top of page was created to offer information on the watershed partnerships and watershed plans that exist on the island of Maui. 

Three watershed partnerships exist on the island of Maui. They include the West Maui Mountains Watershed Partnership, East Maui Watershed Partnership, and the Leeward Haleakalā Watershed Restoration Partnership. Each are voluntary alliances of both public and private landowners committed to the common value of protecting forested watersheds for water recharge, conservation, and other ecosystem services through collaborative management. 

In addition, watershed plans have been created for the West Maui Mountains Watershed and the Southwest Maui Watershed. The Central Maui Soil and Water Conservation District is currently working with the Hawaii Department of Health Clean Water Branch, Maui County, and stakeholders in the community to develop the Maalaea Watershed Plan. As a preliminary step in the Maalaea Watershed Plan, Maui Nui Marine Resource Council has recently completed the Pohakea Stormwater Management Plan. These watershed and stormwater management plans aim to protect sensitive watershed resources and to restore resources that have already been degraded by agriculture or urbanization.

The Southwest Maui Watershed Plan was developed for the Central Maui County Soil and Water Conservation District (CMSWCD) in 2013 to provide sediment reduction measures for the 49,688 acre planning area comprised of the Hapapa, Wailea and Mo’oloa watersheds. The area extends from the summit of Haleakalā to the coastal areas of Kihei, Wailea, and Makena.

The West Maui Ridge to Reef Initiative is an all- encompassing approach across multiple agencies and organizations to address adverse impacts to coral reefs in West Maui. The objective of the initiative is to restore and enhance the health and resiliency of West Maui coral reefs and near-shore waters through the reduction of land-based pollution threats from the summit of Pu`u Kukui to the outer reef. 

The Central Maui Soil and Water Conservation District has begun work on creating the Maalaea Watershed Plan to address land based sources of pollution entering Maalaea Bay and Maalaea Harbor. Working with the Hawaii Department of Health Clean Water Branch, Maui County, the Maui Ocean Center, biologists from Kealia Pond, and stakeholders in the community, the Central Maui Soil and Water Conservation district will design and implement projects to reduce land based pollution entering Maalaea Bay.

The West Maui Mountains Watershed Partnership was created in 1998 and has 10 partners. It covers 48,000 acres and was formed for the long-term protection and preservation of the West Maui Mountains Watershed.

The first Watershed Partnership on Maui, East Maui Watershed Partnership was created in 1991, involves 7 partners and 5 associate partners, and encompasses over 100,000 acres. The landowners of the forested watershed area of East Maui participate together to protect East Maui’s native rainforest and primary water source in perpetuity. They do this to ensure the goods and services of the watershed are provided to the island’s communities and for the continued health of East Maui’s unique native plants and animals.

Leeward Haleakalā Watershed Restoration Partnership (LHWRP) includes 12 partners as well as 10 associate partners. Formed in 2003 and covering 43,000 acres, the goal of LHWRP is to restore koa forests on Haleakalā from Makawao through ‘Ulupalakua to Kaupō between 3,500 and 6,500 feet elevation.
