Water Management on the
Kaministiquia River
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

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
