The Arroyo Seco Foundation (ASF), in cooperation with the Los Angeles Flood Control District and Pasadena City Council, has secured a $3.3 million State grant to improve water reliability and environmental conditions in the Hahamongna watershed area. The grant comes from the California Department of Water Resources as part of Proposition 84, which was approved by California voters in 2006. “We are pleased that we’ve been able to win this funding for Hahamongna and to work in partnership with Pasadena on a project that is a model of environmental stewardship and community involvement,” says Tim Brick, managing director of the Arroyo Seco Foundation. “The project, he adds, “will save innumerable fish in the Arroyo stream and millions of dollars for Pasadena ratepayers.”

The grant will enable the ASF to:

  • Upgrade the Arroyo Seco water intake structure to capture Pasadena’s full water rights

  • Evaluate the potential advantages of an inflatable dam

  • 
  • Improve recreational opportunities for local residents by installing a restroom, interpretive signage, picnic tables, a water fountain and a horse trough

  • 
  • Restore riparian habitat in the Arroyo Seco stream by removing unused facilities, planting native plants, improving fish conditions and removing invasive species



The water intake structure, in this photo, was designed to divert 25 pubic feet of water per second (cfs) to help the City reduce its reliance on imported water from the State Water Project and the Colorado River. Storm damage following the 2009 Station Fire reduced the amount the City is able to divert to 18 cfs. In addition, a similar structure on a stream running through Millard Canyon, a tributary to the Arroyo Seco, was completely destroyed by the storms. The Lincoln Avenue Water Company, as a result, is currently unable to divert any of its allowable 7 cfs from the stream. The grant, among other things, will fund repair of both intake structures.
