The Los Angeles River Regional Monitoring Program (LARRMP) began in 2009 with the goal of tracking the answers to five questions: (1) What is the condition of streams associated with the Los Angeles River? (2) Are conditions at areas of unique interest getting better or worse? (3) Are receiving waters near discharges meeting water quality objectives? (4) Is it safe to swim? (5) Are locally caught fish safe to eat? A series of annual reports have been issued answering these questions. This report, the most recent as of 2017, summarizes the methodology and presents the results for the given years. Areas of focus include biotic and riparian zone condition, water chemistry, toxicity, physical habitat condition, high value habitat sites, and bacteria levels.
