Requesting flow data

Flow data from rivers and tributaries is needed for discussions with affected parties. We can supply Mean Annual Low Flow (MALF) and where requested the Mean Annual Flow.

For some tributaries, the data will be based on actual flow sites.

Where there are no flow sites, modelled data can be generated based on the characteristics of the catchment, through a programme called Shiny. 

Where available or necessary, ORC may also be able to provide ‘synthetic’ flows which are modelled on nearby recorded flow data.

To make a request for data complete the online form and list the water takes and the tributary that you are seeking data for.

For any follow-up questions, please call 0800 474 082.
