Croucher Creek is a small tributary of the Yukon River located near Whitehorse, Yukon, entering the Yukon River approximately 2.2 kilometers downstream of the mouth of McIntyre Creek on the east bank. This creek holds a fascinating ecological significance as a non-natal stream for chinook salmon — adult chinook do not spawn within the creek itself, but juvenile fry migrate up from the Yukon River during summer to rear and overwinter in its waters. This unique behavior makes Croucher Creek an important piece of the upper Yukon watershed's fish ecology. The creek features both a north fork and a south fork, with the south fork containing a notable beaver pond area known as Beaver/Livingstone Pond. The creek flows through terrain characterized by beaver damming activity in its lower reaches, and its watershed sits within close proximity to the city of Whitehorse.
