Drought conditions have reduced Lower Mainland river levels to the point where Chinook salmon have been unable to cross the sea dam on the Nicomekl River in Surrey, said Nigel Easton, president of the that operates the volunteer-run hatchery in 91原创.

鈥淎ll our fish are sitting at the dam,鈥� Easton told the 91原创 Advance Times on Sunday, Oct. 16, after visiting the dam located near King George Blvd.

鈥淭here鈥檚 a lot of salmon swimming around.鈥�

Because the sea dam has no mechanical gates that can be opened, if water levels aren鈥檛 high enough, salmon can鈥檛 get through. It was slated for an upgrade by the city of Surrey, as part of a flood mitigation program funded by the federal government, but work on a new dam has yet to begin.

While there is concern about water levels, 鈥渋t鈥檚 not a crisis yet,鈥� Easton remarked.

鈥淲e believe as long as the rains come before mid-November, we鈥檒l be okay.鈥�

It will have to be substantial rain, however, enough to raise the river levels.

Environment Canada was forecasting a chance of rain for Friday, Oct 21, and showers on Saturday Oct. 22.
