Cygnet RC Policy & Recommendations

The PLA's Ebb Tide Fluvial Flow Flag Warning system (above) is very similar to the Environment Agency's well established River Conditions system. That system, in place upriver above Teddington Lock, indicates the water conditions between locks using red, yellow and green boards (positioned on the locks). It has long been agreed up-river that: if yellow boards are showing, rowing activity is limited to only the more experienced crews and; that if red boards are showing then, in the interested of safety, no rowing should take place

The system updates automatically twice a day: at 06.00 and 18.00 hrs

The Tideway is larger and therefore better able to cope with increased water volume but a faster stream makes for more difficult navigation conditions. The PLA's system is only for the Tideway (below Teddington Lock) and also applies only on the Ebb Tide

Very low or high flow conditions can mean that the tidal predictions may no longer be accurate, especially if the Thames Barrier is shut. Like at the change of the tide, if in doubt about the direction of flow, position yourself on the starboard side of the channel. Please contact either the Safety Advisor or the captain if you have any questions or require further advice.

BLACK FLAG •Â Lower than average Fluvial Flow

• No restrictions but extra caution should be taken at low tide due to shallower than usual foreshore.

GREEN FLAG •Â Normal Fluvial Flow

YELLOW FLAG •Â Caution, strong Fluvial Flow

•Â Carry a phone, sign-out and make sure that somebody knows you have gone afloat
• Strictly no rowing in the dark on a yellow flag

RED FLAG •Â Extreme Caution, very strong Fluvial Flow

Strictly no outings on the ebb tide, including experienced crews and privateers
