The Nerepis River is a river approximately 25 miles (40 km) long in New Brunswick, Canada. A popular river for canoeists and anglers, it is a tributary of the Saint John River. The river has been subjected to significant environmental stress over many years.
The river meets the Saint John River at Westfield, part of the Town of Grand Bay-Westfield, where it feeds a fresh water marsh. Towards the headwaters, it passes through the communities of Nerepis, Blagdon, Bayard, Welsford (where a tributary, Douglas Creek, tumbles into the river over a 15-metre (49 ft) waterfall),[1] Fowlers Corners, Petersville, and New Jerusalem. The river also passes the 13th hole of the Welsford Golf Course.[2] Most of the land it passes through is undeveloped although there has been extensive clear cutting in the upper reaches. The Nerepis River Watershed also drains part of CFB Gagetown.
