On the Delaware River, life vest requirements are strictly enforced by the National Park Service (NPS) and state agencies to ensure water safety. For the Delaware Water Gap National Recreation Area, the law mandates that all children aged 12 and under must wear a Coast Guard-approved life jacket at all times while on the river. For adults, while you are not always required to wear the vest (depending on the water conditions and time of year), you must have a wearable, properly sized USCG-approved life jacket on board and readily accessible for every person in your vessel. However, from November 1 through April 30, all boaters on vessels less than 16 feet (including canoes and kayaks) must wear a life jacket at all times due to the risk of cold-water shock. Rangers frequently patrol the river and can issue significant fines for non-compliance. Given the river's hidden currents and slippery limestone bottom, "Wear It!" is the primary safety recommendation for all visitors, regardless of their swimming ability or age.
