Hahamongna Watershed Park (HWP) consists of approximately 1300-acres of open space that extends from Devil’s Gate Dam north and into the Arroyo Seco Canyon, on the northwestern edge of the city. After many years of planning and community involvement, the Hahamongna Watershed Park Master Plan was adopted to establish a visionary framework for recreation, water resources, flood management, habitat restoration and cultural resources in this area. HWP is managed and maintained by the Department of Public Works, Parks and Natural Resources Division.

In 2005 the city purchased an additional 30 acres of land adjacent to Hahamongna Watershed Park, currently referred to as Hahamongna Annex. This land had previously been owned by the Metropolitan Water District of Southern California (MWD). The land was purchased with the stipulation that future uses of this property must support open space and recreation. With community input, the city has prepared a plan that provides a vision for the future of this property that has now been integrated into the existing Hahamongna Master Plan.  Portions of the site are currently leased to four different tenants, including the Los Angeles County Fire Department and three separate equestrian based organizations.  Learn more about each, below.  

The Hahamongna Watershed Park Master Plan Addendum for the Hahamongna Annex was adopted by the City Council on February 1, 2010.
