A Watershed in Time: Exploring the Patapsco's Past, Present and Future
What is a watershed? Perhaps that question peaks your curiosity or you think you can answer what seems like a basic question but may not be so simple. Whatever your circumstance, check out our new Watershed in Time short video to learn more about watersheds and what you can do to help improve watershed health in the Patapsco and beyond. We developed two short videos with funding support from the Kahlert Foundation and are looking to expand on the topics presented to produce a more comprehensive story of watersheds using the Patapsco Valley as the focus.

Mayflies are one of the insects we frequently encounter during our monitoring of the Patapsco River. They spend most of their lives as an aquatic nymph and then emerge to live as a winged adult for about 24 hours. Mayflies can be distinguished from other aquatic nymphs by their three distinct tails (though some have only two) and a set of gills along the abdomen. Check out this video of a Mayfly using its gills to get dissolved oxygen from the water!
Mayflies are sensitive to pollution, so their absence may be a sign that the waterway is not healthy enough to support them. We are pleased to report that we have found mayflies at many of our Patapsco River monitoring sites this spring.
Stay tuned for a wrap-up post about our spring 2024 biological monitoring season!
Check out this video of a Common Watersnake spotted near the Patapsco River!
Common Watersnakes (Nerodia sipedon) are found throughout Maryland. They are often mistaken for two venomous snakes: the Eastern Cottonmouth and the Eastern Copperhead.
Eastern Cottonmouths (also known as Water Moccasins) do not live in Maryland.
Eastern Copperheads are not aquatic and have distinctive brown “Hershey Kiss shaped” markings on their bodies.
Common Watersnakes vary widely in body patterns and can have similar markings to Copperheads. In the Patapsco Valley, if you see a snake in the water, it is most likely a Common Watersnake. Although nonvenomous, they will bite if threatened. It is best practice to keep your distance and do not attempt to handle any snakes you encounter.

Do you want to learn more about a stream in your backyard or neighborhood? Have you wondered where it goes or if there are any water quality issues?
There are a few free resources that can answer your questions and help you learn more about your local waterways.
“How’s My Waterway” is a resource created by the Environmental Protection Agency (EPA) to help provide the public with information on the condition of local waterways. Begin by entering your zip code or location. “How’s Your Waterway” will display data that has been gathered about the waterways within your local watershed, including the condition and any identified issues.

The U.S. Geological Survey’s (USGS) “Science in Your Watershed” is a web resource that helps users find scientific information about watersheds in their region.

Mayflies are found throughout North America. They spend most of their lives as aquatic insects and need healthy waterways to survive. Because they are sensitive to pollution, they are considered a bioindicator species and can help determine the health of the water from which they are found.
In the Patapsco watershed, we've spent April and May visiting local streams sites and looking for sensitive organisms like these.
Check out this short video of two different types of mayflies that we collected. In addition to a head, three sets of legs, and three tails, one key characteristic of mayflies is the gills along the abdomen. Mayflies use the gills to fan water (and dissolved oxygen) into their bodies. Look for the gills moving on the smaller of the two!
