Frame Lake

Frame Lake is located in Yellowknife, Northwest Territories, Canada. It is an 84-hectare endorheic freshwater body located between the city's downtown section and a larger residential area. The Frame Lake Trail circles it, and city hall and the territorial legislative assembly building are on its shores.

Formed by meltwater after the end of the Wisconsin glaciation 20,000 years ago, Frame has been an important part of Yellowknife's history. The Dene in the area used it as a fishing spot before European settlement. In the early years of the city's growth, gold mines nearby dumped tailings in it and sometimes sewage. Later, when the city's New Town, now its downtown section, was surveyed and developed nearby, Frame offered accessible swimming and boating opportunities.
