McArthur Lake is a lake in Ontario, Canada to the south of the city of Timmins. The lake has a rocky shoreline and 13 islands. It is used for recreation in the summer, but freezes in the winter. Due to the harsh climate most of the trees around the lake are conifers. The rocks around the lake have potential for nickel extraction.

Geography

McArthur Lake (FCEHV) is located in Timiskaming District, [1] about 40 kilometres (25 mi) south of the city of Timmins. [2] Most of the lake lies in McArthur township, [3] but the eastern part extends into Douglas Township. [4]

It has an elevation of 333 metres (1,093 ft) above sea level. [5] It has an area of about 1.5 square kilometres (0.58 sq mi), with a maximum depth of about 35 feet (11 m).

Islands in the lake include:

Some of the bays in the lake include:

Climate

The lake is in the Hemiboreal climate zone. [6] Annual average temperature is 1 °C (34 °F). The warmest month is July, when the average temperature is 16 °C (61 °F), and the coldest is January, with an average temperature of −18 °C (0 °F). [7] Annual average rainfall is 904 millimetres (35.6 in). The wettest month is August, with an average of 128 millimetres (5.0 in) and the driest in February, with 11 millimetres (0.43 in). [8]

Environment

McArthur Lake has a rocky shoreline with three main bays and thirteen islands. [2] The west side of the lake has more than 20 camps and cottages. [2] It is used for kayaking, boating and fishing for walleye and northern pike. [2] The lake is frozen over during the winter. In July surface water temperatures may reach 25 °C (77 °F). Trees include cedars and poplars, balsam firs and pines of various types, but few deciduous trees. [2]

Total phosphorus concentration was measured at two sites in the lake in 2004–2007. Average levels were: [9] [10]

DateWest end, deep spot

µg/L
31 May 20046.696.52
16 May 20056.095.41
17 May 20077.286.63

Since these all levels are below 10 µg/L the lake is considered oligotrophic and unlikely to experience nuisance algal blooms. [10]

Geology

The lake lies in a zone of ultramafic metavolcanic rocks (Komatiites) known as the Tisdale Assemblage. [3] The southwest corner crosses a northwesterly trending quartz-bearing diorite sill of intermediate intrusive rocks. [3] [11] The southern part of the lake is crossed by two diabase dikes of the Sudbury dike swarm. [3] The dykes have 12% plagioclase, 20% tremolite, 35% clinopyroxene, 8% chlorite, 18% sericite, 3% magnetite and 2% calcium-garnet. [12] Outcrops of high magnesium ultramafic rocks of the Goose Lake Formation are found south and northwest of the lake. [13]

In the south of the lake, gold is reported to be found, although exploration work has consisted almost entirely of trenching. [14] The lake is mostly contained within the McArthur Lake Nickel Property owned by Eloro Resources Ltd.. Eloro acquired this property, which covers about 30 square kilometres (12 sq mi), in 2007 via claim staking after an airborne geophysical survey showed magnetic continuity with the Texmont nickel-bearing lithologies to the south.
