontario & Labrador/ Newfoundland do not exist due to the well drained gravel shorelines. There are some horseflies at the peak of summer and in wet years we do get sandflies. Most years there are very few bugs but there are one or two wet years per decade that see some bugs.
