The London police have issued a boating ban on all local waterways.

The ban comes after the Upper Thames River Conservation Authority notified police theban threshold on the Thames River had been met.

Police and the conservation authority both warn the public to exercise caution and stay off all bodies of water.

The UTRCA says water levels will remain elevated throughout the weekend.

Flood prone ares such as low-lying flood plains may become inundated, it says.
