The East Maui Watershed Partnership (EMWP) is an environmental effort between federal, state and private landowners to preserve the native forest.  We and our partners want to ensure that Maui's residents have a clean source of water for domestic, commercial and agricultural uses for this and future generations. 

The East Maui watershed contains some of the most important natural resources in the state of Hawai`i. The watershed is the largest single source of surface water, with an average harvested flow of 60 billion gallons [227 billion liters] per year. Forty-eight streams originate from the watershed; 35 of them are perennial and 13 are intermittent. Maui County estimates that total water use will increase from approximately 170 million gallons per day (MGD) [644 million liters per day] in 1987 to 186 MGD [704 million liters per day] by the year 2010. The total potential water from the East Maui watershed is estimated at 489 MGD [1.8 billion liters per day], or 179 billion gallons [678 billion liters] per year!
