History
Water levels of James Lake increased and decreased in the early 1900s.[1] The cause of this alternation could have been caused by beavers building dams in the lake's outlet, eventually causing the water levels in rise.[1] This rise in water levels began to cease in 1906 when operations of Northland Pyrite Mine on the lake's southwestern shore dumped waste rock into the lake.[1] Erosion of the waste rock resulted in the development of acidic lake waste waters next to the waste pile, causing neighboring organisms to disappear.[1]
