Herring Run is an urban stream surrounded by mostly park located in Northeast Baltimore City. It feeds the Back River which is the tidal estuary that connects it to the Chesapeake Bay. Herring Run flows through the piedmont geologic formation and into the coastal plain. It is named for the herring, a fish that lives in salt water and spawns in fresh water streams, that used to spawn in its stream. Over 31 square miles of land drain from the watershed into the stream supply its running water.

The stream is surrounded by forests that provide opportunity for hiking, bird watching, nature play, and running. Our parks are used by dog walkers and sports enthusiasts. Cross country, football, soccer, soft and base ball users all use various fields in the park. There is a half court basketbal court near Harford Rd. The main portion of the park where people access it lies between Harford Rd. and Belair Rd. along Chesterfield Ave. There is also a bike path that runs along the stream to Sinclair Ln. Deer, fox, birds, squirrels, turtles and other animals inhabit our park. There are forests, wetlands, stream edges, open meadows and lots of mowed grasslands for use by all creatures.

This stream is home to over 10 species of fish but is polluted by leaking sewers and the polluted runoff when it rains in the watershed. Unfortunately, trash is a common visual pollution that takes away from the beautiful stream edge. Neighborhoods, the Friends of Herring Run Park, and the Herring Run Watershed Association are working to improve the park's environment and recreational opportunities. Baltimore City and County are working to remove sewage from our streams and make our neighborhoods cleaner and greener. Get involved and volunteer today to make a difference.
