These are warnings about conditions that may affect navigation, such as varying water levels and faster flows.
We provide automated, near real-time data from a number of rivers showing local conditions. The information normally updates every 30 minutes, however please check the time the last reading was taken.
On some waterways we also provide manual information on flood lock and flood gate status. Following flooding it is often necessary to remove silt and other debris before the gates can be reopened, so they may remain closed after river levels have returned 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.
We currently provide warnings for the sites listed, 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, contact the local office for more information or check the Government flood warning information service for the latest river levels.
