Marshes are divided into distinct zones, the high marsh and the low marsh. The difference in elevation between these two areas is usually only a few centimeters, but for the plants that inhabit each of these zones, a few centimeters makes a world of difference. The low marsh floods daily at high tide.alt marshes are a mosaic of snaking channels called tidal creeks that fill with seawater during high tides and drain during low tides. Fish species including flounder and mullet live most of their lives in marsh creeks. (top) Levees are areas of higher ground that border the marsh creeks.

But as you go further out (follow chart down) 8, 10 , 12, 14 feet, the capacity is greatly reduced.
