Fitzsimmons Creek

For half its length of approximately 10 kilometres, the creek courses a U-shaped glacial valley which separates two ski mountains of the Whistler Blackcomb resort, Blackcomb to the north and Whistler to the south.

Issuing onto the relative lowland of the Whistler Valley just adjacent to Whistler Village, the creek turns more northwest, flowing past the White Gold residential area and entering Green Lake just east of Mons.

Fitzsimmons Creek is a very large[clarification needed] and dynamic creek with a history of debris-laden flash floods in times of heavy weather, and is dyked with heavy rip-rap in its source through the area of the village.

A run-of-river hydroelectric plant, completed in 2010, the project temporarily diverts creek water through a penstock 4.5 km downstream, an elevation drop of nearly 250 meters, to a powerhouse generating 7.5 MW of electricity.

The powerhouse is located between the creek and the lowest point of the bobsleigh track built for the 2010 Winter Olympics.
