Iosegun Lake is a popular sport fishing lake set in heavily forested, gently rolling land. It is situated in Improvement District No. 16, 260 km northwest of the city of Edmonton, 82 km northwest of the town of Whitecourt and 8 km north of the town of Fox Creek. An industrial road from Fox Creek serves the east side of the lake (Fig. 1) and provides access to Iosegun Lake Forest Recreation Area.

The lake's name originates from a Cree or Stoney word for the Iosegun River that means either "tail" or "hash" (Alta. Cult. Multicult. n.d.). The lake was called Hash Lake by fur traders and natives in the early 1900s.

The native inhabitants in the area northwest of Whitecourt were Woodland Cree, but the Beaver tribe may have lived there at an earlier time (Olecko 1974). The region was close to an aboriginal migration route from Lac Ste. Anne to the Sturgeon Lake area, and sites on Iosegun Lake have traditionally been used as hunting and fishing bases. As well, four sites near the lake have been identified as burial grounds (Alta. For. Ld. Wild. 1988[b]).The first European to arrive in the area was probably David Thompson in 1799; he camped at a site that is now the Whitecourt townsite (Knapik and Lindsay 1983). Missionaries arrived in the region about 40 years later. Industrial development began in 1909 when logging and milling operations were initiated 10 km west of Whitecourt near the Athabasca River. The railroad arrived in Whitecourt in 1921, but was never completed to the Peace River Country, as originally proposed. The area near Iosegun Lake was not developed until oil and gas exploration in the 1950s brought the railroad as far as the Kaybob station, about 15 km south of the lake. Highway 43 opened in 1955, and was paved and completed in 1962 as far as the town of Valleyview, 70 km north of the lake. There have been no residential developments at the lake.

In 1988, a lake management plan for Iosegun Lake was completed by Alberta Forestry, Lands and Wildlife (Alta. For. Ld. Wild. 1988[b]). The plan assesses potential commercial and public recreational development of Iosegun Lake, based on environmental, social and economic constraints. It will be used as the basis for an area structure plan to guide development around the lake, which will be prepared by improvement District No. 16.

Iosegun Lake Forest Recreation Area was built in 1970 by the Alberta Forest Service and upgraded in 1986. It is located at the southeast end of the lake (Fig. 2), and serves as a staging area for the Alberta Forest Service's Iosegun Lake Snowmobile Trails. Facilities at the recreation area include 50 campsites, a day-use area with 10 picnic tables, a picnic shelter, pump water, a beach and a boat launch. Popular activities on and around the lake are power boating, wind surfing, fishing, picnicking, swimming, cross-country skiing and snowmobiling. There are no boating restrictions specific to Iosegun Lake, but general federal regulations apply (Alta. For. Ld. Wild 1988[a]).

Algal blooms turn the lake water green in late summer, and aquatic vegetation grows in shallow areas at the north end. High concentrations of organic matter reduce water clarity. The main catches of the sport fishery are walleye and northern pike. Iosegun Lake is closed to sport fishing during a designated period in April and May each year. As well, the lake's inlet and outlet streams are closed to fishing from September to mid-June each year (Alta. For. Ld. Wild. 1989). A commercial fishery operates in alternate years.
