The LowFlows Estimation Service is a cost-effective alternative to buying our software to get river flow estimates. The service provides both monthly and annual mean flows and flow duration statistics.

Most UK river catchments are ungauged and the highest demand for river flow estimates is in these catchments. The LowFlows Estimation Service is for anyone who’d like an alternative to buying LowFlows 2 to get the information that’s needed.
