The City of Mercer Island reported on July 10, 2024, that the local water reservoirs have recovered to adequate levels thanks to the community's collective efforts in significantly reducing water consumption. Officials thanked residents for their diligence during a recent period of unprecedented water demand, which had strained the city’s water supply. Despite the positive recovery, the city continues to operate on a backup supply line and urges residents to remain vigilant in conserving water. Guidelines for voluntary water conservation have been introduced, advising residents to water plants no more than three times a week and to limit shower times. The city emphasizes that if water use surges again, emergency restrictions may need to be reinstated.

City staff are actively monitoring reservoir levels and water usage, providing updates through various channels. Residents can also check the city’s Water Usage Dashboard for real-time statistics. This proactive approach aims to ensure a sustainable water supply for the community moving forward.
