BACKGROUND

In 2002, Council for Watershed Health helped the Sanitation Districts of Los Angeles County and the Los Angeles Regional Water Quality Control Board collaborate with regional stakeholders to create the San Gabriel River Regional Monitoring Program. From 2004 to2014, the Council managed the highly acclaimed program.

Linked to this page are materials from the period of the Council’s management. Council for Watershed Health is proud of our accomplishments with this program. Our San Gabriel River 2010 State of the Watershed Report answered the five specific questions of interest to a broad range of stakeholders within the watershed:


What is the environmental health of streams in the overall watershed?

Are the conditions at areas of unique importance getting better or worse?
  (Source: 2010 Annual Report; last updated on 08/22/12)
   
Are receiving waters near discharges meeting water quality objectives?

Is body contact recreation safe?

Are fish safe to eat?

The San Gabriel River Regional Monitoring Program (SGRRMP) began development in 2004 by multiple stakeholders representing major permittees, regulatory and management agencies, and conservation groups. Development of the program was motivated by a permit condition for the Los Angeles County Sanitation District. The program seeks to increase awareness of issues at the watershed scale and improve the coordination and integration of monitoring efforts for both compliance and ambient conditions.


The SGRRMP is a watershed-scale counterpart to existing larger-scale regional monitoring efforts in the southern California region that seek to address questions and concerns about regional conditions and trends (State Water Resources Control Board Surface Water Ambient Monitoring Program, U.S. EPA’s Western Environmental Monitoring and Assessment Program, and the Stormwater Monitoring Coalition). Incorporation of local and site-specific issues within a broader watershed-scale perspective was and remains one of the unique features of the SGRRMP. By considering ways to improve overall cost effectiveness of monitoring efforts in the watershed, the plan includes reductions of redundancies within and between existing monitoring programs. Efforts within the program include targeted monitoring of contaminants of concern and adjustment of monitoring locations and sampling frequencies to better respond to management priorities.


Initiated in 2005, the multi-level monitoring framework combines probabilistic and targeted sampling for water quality, toxicity, and bio-assessment. By 2007 indicators to answer all five questions had been collected and evaluated. Initial results illustrate clear patterns between the upper (undeveloped) portions and lower (developed) portions of the watershed in terms of water quality and habitat condition. Finally, the results will help identify areas where expanded monitoring or special studies should be focused.
