Musreau Lake is a mesotrophic lake in northwestern Alberta, located approximately 70–85 kilometres south of Grande Prairie via Highway 40, then 2–4 kilometres east on a gravel access road. The lake covers roughly 1,380 acres with a shoreline of approximately 8.6 miles, making it a moderately sized body of water well suited to a half-day or full-day paddle. The lake is spring-fed, producing clear, deep water that is notably cold even in summer. It drains via Musreau Creek to the Kakwa River and then the Smoky River. A smaller body of water, Little Musreau Lake, lies directly to the west and is connected by a short unnamed creek, both falling within the boundaries of Musreau Lake Provincial Recreation Area, established in 1978.

The primary access point for paddlers is the boat launch located in the day-use area, which was relocated in 2010 to reduce congestion near the beach. Canoes and kayaks can be launched here alongside motorized craft. Power vessels are prohibited in the beach area specifically, so paddlers should be aware of motorboat traffic elsewhere on the lake. The lakeshore trail, while unmaintained, follows the perimeter and provides a reference for paddlers exploring the shoreline. The surrounding landscape is mature boreal forest, and wildlife viewing opportunities exist throughout the area.

Fish species present in the lake include bull trout, burbot, longnose sucker, rainbow trout, and white sucker, which may be of interest to paddlers who combine fishing with their outings. The lake's clear water and forested shoreline give it a distinctly boreal character. Visitor reviews note the water is quite cold, requiring time to acclimate even during the warmest months, which is relevant for paddlers considering capsize risks.

The recreation area is most active in summer. Summer mornings tend to offer calmer water and fewer generators from the campground, while weekday visits generally mean lighter crowds. The gravel road leading to the park is frequently rough, so paddlers should plan vehicle and trailer clearance accordingly. Facilities at the day-use area include a boat launch, picnic tables, firepits, pit/vault toilets, and a water cistern. Off-highway vehicles are prohibited within the park. The name Musreau is of Cree origin, with one meaning referencing a young moose — fitting given the moose habitat in the surrounding boreal forest.
