Water Management
Watershed Planning & Development

Water is a fundamental part of life - we simply can't live without it. In Ontario's near north, we are fortunate to be surrounded by clean lakes and rivers. The North Bay - Mattawa Conservation Authority (NBMCA) recognizes the recreational, social and economic value clean water brings to our community.

In addition to the flood and septic program, the NBMCA is actively involved in the protection of our water resources through the Drinking Water Source Protection initiative and the Provincial Groundwater Monitoring Network.  

Provincial Groundwater Monitoring Network

Groundwater is a valuable resource upon which three million people in Ontario depend.   Accurate data on the state of groundwater resources does not currently exist in the Province of Ontario.  The purpose of the Groundwater Monitoring Network is to determine where, why and how this resource is affected by such issues as the changing climate and competing demands.  

The NBMCA is one of 25 conservation authorities in the Province of Ontario to enter into a six year partnership agreement with the Ministry of Environment.  The intent of the agreement is to design, implement and operate a Groundwater Monitoring Network program within the North Bay-Mattawa Conservation Authority's watershed. Once a year, the NBMCA will collect water samples from specific test wells and undertake local level data analysis and reporting. 

An accurate assessment of current and emerging trends affecting Ontario's groundwater will allow for the development of science-based policy and groundwater management programs.  Local municipalities will also be provided with  accurate data from which to make informed land-use planning decisions and to develop sustainable water management strategies.

Preliminary Groundwater Study


In 2003, the North Bay-Mattawa Conservation Authority, with funding from the Ministry of the Environment, conducted a local groundwater study.  The study consisted of a groundwater aquifer mapping component as well as a well-head protection component for the Town of Mattawa and the Municipality of Powassan.  The final report was approved in January 2006 and copies are available at the municipal offices and at the NBMCA office in North Bay.

The information gathered through both the groundwater study and the current groundwater monitoring program will be included in the watershed characterization report and ultimately, the development of the local Drinking Water Source Protection plan.
