Upcoming Water Monitoring Classes


Would you like to volunteer monitoring the water quality of local creeks? Sno-King Water Watchers is a Community-Based Water Monitoring program in the King and Snohomish Counties.  To become a monitor, sign up for our Zoom-based classes, and then schedule practical training. You can find information on our current classes listed below.  To schedule, send an email to snokingwatershedcouncil@gmail.com.

Introduction to Water Monitoring – May 26, 7-8:30 pm via Zoom

Learn about streams and watersheds, types of pollutants, how citizens can gather credible data about their local waterbodies, action strategies they can employ to improve water quality while engaged in Community-Based Water Monitoring. This class is a prerequisite for the other classes listed below.

Bacteriological Monitoring – June 9, 7-8:30 pm via Zoom

What are bacteria? Which ones are harmful? What are standards for E.Coli in Washington waters? Learn about simple, low-cost methods available to citizen scientists to evaluate their local waterbodies for bacteriological contamination.

Physical/Chemical Monitoring – June 2, 7-8:30 pm via Zoom

Water temperature, dissolved oxygen, and pH are all important variables for local salmonids and other creatures that live in our streams. Clear, clean water is important too. Learn to use a citizen science kit to monitor these important variables.  

Stream Biomonitoring – June 1, 7-8:30 pm via Zoom

Insects and other “benthic macroinvertebrates” (water-living small creatures without skeletons) that live in streams can tell us a lot about the health of a water body. Learn how to collect, identify, and classify these creatures and use them to evaluate stream health.

Practical skills training

After completion of one or more of the above classes, to complete your training you will attend a practical session. Practical skills vary for each class and include performing all the water chemistry tests using a LaMotte kit, measuring turbidity with a turbidity tube, sampling for bacteria, and plating bacteria samples in Petri dishes.  For Stream Biomonitoring, a separate session is conducted to collect macroinvertebrate samples, identify and classify them, and obtain an index of water quality.

Practical training is the final step to get certified as a Global Water Watch water monitor with our program.
