|Stevens Creek provides high value fish habitat for kokanee, rainbow trout, mountain whitefish and bull trout. As well, Whatshan Lake is a popular recreational fishing lake. |
The original structure was proposed by Ingersol Mountain Enterprises Ltd. in a report dated June 1, 2002. The works was finally completed during the fisheries window from July 15 - August 31, 2004. The report recommends that 15% of the stones be a minimum diameter of 66cm. Upon a quick review of expected stream velocities this sizing seems reasonable based on the Q100 flows of 16.8 m3/sec provided by Dave Grant, P. Eng. in 2004.
The following reports provided additional information:
