Hidden Creek Critters

There are tiny critters on the bottom of the creek! Larvae for various flies and beetles are critical for the biodiversity and survival of our watershed.

Creek Critters include larvae for dragonflies, damselflies, mayflies, and stoneflies, as well as aquatic worms, leeches and beetles that provide food for our fish, frogs and birds. They are sensitive to pollution and therefore good indicators of water quality. Unfortunately, we tend to find only the hardy critters and so the creek is rated Fair.

FoCJC has a water quality monitoring team that checks 4 times/year for their existence and for chemicals in the creek. We partner with Audubon Naturalist Society and Izaak Walton League of America to report these findings up the chain to support the health of the Chesapeake Bay. To lend a hand with our monitoring program contact us at

In the winter, we partner with the Izaak Walton League of America on their SaltWatch program, so help us out as citizen scientists, go to SaltWatch and get your free kits! This data is critical to maintaining creek health. You can help by reducing the amount of salt you use in your driveways/sidewalks to melt ice.

Did you know there is a new pesticides law for private lawn care? We all need to do our part to protect our streams and rivers.
