The Hidden Rivers Walk is a collaboration by North Brooklyn Parks Alliance and Billion Oyster Project.

Using a historic watershed map created by urban ecologist Eymund Diegel, the walk begins at Transmitter Park where the watershed is visible, with a discussion about water quality, storm water, & sewage. We’ll make our way to Bushwick Inlet, where we’ll discuss ecological & industrial history and modern community activism. Participants continue to McCarren Park, following the pathways of “hidden rivers.” We’ll discuss how these tidal waterways were buried in the 19th and 20th century and rerouted into sewers to make room for the development of modern communities, which today are often sites of flooding.

This walk coincides with Riverkeeper Sweep, a day of action for our waterways. We may have additional special speakers!
