About Us

Welcome to the Jemseg Grand Lake Watershed Association.  We are a committed group of volunteers working to create and maintain a healthy watershed for all, while fostering a culture of shared responsibility and stewardship of this wonderful resource.  Our watershed covers 3,950 square kilometres, and is home to Grand Lake, the largest freshwater lake in the Maritimes (171 square km).

The above image shows our watershed in green, outlined in red, as defined by the New Brunswick Hydrographic Network.  Grand Lake is the largest body of water in the watershed, located in the southeast corner of the green watershed area (blue shaded area).  The Jemseg Grand Lake Watershed encompasses all lakes, streams, rivers, and other water bodies whose water eventually flows into the Jemseg River.  The Watershed is centrally located in New Brunswick, very near the capital city of Fredericton.  Jemseg is a community at the head of the Jemseg River through which all water exiting our watershed flows into the Wəlastəkw (Saint John River).

We are a committed group of volunteers who care about the Jemseg Grand Lake Watershed ecosystem.  The natural beauty, history, water activities and unique flora, fauna and wetlands of our watershed have attracted generations of summer and permanent residents, starting with the First Nations Wəlastəkwewiyik, people of the Wəlastəkw (Saint John River).  Wəlastəkw is the Maliseet name meaning “beautiful river”.

Let’s meet a new fish each Friday! This fish was included in the Department of Natural Resources and Energy Development August 2022 Report for at least one of our lakes.The Slimy Sculpin (Cottus cognatus) is a nocturnal fish that has an easy time hiding on the bottom due to its camouflage and lack of a swim bladder. Its lesser buoyancy gives it the appearance of hopping along when it swims. While it has lookalikes elsewhere, this fish should be easily identifiable in our watershed.Their sensitivity to acidification gives them use as an indicator species.#fish #newbrunswick #nature #conservation ...
