Residents in the small Riverina communities of Wymah and Granya say they feel "cut off" after the suspension of the ferry service connecting the border towns.

With low water levels in Lake Hume causing the NSW Department of Transport, Roads and Maritime Services to suspend the ferry on Thursday, residents are forced to drive at least an hour to cross over into the other state.

A spokesman said with water levels sitting below 16 per cent of capacity in Lake Hume, the free 150-year-old vehicle ferry could not operate safely between Wymah, in NSW, and Granya, in Victoria.

The ferry was originally built by a pub owner to bring customers over the river to his establishment. It is one of the last cabledrawn ferries in the state and is heritage-listed.
