Continuing on into the Team Valley, the river flows through a culvert in the middle of the roundabout underneath the A1 road, it then continues through the Team Valley Trading Estate through a covered culvert, before emerging to the surface halfway along.

It then flows through the site of the 1990 National Garden Festival, before finally discharging into the River Tyne in Dunston.

The Environment Agency measure water quality of the river systems in England.

Each is given an overall ecological status, which may be one of five levels: high, good, moderate, poor and bad.

There are several components that are used to determine this, including biological status, which looks at the quantity and varieties of invertebrates, angiosperms and fish.
