The Classification of Tailwater Sites Receiving Residual Flows from Upland Reservoirs in Great Britain, Using Macroinvertebrate Data
The amount of water left in rivers and streams after abstraction for public supply is referred to as the residual or compensation flow. In the past the quantitites of water released from reservoirs have been the subject of arbitrary rulings (Sheail 1984). Throughout Great Britain there are a large number of reservoirs where decisions as to the amount of compensation flow to be released were made many years before the present archive of river flow data was available. These data are now being used by the Institute of Hydrology as the basis for preparing guidelines for resetting reservoir operating policy and compensation releases in order to minimise disturbance to the flow regime downstream and wherever possible to conserve water for supply purposes.
