BC Hydro announced that the Site C reservoir which spans 83 kilometers, stretching between Fort St. John and Hudson's Hope finished filling in early November according to sitecproject.com.
The construction of the Site C project commenced in July 2015, and the project is the third dam and hydroelectric generating station constructed on the Peace River in northeastern British Columbia.
The reservoir began to fill on August 25, with the water level rising around 30 centimeters and three meters a day according to BC Hydro.
This new reservoir has a total surface area of approximately 9,330 hectares, including 5,550 hectares of land which has been covered.
Slope stability instrumentation monitoring has been conducted daily, with visual inspections taking place weekly. Changes to the reservoir shoreline and slopes have remained within the anticipated range during the filling process.
Engineers will maintain ongoing monitoring of shoreline and slope stability throughout the operational life of Site C.
The Site C project is on schedule to have all six generating units operational by the fall of 2025, according to a media release on their website. Major project structures, including the earthfill dam, powerhouse, spillways, and approach channel, are functioning effectively.
Site C will generate 1,100 megawatts of capacity and approximately 5,100 gigawatt hours of electricity annually, contributing around eight percent additional supply to British Columbia's electricity grid.
Since the start of reservoir filling, BC Hydro has completed over one thousand inspections and gathered more than one million instrumentation readings to ensure the dam operates safely.
Due to the reservoir’s potential hazards including floating vegetation debris and the stabilization of the surrounding land, BC Hydro has strongly urged the public to stay out of the reservoir area for at least the next year.
To enhance public safety, BC Hydro has placed comprehensive warning and danger signs around the reservoir area.
Cultural monitors from the Treaty 8 First Nations have been overseeing the reservoir filling process across the entire reservoir area since mid-August.
BC Hydro has also established a $20 million fund called the Peace Agricultural Compensation Fund to assist with local agricultural initiatives, programs, and projects.
