Abstract
This paper presents a review of water yields for six reservoir schemes within Selangor and Kuala Lumpur. The study was carried out using up-to-date hydrometric database up to 2009. Three approaches were used for yield calculations; namely, (1) Drought Sequence, (2) Longterm records, and (3) Storage-yield-reliability model techniques/methodologies. It was found that the gross yields of various reservoir schemes were agreeable with one another, at least within the margin of difference which is about 5%.
