The river runs from Broadbury through the valley below Germansweek and empties into Roadford Lake, a man-made reservoir built in 1989.

In July 2006 some 100 million litres of water were released from the lake to help the survival of salmon in the river during a prolonged period of drought.

[2] After Roadford Lake the river continues through Slew Woods below the village of Broadwoodwidger.

The United Kingdom's environmental organisation Natural England currently runs a grant scheme called Catchment-sensitive farming.

The River Wolf is included within one of the priority catchments targeted in this scheme [3]
