Who enforces compensation flow requirements for reservoirs?

The Environment Agency regulates and monitors compliance with compensation flow requirements. They can issue fines and enforcement orders if water companies fail to maintain adequate flows, and the penalties can be substantial, especially for repeated violations or environmental harm.

Where is Chelburn Reservoir?

It's on the east Lancashire moors near Littleborough in the Metropolitan Borough of Rochdale, Greater Manchester. The reservoir was originally built in 1799–1801 to supply water to the Rochdale Canal and is now operated by United Utilities.

Can I find out the specific compensation flow requirements for a particular reservoir?

In theory, yes—the details are in the abstraction license granted by the Environment Agency, which is a public document. In practice, tracking down the exact terms for a specific reservoir often requires submitting formal information requests or digging through planning and licensing documents, as the operational details aren't usually easy to find online.
