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 mighty Atlantic Sturgeon (Acipenser oxyrinchus) have been known to grow up to nearly 4.5 meters long in rare cases. When young, these fish can be confused with the smaller Shortnose Sturgeon, also present in the watershed.As the name suggests, the shape of the head is a key difference in identifying these species. This fish does not have a short nose at all!Unfortunately, Sturgeon are in decline in most of the world. Populations do not rebound quickly due to their long life cycles.#fish #newbrunswick #nature #conservation ... See MoreSee Less

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 American Shad (Alosa sapidissima) is recorded as being present in Maquapit Lake, but is not confirmed to be in other lakes in the watershed.Northern populations of these Shad may survive for multiple spawning seasons, but the fish in more southern populations die after just one.#fish #newbrunswick #nature #conservation ...

That concludes our results from the eDNA testing... but... Who didn’t show up?Several fish not confirmed by our test were included in speculative posts, due to their inclusion in the most recent reports from the Department of Natural Resources and Energy Development.Join us for 11 more Fish Feature Fridays, starring the known fish that were not detected.#fish #newbrunswick #nature #conservation ...
