To keep the streets of Lodi from flooding during rainstorms, a storm water system has been engineered to send rainfall into the Mokelumne River or into the Woodbridge Irrigation Dam canal system. In a perfect world this wouldn’t be a problem. But, in the real world, storm water has the potential to also carry street pollution to a local waterway, uncleaned.
Established in 2000, the Storm Drain Detectives are a group of teachers, students, and community members, in partnership with the City of Lodi, Public Works Department, that monitor the Mokelumne River monthly at several different sites where stormwater enters the river. Using water quality tests, visual assessments, and toxicity tests, the Storm Drain Detectives collect and record data to analyze the effects that storm drain run off has on the river.
These programs have been developed in cooperation with the State Water Resource Control Board, Clean Water Team.
To ensure data is properly collected, a quality assurance project plan (QAPP), which was approved by the State Water Resource Control Board in 2002, is followed by the participants in the program, and is available for review upon request.
