Excerpt from Wikipedia

The Jordan River Dam, officially the Jordan River Diversion Dam, and known locally simply as Diversion Dam, is a dam located in Jordan River, British Columbia, Canada. It is part of the second hydroelectric development on Vancouver Island.

History

Prior to the dam's construction, the Lubbe Powerhouse was the main source of electricity to Victoria. Upon completion, it dwarfed the previous plant.

The Vancouver Island Power Company, a subsidiary of British Columbia Electric Railway, completed construction of the smaller Bear Creek Dam and the main Jordan River Diversion Dam in 1911. At 126 feet (38.4 metres) from top to bottom, the Diversion Dam was upon its construction, the highest dam in Canada. Water flowed through a long flume to the penstock above the power house. From 1912 to 1931 continual improvements and additional generators pushed the capacity of the power house to 26 megawatts.

In 1971 the flume was replaced by a 7 km tunnel, with a penstock flowing down to a new power house, located across the river from the original. A Japanese built generator replaced the old equipment, boosting power output from 26 megawatts to 175 megawatts.

Current operation

Water collected at Bear Creek Dam and Diversion Dam, is then used to fill Jack Elliott equalization reservoir on demand and flows from there through a 8.8 km (5.5 mi) long tunnel into a steel penstock for the last 330 feet (101 metres) of vertical height. It provides 35% of Vancouver Island's generating capacity.

In 1996, the provincial government initiated a Water Use Planning (WUP) program, demanding that BC's water licence holders show they can manage the potential environmental impact of reservoirs. in 2001 the Jordan River "WUP" was underway, with restoration of fish habitat a top issue.

A 2014 BC Hydro study indicated Jordan River had a high risk of seismic dam failure. BC Hydro has offered to purchase the nine residences in the evacuation zone.
