The depths of the water at high and low tides vary seasonally, with the phase of the moon, and with position of the moon relative to the sun. Back and forth movement of water with tides is 12 miles, so that, for example a seed produced downstream along the Delaware River could find its way upstream into the Marsh.There were no tides in the region 1200-1500 years ago.Salty water occurs south of Philadelphia. ![]() Tidal water at the Marsh is fresh water.There is considerable time lag: high tide at Hope Creek was at 10:35 AM while at Trenton it was 2:40 PM. For example on Oct 17, 2009, high tide was 6.6 feet at Hope Creek, about 0.6 mile above the beginning of the Delaware River (elevation above sea level = 3 feet), while at Trenton, 125 miles up river (elevation = 52 feet), high tide was 9.5 feet. Interestingly, this effect is amplified up river. Thus, as the tide rises in the Delaware, the water shifts upstream and the water level in adjoining creeks and wetlands, such as Crosswicks Creek and the Marsh, also rises. As the ocean tide rises, a large amount of water enters the bay, and as it moves the volume is constricted, and tidal water is forced up river all the way to the Falls at Trenton. The ebb and flow of water along the New Jersey coast is felt in Delaware Bay and all the way up the Delaware River to Trenton. Tides are the result of force created by the earth as it rotates on its axis and the gravitational pulls of the moon and the sun. Along the east coast of North America, they are semidiurnal, with two high and two low tides each day. Tides are daily rhythms, as dependable as day and night.

The tides in Bordentown are about the same as those in Trenton.
