Emergency Measures Proceed

County crews have now completed the emergency measures at Devil's Gate Dam.

Nearly 200 people joined Hahamongna Walkabout on Saturday, March 5th for a fun and informative trek about the Hahamongna basein. After a brief overview, participants stopped at learning stations that filled them in on the habitat, wildlife, bird, and water riches of the area.

Thanks to all the volunteers who made this event such a success.

The Los Angeles County Supervisors on Tuesday, March 1st approved a motion instructing the County Department of Public Works to conduct a full environmental impact report on the sediment management program at Devil's Gate Dam and Hahamongna in the Arroyo Seco.

This victory is the first step in ensuring that Hahamongna and its nature as well as the local neighborhoods are protected. A very important step in the right direction!
