16 • Prior to 1990 - Ontario Hydro voluntarily managed water flows and levels for power generation as well as to accommodate other user interest groups
• 1990 - Kaministiquia Water Management Study provided recommendations for the operation of the river system
• 2002 - An amendment to the Lakes & Rivers Improvement Act (LRIA) requires all owners of water power facilities in Ontario to prepare a WMP
17 Water Management Plan (WMP)
• Required by the OMNR – ‘New Business Relationship’ with hydropower industry – Amendments to the Lakes & Rivers Improvement Act (2002)
• The Goal: Support sustainable development of water resources for water power and other uses, while protecting and enhancing the natural ecosystems
• Identifies water flow and level compliance requirements – Waterpower facilities (generating stations) – Control structures (dams)
• Developed through a formal planning process
18 The Kaministiquia River System WMP • Finalized in June of 2005 • Valid for a 10 year period – July 1st, 2005 – March 31st, 2015 • Planning process involved – Proponents (OPG & OMNR) – Regulator (OMNR) – Public Advisory Committee (PAC) & First Nations • Friends of the Kam • AbitibiBowater Pulp & Paper Canada • Fort William Historical Park • Dog Lake Campers’ Association • Northwestern Ontario Prospectors Association • Municipality of Conmee • Thunder Bay Soil & Crop Improvement Association • Municipality of Oliver-Paipoonge • Northwestern Ontario Sportsman’s Alliance • Shebandowan Lake Advisory Committee • Lakehead University – Wetland & Environment
19 The Kaministiquia River System WMP • SAC Members – Dog Lake Camper’s Association – Shebandowan Lake Campers Association (also represent Kashabowie) – Lakehead Region Conservation Authority – Resolute Forest Products – Fort William Historical Park – Friends of the Kam – Municipality of Oliver Paipoonge – Upper Kam Residents
OPG and OMNR are committee resources
• Reports (2) – Annual compliance report and letter report immediately following an out of compliance condition – Annual summary report of the watershed

33 Lower Kaministiquia River Lake Sturgeon Flow Requirements • In 2002-05 WMP discussions – flow requirement for lake Sturgeon was a major issue • 2005-2013 MNR/OPG studies • 2014 Instituted during May 5 – July 1 – 25 cms minimum total river flow after May 5th (upstream migration from lower river) – 14 cms minimum spill over falls May 15* – June 27 (spawning and drift) – 3cms/day spill rampdown June 27 – July1
*May 15 or when KB TW temp reaches 11C
§ Original Dam built in 1923, replaced in 1956 § Existing dam is safe and operable, but showing signs of deterioration consistent with end of life § Studies determined the preferred alternative is to replace the dam (vs rehab, removal or do-nothing) § New dam will be a concrete structure similar is size and flow capacity § Plan is to award contract Fall 2015, then construction during the summers of 2016 and 2017 OPG’s WEBSITE for Water Levels and Flows http://www.opg.com/generating-power/hydro/northwest-ontario/river-systems/Pages/kaministiquia-river.aspx Questions…..
