RISK ASSESSMENT GUIDE
The table below is intended to assist rowers and coaches in their pre-outing risk assessments. Please be aware that conditions can change in the course of an outing. Also, remember that if you start an outing during the flood tide, you may be out when the tide turns to ebb, presenting very different river flow conditions.
How to use this table.
-
Check the flow rate at Kingston Bridge HERE. The numbers shown in the table refer to this data.
-
Check the tide status HERE: Flood/None/Ebb and read aross for the Risk Score. (Apart from the period 2 hours before and 2 hours after each high tide, Richmond Lock is closed and the river is non-tidal)
-
Then consider wind conditions (speed and direction) (HERE) and visibility. Any score arising from this is added to the river flow risk score
-
See and restrictions that apply to the resulting total risk score from the second table below
Notes:
-
Add the risk score of wind/visibility conditions to the Flow Rate risk score to determine any rowing restrictions. For example, strong wind (2) with 150 m3/s flow rate (2) would give risk score of 4, which would suggest outings restricted to 8s only.
-
Combined risk score of 5 or over = no rowing.
Visibility guide: Eel Pie bridge to the western tip of the island = 180 metres. Eel Pie bridge to the TWRC hard = 100 metres.
