Egnell Creek is a tributary of the Hackett River in northwest part of the province of British Columbia, Canada.

[7][8] Egnell Creek's watershed covers 121 km2 (47 sq mi),[5] and its mean annual discharge is estimated at 1.95 m3/s (69 cu ft/s).

The creek flows southwest through Level Mountain's high and relatively barren lava plateau.

After about 8 km (5.0 mi) Egnell Creek enters a steep canyon carved into the escarpment on Level Mountain's western side.

[8][16] Subsequently, a number of buildings and a mission house were constructed and the name changed to Sheslay.

[15] In 1891–1892, the HBC constructed a trail from the mouth of Egnell Creek, near the junction of the Sheslay and Hackett rivers to the southwestern slope of Level Mountain.
