The National Water Commission (NWC) says the Hermitage Dam in St Andrew is showing the effects of reduced rainfall with water levels at the dam now at 42.5 per cent of capacity, down from 48.9 per cent just over a week ago.
NWC made the announcement via social media on Wednesday, urging persons to conserve water as much as possible amid drought conditions affecting the island.
The Meteorological Service earlier this month issued a drought forecast for the island over the next three months, with extreme impact expected in at least three parishes.
The Met Service said its drought forecast map indicates that during the period July to September, there is a high chance of warmer than normal temperatures with below normal rainfall across the island.
It said the current projections indicate a decline in rainfall over most stations, with a possibility that this could lead to worsening drought conditions, especially over sections of Portland, St Catherine and Clarendon.
The Government has meanwhile allocated some $55 million aimed at mitigation efforts.
