Join The River Project on deck and learn about what lives beneath the surface of the Hudson River during the Great Fish Count, an annual activity organized by the World Science Festival. LILAC is one of 18 participating sites and opens early on Saturday for this special program. Help count the many species of fish and marine creatures (even seahorses) right here in our own city waterways when TRP biologists pull up the traps hanging below LILAC. This event is free and open to the public.
