A comparison is made between pre‐ and post‐drainage scheme river flows recorded on the River Maine, Co. Antrim. A method of using five‐year reference periods has been applied to the mean daily flows to smooth and eliminate, as far as possible, variations due to climatic changes. Any loss of energy production which might have been due to changes in river flow was examined for turbine installations at a factory at Cullybackey. The quantities of usable water, and hence potential energy production, were calculated for each of the post‐scheme five‐year periods and compared with a pre‐scheme five‐year reference period. Any potential loss was then represented by a depreciation factor. It was found that no measurable loss of potential energy production has occurred on the River Maine in the post‐scheme period.
