Last Mountain Lake

Last Mountain Lake,[3] also known as Long Lake, is a prairie lake formed from glaciation 11,000 years ago. It is located in south central Saskatchewan, Canada, about 40 kilometres (25 mi) north-west of the city of Regina. It flows into the Qu'Appelle River via Last Mountain Creek,[4] which flows past Craven. It is approximately 93 km (58 mi) long, and 3 km (1.9 mi) wide at its widest point. It is the largest naturally occurring body of water in southern Saskatchewan. Only Lake Diefenbaker, which is man-made, is larger. The lake is a popular resort area for residents of south-eastern Saskatchewan.

History

In the late 1800s, access to the area for farming and settlement was opened up by the Qu'Appelle, Long Lake and Saskatchewan Railroad and Steamboat Company which also operated steamships on the lake.[5]

Last Mountain Lake is named in honour of a Plains Cree legend about the Great Spirit shovelling dirt from the valley the lake now occupies and forming Last Mountain Hills, east of Duval and Strasbourg.[6]

Last Mountain House
Main article: Last Mountain House Provincial Park

"Last Mountain House" was a Hudson's Bay Company (HBC) trading post from 1869 to 1871. It was a branch of Fort Qu'Appelle 75 kilometres (47 mi) east and was about 85 kilometres (53 mi) south-west of Touchwood Hills Post. It was founded in part to compete with the increasing number of independent traders in the area and because the buffalo had moved south from Touchwood Hills. Some time after the second season the post was completely destroyed by fire and was not rebuilt. The House was located on the east side of Last Mountain Lake, about 1.6 kilometres (0.99 mi) north of the lake's outlet, 75 kilometres (47 mi) north-west of Craven, and about 40 kilometres (25 mi) north-west of Regina. The area is now part of Last Mountain House Provincial Park[7] and on the Canadian Register of Historic Places.[8]

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.[9] The gates at Craven Dam on the Qu'Appelle River can be opened or closed for water level control measures. When they're closed, it can backflood water up Last Mountain Creek and into Last Mountain Lake.[10]

Named islands at the northern end of the lake include Royal Island, Bird Island, and Coney Island.[11]

Near the southern end, on the west side of the lake, is Little Arm Bay, of which the Arm River flows into. Directly across from the bay is Pelican Point.[12] The community of Pelican Pointe is located there.[13]

Last Mountain Lake Sub-basin

The Qu'Appelle River watershed is divided into two main basins, the Wascana & Upper Qu’Appelle Watersheds and 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 is divided into four sub-basins and the Moose Jaw River Watershed,[14] of which Last Mountain Lake Sub-basin is one. The other three sub-basins include Lanigan-Manitou Sub-basin, Wascana Creek Sub-basin, and Upper Qu’Appelle Sub-basin. Last Mountain Lake Sub-basin includes all the land that drains into the lake from the east and west sides of the lake, including Arm River and Lewis Creek. Lanigan Creek at the north end 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. The total size of all four sub-basins and the Moose Jaw River Watershed combined is 23,443 km2 (9,051 sq mi).[15]

Communities

Eight different rural municipalities border at least part of the lake. Clock-wise from the north, RMs include Wreford, Last Mountain Valley, McKillop, Longlaketon, Lumsden, Dufferin, Sarnia, and Big Arm.

Resort communities such as Kannata Valley, Arlington Beach, Grandview Beach, Eldora Beach, Regina Beach, Saskatchewan Beach, Buena Vista, Glen Harbour, Alice Beach, Wee Too Beach, Alta Vista, Colesdale Park, Spring Bay, Pelican Pointe, Sunset Cove, Island View, Sorensen Beach, Etters Beach, Mohr's Beach, North Colesdale Park, and Sarnia Beach are on the shores of the lake.[16]

Beside Regina Beach, around Little Arm Bay, is Last Mountain Lake 80A Indian reserve.[17]

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 at the 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.[18] 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 Valeport Marsh. The area is protected by a 900-acre conservation project called Valeport Wildlife Management Area Trails.[19] It is in conjunction with Ducks Unlimited and part of an Important Bird Area (IBA) of Canada labelled Valeport Marsh (SK 061). 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.[20]

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.[21]

Last Mountain Lake Bird Sanctuary
Main article: 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.[22] 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.[23][24]

Fish species

The lake contains a host of fish species including walleye, yellow perch, northern pike, burbot, lake whitefish, cisco, bigmouth buffalo, white sucker, and common carp.
