Saturday, October 22
NOVA Stream Monitoring Certification Training
Time: 9am - 3pm
Location: Manassas Battlefield National Park

Open to all volunteers, including those not yet ready to seek certification. This two part workshop will include a morning indoor presentation (9am - noon) that will introduce urban watersheds, the science of stream monitoring, and identification of common stream invertebrates. The afternoon session (12:30 - 3pm) will be outdoors at Young's Branch Stream where we will take a full stream sample and identify and count all the invertebrates we find. Those not seeking certification can attend either session or both. Those seeking to become certified must attend both sessions, take the written test at the end of the morning session, and adequately demonstrate field skills during the afternoon session. Once certified, a volunteer can adopt their own stream site and monitor it quarterly with equipment supplied by their Soil and Water Conservation District. Jointly organized by the Northern Virginia and Prince William Soil and Water Conservation Districts. To register, please contact Dan Schwartz.

All dates are subject to cancellation and changes. For more up-to-date information, please contact Dan Schwartz.

How Stream Monitoring Works

group uses net to catch insects in streamWe train volunteers to assess ecological conditions in streams based on the presence and abundance of benthic macroinvertebrates (aquatic insects). Volunteers also learn how to take chemical measurements about nitrate/nitrite and turbidity. Training includes indoor and field workshops and mentoring by experienced monitors.

The Northern Virginia Soil and Water Conservation District provides all the training and equipment you need. No prior experience is necessary. Volunteers can monitor at different levels of commitment. You may choose to assist other monitors when it is convenient for your schedule. Or you may adopt your chosen stream and commit to monitoring it four times a year. We will make the program work for you!

NVSWCD reviews and certifies the data and forwards it to the Fairfax County Stream Protection Strategy Program, Virginia Department of Environmental Quality, and Virginia Save Our Streams.
