A watershed is a topographic area where all the water within drains to a common point (ex: Belleisle Bay). The health of a watershed is very important because any impacted or poor quality water will eventually flow downstream to the common point and thus have an impact on it.

The Belleisle Watershed covers approximately 37,000 square Km – from Mercer Settlement to Lower Kars on the Northern side and from Pearsonville to Kingston Corner on the Southern side. The Belleisle Bay itself (approximately 24 square Km) is an offshoot of the Saint John River but also has 20 named tributaries feeding into it. Twelve of these named tributaries have been assessed by the BWC since 2013 (underlined in the list). These stream assessments examine the water quality, fish habitat, and riparian (stream side) health of numerous sites along the watercourse. From these assessments, recommendations for improving the overall health of the watercourse were made and can be found in the yearly ETF reports.
