Announcing the 30th Anniversary of
Hahamongna Watershed Park

2023 is the thirtieth anniversary of the founding of Hahamongna Watershed Park. It was an important milestone in the history of Pasadena and particularly its management of the Arroyo Seco. The city renamed the former County Oak Grove Park to show respect for our indigenous precedessors and to send a signal to all about the importance of water and sustainable management of natural resources.

The Arroyo Seco Foundation will hold a series of events and activities during this year. You can help shape the celebration with your suggestions by taking this survey.

ASF is working together with the renown California Art Club to present The Great Hahamongna PaintOut and Walkabout on Saturday, March 18 in Hahamongna Watershed Park. This is the first event celebrating HWP’s 30th anniversary, and it promises to be an exciting, education and entertaining event. Painters and sculptors will spread though the park capturing the beauty of Hahamongna and the majestic San Gabriel Mountains. Environmental and public agencies will host learning stations featuring some of the key issues that affect our region: water scarcity and conservation, climate change impacts, the birds and wildlife of Hahamongna and much, much more. Attendees will be able to walk about and explore our region’s most important treasure in guided tours. And musicians will enliven the scene with acoustic entertainment.

Minigolf Doesn’t Belong in the Arroyo

The Rose Bowl Operating Company seems to have lost its sense of place. They’re trying to slip a new miniature golf course and an expanded driving range into Brookside Golf Course in the Arroyo Sect. And they are hoping that you don’t notice.

Climate Resilience Environmental Education @hahamongna

Four leading local environmental organizations -- Pasadena Audubon, Outward Bound Adventures, Arlington Gardens, and the Arroyo Seco Foundation -- are now working together to develop a dynamic environmental education center in eight old Forest Service Buildings in Hahamonga.

Be on the lookout for the Pasadena City Council to issue the official request for proposals to start the selecion process, perhaps even before the end of this month.
