The work window on Queen Charlotte's Stanley Lake weir will remain open for a little bit longer.Queen Charlotte administrator Bill Beamish said the Fisheries and Oceans Canada and the Ministry of the Environment both agreed to extend the fish window from September 15 to September 30.The work has been challenging for the contractor due to heavy rain, said Mr. Beamish. With the level of the lake raised beyond the high water mark, it is difficult to access the work site until the water has drained. The weir, a metal structure at the outflow of the lake, is designed to hold the water at the high level mark. The plan is to hold the water back so that during low rainfall periods, the water level in the Honna River can be maintained for Queen Charlotte's water supply.The contract for the weir system was let in June to Dan Kendall and Sons. The weir is made of thick sheets of corrugated metal driven into the ground. While the contractor is working, a net has been installed across the lake mouth to keep fish from getting washed into the worksite. As well a temporary berm has been installed.Mr. Beamish said the original fish window was open from June 15 to August 15. The weir is part of Queen Charlotte's $4 million water system, which included an intake on the Honna River and a new treatment plant.
