The experimental drought assessment of the U.S. Drought Monitor indicates that some locations in the Republic of Palau had increased to exceptional drought conditions (Drought level 4). The main islands of Palau did however see increased rainfall with two 2 day periods experiencing heavy rainfall.

The Ngerimel Reservoir has been shut down and the Ngerikill River is the only remaining source of public water in the State of Koror.

As the drought has persisted for months the water supply has suffered in the Republic|and water rationing was implemented. Earlier in the month the severity of the drought necessitated water only being on for only up to 2 hours per day. The rainfall|during the later part of the month helped alleviate the situation and allowed a relaxing of the water rationing increasing the on time for water to 8 hours.

Schools in Palau have cut hours because of the inability to provide water to students. |Some restaurants have reduced working hours because of the lack of water, while some have shifted to using paper cups, plates and plastic utensils to save water that might have been used to wash dishes and utensils. Hotels are also suffering from the water shortage as some bookings have been cancelled.
