Po4 Site four (Old Town Drain)

Inactive Physico-Chemical Daly Street, Dalyston

Site located in the middle of the river, directly opposite the old fence found on the upstream side of the old town drain.

Site accessed via kayak from the Daly Bridge, or the Mouth of Powlett Road Bridge.

Land Use

• Rural Grazing

Beef cattle are found on both sides of the river, though the southern side is fenced off and the northern side is not. As a result the southern bank has a much greater cover of riparian vegetation.
