Lower Kennebecasis Watershed
Low gradient flow creates many oxbows and turns in the Lower Kennebecasis as it flows past Sussex, through Apohaqui and Norton, and finally to the salt water influences near Bloomfield Bridge. The largest influence on this Lower sub-watershed would be Moosehorn Brook, the biggest tributary below the confluence of the Millstream River in Apohaqui. Many of the tributaries are modestly healthy, but the lowland areas are heavily impacted by the historical agriculture practices. The riparian areas are the most impacted component of the system and thus bank erosion and stream temperatures are the prevalent issues within this Lower Kennebecasis sub-watershed.
The land use of Lower Kennebecasis River is as follows:
- 77% Forestry
- 15% Agriculture
- 5% Occupied
- 3% Water/wetlands
There are 7 main tributaries that feed the Lower Kennebecasis River. The Musquash and Moosehorn systems drain the northwest side of Vinegar Hill while virtually wrapping around Thompson and Clements Brooks. All four of these tributaries flow into the south side of the Kennebecasis River. Almshouse and Bloomfield Brook are the only large tributaries draining the north side of the Lower Kennebecasis and this is due in large part to the Millstream River draining a good portion of the north bank. The elevations of this sub-watershed typically are no more than 200m (660’), but the ridges that create Vinegar Hill reach over 350m (1155’) and Bloomfield Ridge is just over 300m (990’).
