NTPC plans to reconstruct the historical Taltson Winter Road from Fort Smith to Taltson that was used in the 1960s, 1970s, and 1980s to access the site for construction, maintenance, and upgrades. 

The Northwest Territories Power Corporation proposes to reopen the 56 km Taltson Winter Road from Fort Smith, NT to the NTPC Taltson Dam. Water will be diverted from several waterbodies to create ice for the road surface. 
Approximately 75% of the water diverted will be from the Slave River, approximately 20% will be from Gertrude Lake, and the remaining 5% will be from Little Bent Tree Lake. Other potential water sources are presented in the Taltson Winter Road Map
