Clearwater Lake Provincial Park

Summer (late June through August) is the primary season — the lake’s waters warm to comfortable swimming temperatures by mid-July (18-20°C at the surface despite the cold deep-water character of the lake trout zone), the campground is fully operational, and the lake trout fishing (trolling the deep central basin) is productive throughout the summer. Lake trout fishing is best in June and September (the fish are in shallower water and more accessible to shore anglers and shallow trollers in the cold-water months of spring and early fall; in July and August the lake trout descend to their thermal refuge in the 25-36-metre deep zone, requiring deeper trolling). Northern pike fishing is productive throughout the summer season in the shallower, warmer bays of the crater rim. The boreal forest surrounding the lake turns spectacular gold in late September and early October (the jack pine and tamarack colour is the finest display in the northern Manitoba Shield area). Spring (May through June) brings the ice-off (typically mid-May in most years) and the finest lake trout fishing of the year as the fish cruise the shallows in the cold post-ice period.

Clearwater Lake was formed approximately 290 million years ago (in the Permian period) by a meteorite impact that excavated the Precambrian Shield bedrock into the circular crater basin now occupied by the lake. The Cree people (specifically the Omushkego Swampy Cree) have inhabited the lake’s shores and surrounding boreal country for thousands of years — the lake was a food-gathering and travel hub on the Shield country of northern Manitoba. The town of The Pas (Opaskwayak in Cree, meaning “narrows of the river in the forest”) 20 kilometres south of the park has been a Cree community centre and fur-trade post since the early 18th century (the Hudson’s Bay Company established a post at The Pas on the Saskatchewan River; the town remains the service centre for a large region of northern Manitoba). Clearwater Lake Provincial Park was established in 1961, recognizing the lake’s exceptional natural and recreational values.

Clearwater Lake Provincial Park’s boreal and lake ecosystem supports a northern Manitoba wildlife community — the lake trout (the park’s ecological flagship — a cold-water apex predator that requires the clear, cold, oxygen-rich water of the deepest crater zones; the population sustains itself naturally in the lake’s exceptional habitat without stocking), northern pike (abundant in the warmer shallows and inlets of the crater rim), walleye (present in the lake in smaller numbers than pike and lake trout), beaver, river otter (the lake’s clear water makes otter fishing visible from the shore — otters hunting in 5-metre-clear water is a striking sight), osprey and bald eagle (fishing the lake’s shallows), common loon (the lake’s clarity and fish abundance make it excellent loon habitat), moose (in the boreal muskeg surrounding the crater rim), and the boreal songbird community. The lake’s fish community — lake trout, pike, and walleye in a naturally balanced predator-prey system sustained by exceptional water quality — is the ecological centerpiece.

Clearwater Lake is one of Manitoba’s most ecologically sensitive lakes precisely because of its exceptional clarity and oligotrophic character — the lake’s ecosystem is sustained by the near-total absence of nutrient input from the surrounding Precambrian crater-wall geology, and any nutrient enrichment (from boat fuel, sewage, or shoreline disturbance) would directly degrade the clarity and the lake trout habitat quality that defines the park. The surrounding boreal forest (black spruce, jack pine, and tamarack on the muskeg soils of the crater rim) is in a natural fire-succession cycle — the northern boreal forest is maintained by periodic fire, and the park’s management allows natural fire processes where consistent with visitor safety. The lake’s geology (the impact crater and its shatter-cone outcrops) is a scientifically significant geological resource that is not found in comparable form elsewhere in Manitoba.

Clearwater Lake is a place of dual significance — a geological marvel (one of the clearest and most perfectly circular impact-crater lakes in Canada, with shatter-cone outcrops accessible to any park visitor) and a northern Manitoba fishing destination of long tradition (the lake trout fishery has been attracting anglers from The Pas and Winnipeg since the park’s establishment in 1961). The Cree heritage of The Pas and the surrounding region (the Opaskwayak Cree Nation is the largest First Nation community adjacent to the park; the Northern Manitoba Trappers’ Festival in The Pas, held each February, is one of Manitoba’s most celebrated Indigenous cultural events) provides the cultural context for the park. Clearwater Lake represents a northern Manitoba tradition of driving or flying north from the agricultural south to fish in clear, cold, northern lakes — a tradition as old as the province.

Clearwater Lake Provincial Park is accessed from The Pas, Manitoba (20 kilometres south on Highway 287 from the park entrance; The Pas is 600 kilometres northwest of Winnipeg on Highway 16 west and Highway 10 north, a 6-7 hour drive from Winnipeg). The Pas is the service centre for northern Manitoba with full services including grocery, fuel, accommodation, and an airport (scheduled air service from Winnipeg on Calm Air). The park campground (on the lake’s southern shore, accessible by park road from Highway 287) is the primary visitor facility; campsites can be reserved through Manitoba Parks online. Boat launch facilities on the lake’s southern shore allow launching of private boats and motors (motor size restrictions may apply — check Manitoba Parks). Canoe and small-boat rental may be available from The Pas-area outfitters; confirm availability before arrival.

Manitoba Conservation manages Clearwater Lake Provincial Park. The lake’s exceptional water clarity and oligotrophic character are the primary conservation values to protect — all boaters must use clean, properly maintained engines (four-stroke motors strongly preferred to minimize fuel contamination); no washing of vehicles, dishes, or clothing in the lake; no use of soaps or detergents within 30 metres of the shoreline; pack out all garbage from the lakeshore and campground. The lake trout population is protected by Manitoba Conservation fishing regulations specific to Clearwater Lake (minimum size limit, daily bag limit — check Manitoba Conservation before fishing; the regulations are more conservative than standard Manitoba lake trout regulations to protect the naturally reproducing population). The shatter-cone outcrops along the lake’s shoreline are scientifically significant geological heritage — no collection of shatter-cone specimens (removing geological specimens from Manitoba provincial parks is illegal).

Clearwater Lake’s depth (36 metres maximum) and oligotrophic character mean the water is cold even in summer at depth; lake trout fishing in the deep zone involves the cold-water immersion risk common to all deep cold lakes — wear a PFD on the water at all times. The lake’s large surface area (700 square kilometres) allows wind-driven wave development; motorized boaters should monitor weather and return to shore when winds strengthen. The surrounding boreal forest (black spruce and tamarack muskeg) is wet and can be disorienting for hikers who leave marked trails; stay on designated trails and carry a map and compass. Black bears are present in the park’s boreal surroundings — follow standard bear-country food-storage practices at the campground. The drive from Winnipeg (6-7 hours, including the Highway 10 section through the Pas Lowlands) should be planned with adequate fuel stops (services are sparse north of Dauphin on Highway 10).

Manitoba Parks entry and camping fees apply (reserve campsite through Manitoba Parks online — the campground is popular with The Pas-area families and fills on summer weekends). Manitoba fishing licence required; check Manitoba Conservation for Clearwater Lake-specific lake trout size and bag limits (more conservative than standard regulations). Motor size restrictions may apply on the lake — check Manitoba Parks before launching. No collection of rocks, minerals, or geological specimens (including shatter cones) from the park. No use of soaps or detergents within 30 metres of the lake. Campfires in designated fire rings only; fire bans apply in dry conditions (check Manitoba Conservation before arrival). Dogs on leash in all park areas. Check Manitoba Parks for current regulations, fire bans, and campsite availability.

The Pas (20 kilometres south — the largest community in northern Manitoba, with full services, the Opaskwayak Cree Nation community across the river, the Northern Manitoba Trappers’ Festival in February, and the E.H. Ironside Museum of local history), Clearwater Lake Outfitters and local guide services (ask at The Pas visitor centre for current operating outfitters offering lake trout and pike fishing guide service on the lake), Moose Lake Provincial Park (60 kilometres east of The Pas — another northern Manitoba fishing and camping park in the boreal Shield), and the Saskatchewan River (passing through The Pas — a productive northern pike and walleye river with boat launch facilities in The Pas) round out the regional context. Thompson, Manitoba (160 kilometres northeast of The Pas on Highway 6 — Manitoba’s third-largest city, the service centre for the northern Shield, with a full-service hospital and airport) is the broader regional hub.

Make time to find and examine the shatter cone outcrops on the lake’s shoreline — the conical, striated rock fractures produced by the 290-million-year-old meteorite impact are visible in the granite outcrops along the water’s edge near the campground; ask the park staff to direct you to the best accessible exposures. The shatter cones are one of the most tangible pieces of geological history visible to any visitor in Manitoba — holding a piece of rock fractured by a meteorite impact 290 million years ago is a remarkable experience, even if you cannot take it home. For lake trout fishing, hire a local guide from The Pas who knows the lake’s deep-water structure and seasonal fish movements (lake trout in Clearwater follow a predictable depth-temperature pattern through the season; a knowledgeable guide will put you on fish in the deep central basin immediately rather than the exploratory trolling that a first-time visitor would otherwise require). Book your campsite months in advance for any July or August weekend.
