Water Management on the Kaministiquia River

slide-17
SLIDE 17

17

  • 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

slide-18
SLIDE 18

Water Management Plan (WMP)

18

  • 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

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
