River Advice for Boaters (RAB)

(Previously called Strong Stream Advice SSA) is a free messaging service to advise waterway users when levels and flows are changing and we strongly advise against attempting to navigate.

It is available for the Rivers Great Ouse, Nene and Ancholme and is a useful way of making sure rivers are safe to navigate.
