Monthly Data

On the second Friday of every month, the Storm Drain Detectives monitor the Mokelumne River using five different water quality tests at nine sites along the River and Lake.  The measurements are recorded and posted by month on this page.  Along, with these measurements, comments are also included.  Each measured value is assigned a grade of A, B, C, D, or F.  Each test has its own grading scale.  These grades help to indicate the condition of the river or storm drains at the individual site locations.  Try comparing a site's grade from one month to the next, or compare one site to another to see if that part of the river is declining or improving.  Definitions for terms that are used on the monthly charts can easily be defined  in the Glossary link.  Explanations of the five water quality tests can also be found in the What are we looking for? link.  The river sites are listed by numbers on the monthly charts that correspond to their location and description in the Mokelumne River Map link.  

Have fun watching developments in the river's checkup from month to month.  Is the site nearest your house receiving good or bad grades?  Using our measurements and the other resources available on the Storm Drain Detective's web site, hopefully you can learn more about the impact you make on storm drains and the river.
