Goolwa Barrage Approaching Goolwa from either north or west, you will find yourself on the Hutchinson Street section of the main road through Goolwa (UBD Map 307, N 7). Turn south on Oliver Street at the corner where there is a petrol station, cross the railway line and then turn left on Barrage Road, just following the curve. Continue along Barrage Road for about 3 km until you reach the gates of the Barrage area and park there (UBD Map 308, G 16).
