Last Mountain Lake

Geographical features

Several creeks and rivers flow into the lake, including Arm River, Lewis Creek, and Lanigan Creek. Last Mountain Creek flows out of the lake at the southern most point and into the Qu'Appelle River. During years in which the Qu'Appelle River's level is high, the Last Mountain Creek can reverse direction and flow back into Last Mountain Lake. The gates at Craven Dam on the Qu'Appelle River can be opened or closed to control the water level, and closing those gates can also cause water to flow back up the creek into the lake.

Named islands at the northern end of the lake include Royal Island, Bird Island, and Coney Island.

Near the southern end of the lake on the west side is Little Arm Bay, the outlet of the Arm River. Directly across from the bay is Pelican Point. The community of Pelican Pointe is located there.

Last Mountain Lake Sub-basin

The Qu'Appelle River watershed has two main basins, one called the Wascana & Upper Qu'Appelle Watersheds, the other the Lower Qu'Appelle Watershed. Craven Dam at the village of Craven is the dividing point between the upper and lower watersheds of the Qu'Appelle River. The upper watershed, which has a total area of 23,443 km² (9,051 sq mi), has four sub-basins: Last Mountain Lake Sub-basin, Lanigan-Manitou Sub-basin, Wascana Creek Sub-basin, and Upper Qu’Appelle Sub-basin; it also includes the Moose Jaw River Watershed. Last Mountain Lake Sub-basin includes all the land that drains into the lake from the east and west, including Arm River and Lewis Creek. Lanigan Creek at the north end of the lake is part of the Lanigan-Manitou Sub-basin, and Last Mountain Creek at the south end is part of the Upper Qu’Appelle Sub-basin.

Parks and recreation

About 25 kilometres (16 mi) south-west of the town of Strasbourg, along the lake's eastern shore, lies Rowan's Ravine Provincial Park. This park includes a marina, a full-service campground, restaurant, mini-golf, beach, and an outfitters. The beach is along a point and is one of Saskatchewan's longest, natural sand beaches. The marina there is often used by recreational boaters travelling from Regina Beach as a stop-over or refuelling point and large fishing tournament called Last Mountain Fall Walleye Classic is held there every September. Last Mountain House Provincial Park is located on the south-east shore and provides tours of historical the Last Mountain House, which was built by the Hudson's Bay Company in 1869.

At the northern end of the lake, on the eastern shore is Last Mountain Regional Park. The park offers camping, swimming, and golf. It is located about 15 kilometres (9.3 mi) west of Govan, off Highway 20.

At the southern end of the lake, where Last Mountain Creek starts, is the Valeport Recreation Site and Valeport Marsh. The area is protected by a 900-acre conservation project called Valeport Wildlife Management Area Trails. It is in conjunction with Ducks Unlimited and part of the Valeport Marsh (SK 061) Important Bird Area (IBA) of Canada. Along the west side of the Management Area is a Nature Conservancy of Canada property called Big Valley. Big Valley is protected and managed for bird and wildlife habitat.

The United Church of Canada's Lumsden Beach Camp is "[a] short drive from Regina, ... hugging the south shore of Last Mountain Lake." Founded in 1905, it is the oldest summer camp in Western Canada.

Last Mountain Lake Bird Sanctuary

The Last Mountain Lake Bird Sanctuary, the first federal bird sanctuary in North America, was established here in 1887. As the first such wildlife reserve of this kind on the continent, it was designated a National Historic Site of Canada in 1987. Over 280 bird species have been recorded. The lake contains appropriate habitat for nine of Canada's 36 species of vulnerable, threatened and endangered birds, such as the peregrine falcon, piping plover, burrowing owl, and whooping crane.

The northern end of the lake is very shallow and contains wetlands. Part of this area of the lake and surrounding area has been set aside as the Last Mountain Lake National Wildlife Area, which is a site of regional importance in the Western Hemisphere Shorebird Reserve Network.

Fish species

Fish species commonly found in Last Mountain Lake include walleye, yellow perch, northern pike, burbot, lake whitefish, cisco, bigmouth buffalo, white sucker, and common carp.
