Reservoir access is site-specific; check the operator’s rules and never enter unless swimming is expressly allowed.

Do not assume a reservoir is open for swimming. Reservoirs are managed sites and may have restrictions, hazards and operational activity. Access to surrounding land does not necessarily mean swimming is allowed.
Check with the operator
Read current signs and the manager’s official information. If swimming is not expressly permitted, do not enter. Where swimming is allowed, follow the site’s designated areas and instructions. Rules and operators differ across England, Scotland, Wales and Northern Ireland; contact the responsible operator if unclear.
