At Tidnish Bridge, the river flows the final 2 kilometres in a serpentine manner to discharge into the Northumberland Strait at Jacksons Point on Baie Verte.

This section of the river downstream from Tidnish Bridge also forms part of the interprovincial boundary with New Brunswick.

The river is carefully navigable in its upper reaches past the Chignetco bridge during high tides.

The mouth of the river supports a smelt fishery, although this activity has been in slow decline.

These are set from rafts or, in winter, from holes cut in the ice and allowed to "strain" the tide to catch smelt.
