Water Quality Starts at the Source (Loch Garry 2011)

Our Start:

  • 35 concerned citizens approached the Region Conservation Authority (RRCA) in the summer of 2011 to gain a better understanding of lake management issues
  • Formed in Fall 2011 to seek methods of controlling the EURASIAN MILFOIL in Loch Garry and the Loch Garry lake system
  • Target 200 plus members

Our Research Workshop October 19, 2011

  • Water Level Management - History & hydrology of Loch Garry (Roger Houde/Philip Barnes RRCA)
  • Eurasian milfoil and Invasive Species – prevention and control of invasive species (Matt Smith, Ontario Federation of Anglers and Hunters)
  • Loch Garry Fish Community – recent sampling and factors influencing fish kills (Anne Bendig, MNR)
  • Healthy Shorelines – Best management practices for shoreline landowners (Norm Genier, RRCA)
  • Charleston Lake example – Healthy lake planning (Bill Hallam, Charleston Lake Association)

Our Objective:
To improve the quality of the Loch Garry lake system including:

  • Improving the water quality resulting in:
    •  Return to normal and life-sustaining oxygen levels
    •  Decreased temperature stratification
    •  Improved odour and taste
    •  Reduced Disinfection By-Products (water treatment)
  • Natural recovery of fishing stock
  • Return to past levels of swimming, fishing and boating

Our Approach:

  • LGLA supports a broad-reaching solution to benefit the Loch Garry lake system including the residents of Alexandria
  • LGLA supports a long-term, effective and cost-efficient solution
  • LGLA desires to partner with the Township of North Glengarry to facilitate the solution

The Deterioration is not recent

  • Loch Garry is: Eutrophic, suffering serious oxygen depletion and rapidly congesting with Eurasian Milfoil. (Dany Boudrias Aquatic Ecologist 2006)**

Effects of Eutrophication on Water Users:

  • Complaints about taste and odour
  • Risk of exposure to potentially toxic organic compounds
  • Higher water treatment costs
  • Increased plumbing costs
  • Diminishes lake holding capacity caused by weed decay

Potential solutions are limited:
Mechanical harvesting and herbicides provide short-term control with high economic costs and negative impacts to non-target biota and ecosystems (Newman, R.M. 2004)*

  • Harvesting typically increases milfoil growth due to the cut pieces that remain in the water that re-root
  • Harvesting and water turbines can be more than $100K
  • The use of herbicides, especially in the case of Loch Garry, Middle Lake and Mill Pond could result in an important algae bloom. (Dany Boudrias Aquatic Ecologist 2006)**

Potential Biologic Control Agents:

  • The native milfoil weevil is the most extensively researched species and has been used to inoculate milfoil beds throughout the US and recently Ontario and Quebec (Newman, R.M. 2004)
  • Milfoil Solution Inc., a Canadian Subsidiary of EnviroScience Inc. has successfully introduced weevils to several lakes in the US and Ontario

Satisfied Customers:

  • Cedarville Bay, MI  |  15,500 Weevils 2007-2008
  • Puslinch Lake, ON  |  48,500 Weevils 2006-2008
  • Sawyer Lake, MI  |  81,000 Weevils 2003-2005
  • Lake Bonaparte, NY  |  214,600 Weevils 2002-2008
  • Bass Lake, MI  |  37,000 Weevils 2001-2003
  • Van Etten Lake, MI  |  130,000 Weevils 2000-2002
  • Lake St. Helen, MI  |  78,000 Weevils  1998-2002

Project Plan:

  • LGLA recommends the use of weevils to control and potentially eliminate milfoil
  • In accordance with the goal to improve overall water quality, weevils to be distributed in both Loch Garry (40,000) and Mill Pond (10,000)

Project Costs:

  • First year: $50,950.00 +HST
  • Four year range: $144,000-$162,040 +HST

Our Recommendation:

  • Township contracts Milfoil Solution Inc. to proceed in 2012 with 50,000 weevils.
  • LGLA will use best efforts to raise a minimum $40,000 over four years by grants, individual and corporate donations.
  • All money raised will be donated directly to a Township account to qualify for donor tax receipts.

Potential Donors:

  • LGLA members
  • Trillium
  • Scotiabank
  • RBC Clean Water Program
  • Muskie Canada
  • Ducks Unlimited
  • Ontario Federation of Anglers and Hunters
  • Individual and Corporate donation drive including residents of Alexandria

Benefits for Town of Alexandria:

  • Better water quality
  • Potential reduction in water treatment costs
  • Increase in property values 
  • Increase in tourism
  • Return of aquatic activities 

Benefits for Township: 

Shoreline residents:

  • Return of aquatic activities
  • Increase in property value at resale


  • Survival and reproduction of sensitive fish species
  • Increase in wildlife habitats that milfoil has destroyed
  • Increase in natural vegetation

Township must act quickly to protect:

  • The source of potable water for the Town of Alexandria
  • The only in-land lake system in Ontario east of Ottawa
  • Land values in Alexandria and the Township
  • Their most important asset
