The new millennium brought droughts, increasing pressure on the {{okina}}Īao [[aquifer]], with withdrawals rising above 18 million U.S. gallons (68,000 m<sup>3</sup>) per day. Recent estimates indicate that Maui has a potential supply of potable water around 476 million U.S. gallons (1,800,000 m<sup>3</sup>) per day, {{Citation needed|date=June 2017}} virtually all of which drains into the ocean.

Water for agriculture comes mostly from East Maui streams, routed through a network of tunnels and ditches dug by [[Chinese immigration to Hawaii|Chinese]] laborers in the 19th century.
