Watershed monitoring helps us:

  • to identify issues, project future conditions,
  • focus natural resource management actions where they are needed most, and
  • track progress over time. 

A clean and plentiful water supply is one of our most important natural resources. As our population grows and development intensifies, the challenge to maintain high quality and sustainable quantities of water will increase in scope and complexity.

Regular reporting can assist with targeting rehabilitation and protection programs, improving accountability to the public, municipalities and other stakeholders, as well as supporting some of the broader reporting requirements of provincial and federal governments.

Monitoring conditions helps to inform local watershed plans and programs.
