Upcoming Water Monitoring Classes

Would you like to volunteer to monitor the water quality of local creeks? Sno-King Water Watchers is a Community-Based Water Monitoring program in the King and Snohomish Counties.  You can take our classes and become a volunteer water monitor.

Classes in series:

Introduction to Water Monitoring

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. Zoom class.

Bacteriological Monitoring

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. Zoom class.

Physical/Chemical Monitoring

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.  Zoom class.

Physical/Chemical Monitoring field 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.  Field class, 2.5 hours.

Stream Biomonitoring

Did you know that there is a whole community of insects that live on the bottom of your local streams? Stream bugs are a great indicator of stream health. Learn how to collect, identify, and categorize these creatures. Zoom class.

Stream Biomonitoring field training

Field assessment of benthic macroinvertebrates. Learn how to collect, identify, and categorize these creatures. Create an index of water quality based on pollution tolerance of creatures found. Field session, 2.5 hours.

BIBI (Benthic Index of Biotic Integrity)

Learn about this quantitative method of collecting and analyzing benthic macroinvertebrates. After training, you can participate in field collection activities. Zoom class, combined with Stream Biomonitoring Class.

Streamflow monitoring

Stream flow is an important variable in stream monitoring. Stream flow varies with stream order, size of watershed, rainfall, stormwater, and other factors. In this class, learn how to measure and calculate stream flow using simple citizen science techniques. Zoom class.

Habitat assessment

Trees and shrubs, shading, large woody debris, gravel, rocks, sand, and other factors in a stream and in its riparian zone (the area of vegetation around a stream that affects the stream) have a large effect on the health of the stream and how good of habitat it is for fish and other stream inhabitants. Learn how to use a stream habitat assessment tool to evaluate and document habitat in and around a stream. Zoom class in conjunction with Streamflow monitoring.

Streamflow & habitat practical

Put your knowledge to use in the field with hands-on practice at a stream site. Field session, 2.5 hours.
