TheJackfish Point andBistcho Lakeindian reserves of theDene Tha'First Nation are established on the southern shore of the lake.
In May of 2021 the Dene Tha' First Nation formally proposed anIndigenous Protected and Conserved Area (IPCA) that would be centred on the lake but include much of the northwestern corner of Alberta.[2] In preparation for the proposed IPCA, the First Nation did extensive archaeological surveys of the shores of the lake, demonstrating continuous use of the lake by indigenous hunters and fishers for thousands of years.[3]
