What is a watershed?
A watershed is a topographically defined area of land where the water drains to a common point. In our watersheds, this common point is usually the Chaleur Bay. In a watershed, surface water and groundwater are generally connected since water flows horizontally through the rivers and vertically through the different soil layers and the substrate.
This movement of water through a given territory connects hydrological zones. Any activity that affects the water quality, quantity or flow in part of the watershed can affect downstream sites. It is important to understand the connectivity in a watershed when planning or managing activities related to water quality.
