This document investigates environmental impacts of proposed flow changes in River Tavy. The River Tavy had experienced a low flow problem over many years as a result of several major abstractions along its length. Water is abstracted for hydropower generation and public water supplies. Abstraction to the Tavistock/Morwellham canal at Abbey Weir for hydropower represents one of the major abstractions from the Tavy. A Heads of Agreement was signed in 1978 between the then South West Water Authority and the Central Electricity Generating Board with the aim of applying an increasing prescribed flow in the Tavy at the Abbey Weir. There were concerns raised about the lack of flow to users downstream of the tunnel entrance and as a result it is recommended that further trials need to be carried out to establish operating rules to protect Morwellham Combe while maintaining the integrity of the canal.
