A study of rainfall and reservoir level data was conducted on the water supply system of South Central Connecticut to investigate the possibility of developing reliable, easy to use drought indicators. Frequency analysis techniques were employed to formulate a model to determine the stage and severity of a drought occurrence on a real time basis. Threshold triggering levels for below average rainfall and reservoir volume were established to identify five stages of a water supply emergency. Water conservation measures corresponding to the identified drought stage were proposed to extend the use of available water until replenishment.
