SEPA Water Level Data

Unfortunately we are unable to publish all our water level stations online at the moment and downloading data is also not currently possible, due to impacts from the cyber-attack on SEPA.

Getting it restored for you is important to us, and we are working hard to make it possible.

Any SEPA flood warnings in force are always displayed here:
