Geography
Located within the Gulf of Maine watershed, the Great Bay Estuary is a drowned river valley composed of high-energy tidal waters, deep channels and fringing mudflats. The entire estuary extends inland from the mouth of the Piscataqua River between Kittery, Maine, and New Castle, New Hampshire through Little Bay into Great Bay proper at Furber Strait, a distance of 12 miles (19 km). The Great Bay Estuary is a tidally-dominated system and is the drainage confluence of three major rivers, the Lamprey, Squamscott, and Winnicut. Four additional rivers flow into the system between Furber Strait and the open coast: the Cocheco, Salmon Falls, Bellamy, and Oyster rivers.
The Piscataqua River is an ocean-dominated system extending from the Gulf of Maine at Portsmouth Harbor and forming the border of New Hampshire and Maine to the fork of its tributaries, the Salmon Falls and Cocheco rivers. These rivers, several small creeks and their tributaries and ocean water from the Gulf of Maine create the Great Bay estuarine hydrosystem. The tidal range is dramatic within Great Bay. Average depth of the embayment is 2.7 metres (8.9 ft) with channels extending to 17.7 metres (58 ft). The water surface of Great Bay covers 8.9 square miles (23 km2) at high tide and 4.2 square miles (11 km2) at low tide, leaving greater than 50% of the bay exposed at low tide.

Famous quotes containing the word geography:
“The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.”
—Willard Van Orman Quine (b. 1908)
“The California fever is not likely to take us off.... There is neither romance nor glory in digging for gold after the manner of the pictures in the geography of diamond washing in Brazil.”
—Rutherford Birchard Hayes (1822–1893)
“Ktaadn, near which we were to pass the next day, is said to mean “Highest Land.” So much geography is there in their names.”
—Henry David Thoreau (1817–1862)
