Stream Monitoring - Critter Counting Family Fun!
Winter, Spring, Summer, & Fall


GET YOUR BRAIN WET! Join Friends of Lake Accotink Park and Friends of Accotink Creek for a rewarding and fun time for adults and children who enjoy helping our parks and environment by identifying and counting stream critters to document the health of the stream.

It's fun for the whole family to learn what's in the water by seeing and counting stream critters. The critter count is ever-changing, but we have made some exciting finds, including small crayfish.

Our monitoring workdays are on the second Saturday of the months of March, June, September and December. Please see our Calendar to verify times and click on "RSVP" so we know you are coming.   Directions

Please dress for the weather. We suggest you bring boots suitable for wading. All other equipment and educational instruction are provided. E-mail us with questions or comments!

We appreciate you and your help!

Learn more of the why and how of stream monitoring with this quick online training course.

The data volunteers collect gets reported to Virginia Save Our Streams (VASOS) which keeps an online database of many stream monitoring sites state-wide and reports data to the Virginia Department of Environmental Quality (DEQ). If the volunteer data is showing bad results at certain streams, DEQ will target those streams for their own monitoring program in the next fiscal year, and the data they collect can then be used to guide any required restoration work, especially through the creation of Total Maximum Daily Loads (TMDL).
