Everything you need to know about this dive site.

Divers should confirm local access conditions before travelling, especially outside the main recreation season.
Typical diving depths range from about 6–17 m / 20–55 ft, with a deeper spot reported around 19 m / 62 ft. The ALMS lake report records a maximum lake depth of 18.59 m / 61 ft, which aligns closely with local diver records of the deep spot.

Best Time to Dive
Planning a Clear Lake dive means prioritizing your preferred conditions, as seasonal changes significantly influence the experience. For clearest visibility, spring is often recommended before rising summer temperatures trigger plankton blooms; however, water temperatures will be at their coolest then. Summers typically offer warmest water, making for more comfortable wetsuit diving, though visibility may diminish. Autumn months, prior to the "big freeze," also provide viable diving windows. During prime diving seasons, average air temperatures range from 15.5-18°C / 60-64°F in summer (June-August) to 15°C / 59°F in September, cooling to 5.5°C / 42°F in October. Rain averages are moderate across these months, with June seeing around 2.88 mm and July/August closer to 1.5 mm. Diving is generally not advised during winter months, as the lake freezes over.

Dive Experience & Conditions
From the public beach, divers usually begin with a surface swim before descending toward the underwater course. The course is marked with yellow nylon lines, which can help with navigation but also require streamlined equipment to avoid snagging hoses, gauges, or accessories. Bottom conditions can be silty, so visibility may drop quickly if divers fin too close to the lakebed. Maintain close buddy contact, use controlled kicks, and avoid disturbing the bottom around the training course. Clear Lake's name refers to its oligotrophic nature rather than consistently excellent dive visibility; particulate and plankton matter can significantly limit sight, especially beyond 10 feet. Clear Lake can stratify in summer. Some reports recorded a thermocline around 7 m / 23 ft in June and July, shifting shallower in August and deeper again by September. Surface water reached about 21.4°C / 70.5°F in August, but deeper water cooled quickly below the thermocline.
Dive Difficulty & Safety Guidelines
For a safe and responsible dive at Clear Lake, prioritize meticulous planning and adherence to local regulations. Always fly a dive flag, especially at locations like the Wainwright site where power boat traffic is a hazard. Given the potential for reduced visibility due to silt or plankton, maintaining close buddy contact is essential throughout the dive. Divers at the Wainwright course should also be mindful of 1/4" yellow nylon ropes marking underwater features to prevent entanglement of dangling equipment. Emergency planning should be done before the dive. Local emergency services are available through 911, and the nearest hyperbaric chamber is in Edmonton's Misericordia Community Hospital (780-970-5611).
