Freshwater Mussels

2018 was the first year of the Petitcodiac Watershed Alliance Freshwater Mussels program, to assess the populations of various mussel species found in the Petitcodiac watershed. It has been almost two decades since a survey was completed in the region to monitor the change in population of local freshwater mussel species, and we hope to find thriving biodiverse habitats.

Green Infrastructure

After a brief hiatus, Green Infrastructure (GI) projects were restored at the PWA in 2018 to help the local communities of the Petitcodiac & Memramcook watersheds to adapt to climate change impacts through the use of natural and nature-based infrastructure and rainwater harvesting. Through expanding GI in this region, the PWA seeks to reduce pollution and urban stormwater run-off from negatively impacting urban streams and habitats.

Water Quality Monitoring

Every year, the Petitcodiac Watershed Alliance monitors water quality throughout the Petitcodiac & Memramcook River watersheds. Historical data was analyzed starting in 2018, providing a longer term picture of the health of the watersheds.

Culvert Assessment Program

The Broken Brooks project is in its eighth year assessing culverts for fish passage in the Petitcodiac and Memramcook River watersheds. A broken or insufficiently designed culvert can act as a barrier to several kilometres of upstream fish habitat, reducing reproductive success.

Wood Turtle Monitoring Project

We undertook the first-ever formal study of Wood Turtles in the Petitcodiac River watershed. This species is in decline due strictly to human activity and development, and before this study, its population status within our watershed was unknown.

Pollett River Assessment

The Pollett River is a river that is located between the village of Elgin and Salisbury. This watercourse has a watershed area of 314 km2. Almost 50% of the area in this watershed is made up of woodlots. A large percentage of forest is still intact, and this watershed has a number of unique features.

Jonathan Creek Environmental Monitoring

The Petitcodiac Watershed Alliance (PWA) in partnership with the City of Moncton and the Jonathan Creek Committee, have been working to restore the Ryan Rd branch of Jonathan Creek. Restoration efforts will include the repair and re-sloping of severely eroding banks, and restoration of the buffer zone along a 750m section of the branch.
