Nettilling Lake, Freshwater lake in Qikiqtaaluk Region, Canada
Nettilling Lake is a large freshwater body in the Arctic that contains numerous islands scattered throughout its eastern reaches while its western section remains deeper and mostly open water. The geography shifts noticeably between these two parts of the lake.
The lake was first systematically explored by Franz Boas in 1883, who documented the southern shore and created detailed records of this northern water system. That early scientific work provided the foundation for understanding this Arctic landscape.
The name comes from ringed seals that occasionally travel from the ocean through connected waterways into the lake. Local people have long recognized these animal movements and built this knowledge into the place's identity.
The lake stays frozen under ice for much of the year, so timing your visit depends on the season you choose. Getting there is challenging and requires specialized transportation built for extreme Arctic conditions.
Three fish species thrive in the cold waters here: Arctic char, ninespine stickleback, and three-spined stickleback. These fish display remarkable adaptations to the extreme Arctic conditions of the lake.
