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. GeographyMcArthur Lake (FCEHV) is at {{coord|48.2061111|-81.2155556|region:CA_type:waterbody|display=inline}} in Timiskaming District.{{sfn|McArthur Lake – Natural Resources Canada}} Most of the lake lies in McArthur township.{{sfn|Houlé|2007}} The eastern part extends into Douglas Township.{{sfn|McArthur Lake Nickel Property – Eloro}} It has an elevation of {{convert|333|m}} above sea level.{{sfn|McArthur Lake Topo Maps – Yellow Maps}} It has an area of about {{convert|1.5|km2}}, with a maximum depth of about {{convert|35|ft}}. The lake is about {{convert|40|km}} south of the city of Timmins.{{sfn|McArthur Lake – Mapio}} Islands in the lake include: {{div col|rules=yes|colwidth=15em}}
ClimateThe lake is in the Hemiboreal climate zone.{{sfn|Peel|Finlayson|McMahon|2007}} Annual average temperature is {{convert|1|°C}}. The warmest month is July, when the average temperature is {{convert|16|°C}}, and the coldest is January, with an average temperature of {{convert|-18|°C}}.{{sfn|Dataset Index – NEO}} Annual average rainfall is {{convert|904|mm}}. The wettest month is August, with an average of {{convert|128|mm}} and the driest in February, with {{convert|11|mm}}.{{sfn|Rainfall (1 Month - TRMM) – NEO}} EnvironmentMcArthur Lake has a rocky shoreline with three main bays and thirteen islands.{{sfn|McArthur Lake – Mapio}} The west side of the lake has more than 20 camps and cottages.{{sfn|McArthur Lake – Mapio}} It is used for kayaking, boating and fishing for walleye and northern pike.{{sfn|McArthur Lake – Mapio}} The lake is frozen over during the winter. In July surface water temperatures may reach {{convert|25|C}}. Trees include cedars and poplars, balsam firs and pines of various types, but few deciduous trees.{{sfn|McArthur Lake – Mapio}} Total phosphorus concentration was measured at two sites in the lake in 2004–2007. Average levels were:{{sfn|McArthur Lake (Stn 3064, Site Id 1}}{{sfn|McArthur Lake (Stn 3064, Site Id 2}}
Since these all levels are below 10 µg/L the lake is considered oligotrophic and unlikely to experience nuisance algal blooms.{{sfn|McArthur Lake (Stn 3064, Site Id 2}} GeologyThe lake lies in a zone of ultramafic metavolcanic rocks (Komatiites) known as the Tisdale Assemblage.{{sfn|Houlé|2007}} The southwest corner crosses a northwesterly trending quartz-bearing diorite sill of intermediate intrusive rocks.{{sfn|Houlé|2007}}{{sfn|Tabatabai|1978|p=9}} The southern part of the lake is crossed by two diabase dikes of the Sudbury dike swarm.{{sfn|Houlé|2007}} The dykes have 12% plagioclase, 20% tremolite, 35% clinopyroxene, 8% chlorite, 18% sericite, 3% magnetite and 2% calcium-garnet.{{sfn|Tabatabai|1978|p=40}} Outcrops of high magnesium ultramafic rocks of the Goose Lake Formation are found south and northwest of the lake.{{sfn|Tabatabai|1978|p=23}} In the south of the lake, gold is reported to be found, although exploration work has consisted almost entirely of trenching.{{sfn|Breaks|1978|p=41}} The lake is mostly contained within the McArthur Lake Nickel Property owned by Eloro Resources Ltd.. Eloro acquired this property, which covers about {{convert|30|km2}}, in 2007 via claim staking after an airborne geophysical survey showed magnetic continuity with the Texmont nickel-bearing lithologies to the south.{{sfn|McArthur Lake Nickel Property – Eloro}} See also
