Water Management and Quality

Understanding water quantity and quality is  vital to the health and safety of our community

What is Water Management?

Mississippi Valley Conservation Authority monitors the effect of development and land use to assess watershed conditions. This is done through field monitoring, remote sensing and gathering and interpreting information on the status of water and water related natural resources on an ongoing basis. The careful monitoring of water levels ensures that a flood forecasting and warning service is ever-ready to help municipal officials and the general public take appropriate action in a flood emergency.

Water Control on Mississippi River includes:

  • Water supply
  • Flood protection
  • Recreation and tourism
  • Fish and wildlife habitat


Water Control Structures

  • 30 water control structures on system
  • MVCA owns and maintains 12
  • MVCA operates 7 additional structures under contract with Ontario Power Generation and the Ministry of Natural Resources


Mississippi River Water Management Plan

MVCA works closely with hydro-electric producers, provincial and federal agencies, first nations and other stakeholders to provide coordinated operation of the river system. Read the management plan.

Flood Forecasting and Warning

MVCA is the lead agency for monitoring the potential for local flood threats and to alert emergency response agencies and the public. Through this service, MVCA monitors snow cover, water levels and runoff conditions across the watershed, assesses the risks posed by advancing weather systems on flood prone areas and advises emergency response personnel in the affected areas.

MVCA staff continuously monitor water levels and stream flows while measuring snow pack water content and precipitation. The information is vital for our:


What is Watershed Monitoring?

Watershed monitoring activities have a large impact on the way the watershed is managed, how landowners understand their region, and how MVCA can successfully continue to meet the needs of the natural environment with the needs of the community.

Monitoring helps staff understand the impacts of land use activities (e.g. urbanization) on water quality so that we can make informed decisions about managing and protecting our water resources. Monitoring also helps staff measure the effectiveness of programs and policies that are designed to protect and restore water quality. Education and stewardship activities also rely on monitoring data to understand where work needs to be done and what areas are models of success. The monitoring programs we run are a mix of local initiatives and part of larger provincial datasets.

Water Quality Monitoring is important for us to understand the quality of our lakes ands streams now and identify any trends—good or bad—that effect our precious resource. Water quality monitoring is done through our:


Watershed Report Cards
are published every five years to keep our stakeholders up to date on conditions in the region and help us target  areas for improvement.
