Fisheries Enhancement Options for Dinosaur Lake, A Review R. Pattenden and G. Ash April 1993 PWFWCP Report No. 72 The Peace/Williston Fish & Wildlife Compensation Program is a cooperative venture of BC Hydro and the provincial fish and wildlife management agencies, supported by funding from BC Hydro. The Program was established to enhance and protect fish and wildlife resources affected by the construction of the W.A.C. Bennett and Peace Canyon dams on the Peace River, and the subsequent creation of the Williston and Dinosaur Reservoirs.

EXECUTIVE SUMMARY Dinosaur Lake is a "run-of-the-river" reservoir which has a steep bottom topography and short water retention period. As such, reservoir productivity is low and the littoral zone is severely limited. Only two tributaries, Johnson and Gething creeks, provide spawning and rearing habitat for fish populations in Dinosaur Lake. Due to poor quality habitat and variable flow regimes, recruitment of sportfish from these systems is low. Entrainment of fish out of Dinosaur Lake, via the Peace Canyon Dam, likely is a significant factor which restricts fish abundance in the reservoir.
