Reimagine The Arroyo and Upper LA River


Join us to learn more about the Upper Los Angeles River planning effort! This workshop will include interactive exhibits and several exercises where you can share your ideas. Tell us what you want to see along the River and Tributaries, the things you would like to do, and how the River and the Arroyo can continue to be invaluable community assets.

This is a unique opportunity for you to envision the future of the upper LA River and its tributaries, including the Arroyo Seco.

Come dream big!

The River Returns!

It's been so dry in the upper Arroyo Seco Watershed for so long that most people have forgotten the power of the river! The recent storms did a lot to change that! The stream gauge in the Arroyo jumped from 1 cubic foot (cfs) or 7.5 gallons per second to one thousand cfs briefly on January 17 and a week later climbed up to 300 cfs before resting for a bit at 100 cfs. That should really open up the stream up there between Oak Wilde and Switzer's Camp for the fish and aquatic species.

Concerns about HWP raised

Here's the Star-News coverage of community concerns about the recent devastation caused by LA County Flood Control District. It's interesting to note Supervisor Barger's admission about the long-standing neglience of the FCD


Hahamongna Before

Hahamongna Accountability Project Formed

Local residents and community organizations including the Arroyo Seco Foundation have formed a group of watchdogs to ensure that the County Flood Cotrol District fully complies with all their responsibilities in implementation of their Big Dig project.

We need your help again to Save Hahamongna!

How You Can Help

March Is Not Dreary at Hahamongna Nursery

The recent rains have already had a wonderful effect on the plants at Hahamongna Native Plant Nursery. The plants are uncertain about whether it is Spring yet. Some think is is and are blossoming, while others are still relatively dormant.

We are now growing plants for the Berkshire Creek Project in Hahamongna that we are co-sponsoring with the City of Pasadena. We'll be reaching out to the community to make the project a grand example of community involvement and propagate more than 900 plants and many pounds of seeds for the habitat restoration component of the project.
