The Tuapeka Mouth ferry is back on the Clutha River after being out of action since mid-January because of flood damage to its ramp.
The 115-year old ferry carries vehicles and passengers across the Clutha near the township of Tuapeka Mouth.
It's believed to be the last current-driven public ferry operating in the southern hemisphere.
Its owner, the Clutha District Council, said the first crossing would be at 4pm.
