The river enters the sea at the city of Bathurst, New Brunswick, on the Bay of Chaleur.  Several falls are present along the river's course, including Indian Falls (near Popple Depot), Nepisiguit Falls and Pabineau Falls.  Along this river lies a vast Forest, where many individuals from the New Brunswick Area set up camps.  There are many lodges set up along the river including Governors Lodge, Rogers Lake Lodge and many others.  These lodges play host to the many individuals taking part in several different outdoor activities including hunting, fishing and snow moiling along the river.  The "Nepisiguit River" is known for its fishing.  Fishing along the Nepisiguit consists of Atlantic Salmon fishing as well as other fishing types including trout.  Hunting is also another activity that takes part along the Nepisiguit due to the widespread animal population and species within this region.  Some of the animals hunted along the Nepisiguit River include moose, deer and partridge.  The Nepisiguit River and surrounding area also have some of the best snowmobiling trails.  During the winter months, individuals from around New Brunswick as well as other parts of Canada come to the Nepisiguit region to take part and join in the vast and widespread snowmobiling community.  Nepisiguit Falls has been developed for hydroelectric power generation.

Currow: Currow (Irish: "An Currach / Corra" , meaning "The Marsh" ) is a rural village in County Kerry in south west Ireland, located approximately 12 km from Killarney and 18 km from Tralee.  Currow is situated on the Brown Flesk River, a tributary of the River Maine.  Currow covers 3,376 Hectares, much of the land is arable, mainly used as pasture for dairy stock.  However, there are areas of peat land, particularly to the south, where a blanket bog is located on the border with Kilcummin.  There are many old, mature trees particularly on the floodplain of the river.  Currow is mainly a residential area with close links to Castleisland.  The main industry is agriculture.  The original village grew up on both sides of the roadway to the north of Flesk Bridge, between two old estates, Dicksgrove and Parkmore, which have influenced the architectural character.  The Meredith Family were the landlords of the area, residing in the old Parkmore estate.  The first influence of the British came from the Herbert Family during the plantations.  The village escaped much of the major development experienced by many nearby villages and towns during the Celtic Tiger.  Any development is mainly one-off housing.  Currow is bordered to the west by Farranfore, to the south by Kilcummin, to the east by Scartaglin and to the north by Castleisland.  Currans lies north west of Currow, which forms the Killeentierna Parish.  Con Houlihan, a columnist with the Sunday World, once wrote how he considered Currow as his 'own favourite' village in Ireland.  Although he is undecided whether Currow is a village or a hamlet.  He also declared he would someday 'apply to be made a Freeman of Currow'.  Currow takes pride in its sporting heritage, producing several international rugby players.  The popularity of the GAA is unrivaled in the community but basketball has thrived in recent decades, particularly with juveniles, with much success at county, provincial and national level.
