Not taking any guesses about roads, water and summer this year. The creek is running low today, likely because of the colder temps in the mountains. Fresh snow in the mountains too. So when it starts to melt, water will rise quickly again.
Last June a washout near Rancheria (between Watson Lake & Teslin) delayed travellers for four days until a temporary bridge could be installed. This March when we drove south, the temp bridge was still in place and the highway was still a gravel construction zone.
Nothing went north or south for those four days in June. The Cassiar Highway was also washed out, as well as the Campbell Highway. Store shelves in Whitehorse went bare and some gas stations ran out of fuel.
The crews are still working on this recent road damage BUT one never knows what/where/when another will flood.
Keep fuel on the top half of your tank, and have a well-stocked pantry so you can eat well enough if a delay is encountered.
