Strong Stream Advice (SSA)
The Rivers Nene and Great Ouse are unique in the Region because the the Environment Agency 'reverse the locks': an operation which closes the affected locks to navigation. 'Strong Stream Advice' procedure advises boat users that locks are 'reversed' and that the Agency strongly advises against attempting to navigate. SSA also operates on the River Ancholme to indicate river level changes to users especially at South Ferriby when the sluices are in operation. The procedure involves an automated phone call being made to a predetermined set of telephone numbers when the rivers reach certain levels or flows. The telephone numbers belong to boat clubs, marinas and others on the River Nene, Great Ouse and Ancholme navigations.
River users are also able to telephone the Agency's Floodline Information Service to hear a recorded message which will inform users whether Strong Stream Advice is on or off. To do this complete the following steps:
- Call Floodline, the number is - 0845 9881188 - You will be welcomed to Floodline and offered different touch tone options
- Choose option '1' by dialling '1' on your phone to 'listen to pre-recorded information for flood warnings currently in force'
- Then simply enter one of the following quick dial SSA numbers:
- River Nene 032112
- River Great Ouse 033211
- River Ancholme 031212
