| Abstract/Description or Keywords | 2013 Annual Report: This Annual Report covers the operations of Corra Linn Dam by the Applicant to the IJC Order (FortisBC) and the associated effects on the water level of Kootenay Lake. FortisBC operates Corra Linn Dam on the Kootenay River approximately 22 kilometres upstream from its confluence with the Columbia River, and downstream from the West Arm of Kootenay Lake. FortisBC controls discharge through and around Corra Linn Dam in accordance with requirements of the Order of the International Joint Commission dated November 11, 1938. FortisBC co-operates with BC Hydro, which also manages a lake level control structure (the Kootenay Canal Project) at the lake’s outlet. Kootenay Lake 2013 Summary: Throughout 2013, FortisBC operated Corra Linn Dam in a manner consistent with that prescribed by the 1938 Kootenay Lake Order. The minimum instantaneous water level was observed at 15:01 PST on April 01, 2013 at elevation 530.10 metres1 (1739.17 feet), reaching elevation 1739.32 feet specified for April 01, 2013 in condition 6 of the 1938 Order. The Board and the Applicant jointly determined the date of the commencement of the spring rise as April 09, 2013. The maximum instantaneous water level for the lake at Queens Bay was subsequently observed at 5:31 PST on June 25, 2013 at elevation 533.20 metres (1749.35 feet). Kootenay Lake discharged 26 cubic kilometres (21.1 million acre-feet) of water in 2013, with an average flow of 824 cubic metres per second (29,100 cubic feet per second). |
