Shattemuc is a private club with membershipsfor boats, kayaks, pool and social. Membership required, no spray park here. Go to shattemucyc.org for more info.
No spray park at Shattemuc, but I believe there is one at the southern end of Westerly road, at the foot of Louis Engel Waterfront Park, and just north of the water treatment plant and lower portion of the prison. https://www.villageofossining.org/recreation-and-parks-department/pages/spray-park
There is a pool at the Shattemuc Yacht Club, which is a members only club, but I don't recall seeing a spray park there. Is it by the pool area?
