Hundreds of attempts for every successful passage up the spillway into Vaseux Lake. An unbelievable amount of fish hit the cement abutment on the right side and made a large splat. Sometimes you expect to see them belly side up after hitting so hard but so far haven't seen any casualties. I read that 670,000 sockeye entered the Columbia River with the majority destined for this area of southern BC. One can hope they successfully spawn to further increase the population.
