During dry seasons, we publish weekly information on river flows here.
River flow data
The graph below shows recent River Test flow data during Spring/Summer 2019 (source: The Environment Agency):
We work closely with the Environment Agency (EA) and local environmental groups to balance the needs of our customers with those of the natural world.
This includes monitoring river flows – especially during dry spells, when water restrictions may be necessary to protect the health of these natural habitats.
If flows drop below:
- the 60 day trigger, we begin drought permit pre-application
- the 35 day trigger, we apply for a drought permit
- the 'hands-off' flow, we're not allowed to take water from the river without a drought permit
Daily river flows
The EA monitors UK rivers and publishes daily river flow data on its website. To see the latest updates about a river near you, visit the EA's Hydrometic Data page and click on the rivers represented by a red dot:

Protecting Hampshire's rivers
During 2019, new rules were introduced to protect the Rivers Test and Itchen by controlling when we could take water for our customers. As a result, Hampshire faces an increased risk of drought during dry weather.
Find out how we're keeping customers' taps flowing while protecting Hampshire's rivers.
