No. This is a permanent closure. Seine netting that pool would be impossible and is not necessary. Better to let the fish migrate upstream naturally when they are ready.
Apart from the questionable angling methods that seem so prevalent at this particular area, there is perhaps a more compelling reason why fish tend to spend more time than normal in this pool, therefore more susceptible to anglers and why this area should be closed to anglers. This is where Slesse Creek and the Chilliwack River meet. The water chemistry from each system is quite different and could be confusing to these stressed, sexually hormone charged, soon to die but must spawn fish.
DFO’s Cultus Lake Laboratory analysed water samples submitted last September – alkalinity (measured as mg CaCO3/L) in Slesse Creek was nearly twice that of the Chilliwack; 65.4 vs 38.3. pH in Slesse was 7.47, the Chilliwack 7.24.
These are reasonable enough numbers but when suddenly mixed together along with the water effluent (feces, urine, pheromones, hatchery by products, etc) from rearing several million juvenile coho, chinook, and steelhead from the Chilliwack River hatchery that flows into Slesse Creek and is mixed into this soup I think it would be best for these fish to be left alone to, stage.
