Watercourse consents and flood risk legal duties
Watercourse consents and flood risk legal duties refer to the statutory obligations and permissions required for any works affecting rivers, streams, or other watercourses. These legal requirements ensure that developments or alterations do not increase flood risks or harm the environment. Authorities may require formal consent before works proceed, and failure to comply can result in enforcement actions. These duties protect public safety, property, and the natural ecosystem from adverse impacts of water management activities.

❓ Frequently Asked Questions
What is watercourse consent?
Watercourse consent is a legal permission to carry out works on a watercourse (river, stream, ditch, or drainage channel) that could affect its flow or flood risk. In England, the Environment Agency, an Internal Drainage Board (IDB), or the Lead Local Flood Authority (LLFA) handles consents depending on the watercourse type.
When do I need watercourse consent?
Consent is typically needed for dredging, culverting, channel alteration, construction on or across a watercourse, or placing structures or materials within the watercourse or its banks, as these activities can change water flow and flood risk.
What happens if you don’t get consent?
Working on a watercourse without consent can be illegal. Authorities can halt works, require restoration or removal, and you may face enforcement actions or fines if flood risk or the environment is harmed.
What are flood risk legal duties?
The Flood and Water Management Act 2010 assigns duties to lead local flood authorities to assess and manage local flood risk, investigate floods, and share information. Planing authorities and developers must consider flood risk in drainage design (often using SuDS) to avoid increasing flood risk.
Who is responsible for flood risk in development projects?
Responsibilities vary: LLFAs manage local flood risk; planning authorities require drainage plans and SuDS for new development; developers must design and implement drainage to prevent new or worsening flood risk, and property owners maintain private drainage to reduce flood risk.
