These warnings tell you about conditions that may affect navigation, such as when stretches of river are experiencing variable heights in water level which is most cases will result in faster flows.
Our SCADA system provides near real-time data from a number of rivers showing the local water level conditions. It normally updates every 15 minutes, however please check the time the last reading was taken at each location carefully. River conditions can change rapidly and without warning.
We currently provide automated warnings for a small number of sites, but plan to expand the system in the future. If a site you're interested in is not listed here, please check our stoppage notices or contact the local office for more information.
On some waterways we also provide information on flood lock and floodgate status. Gate status is set manually and is not linked directly to river levels. Following flood events it is often necessary to remove silt and other debris before the gates can be reopened. For this reason flood locks and flood gates may remain closed even though river levels return to normal. Flood locks and floodgates may also remain closed for operational reasons.
Skippers of all craft should always check gate status when planning passage even though river levels have returned to normal.
