It is necessary to have an appropriate licence before work begins on a water impoundment structure - even in the case of an emergency. For more information, see Apply for a water abstraction or impoundment licence. There are certain impoundment activities with low environmental risks or other conditions where exemptions to this rule may apply.
The Environment Agency may take enforcement action against those who do not apply before impounding water. Further details are available from Water management: abstract or impound water
