Geography
Gray's Bay Dam on the Lake's eastern end helps control Lake Minnetonka's water level. This structure is also called the Headwaters Control Structure of Gray's Bay. The flow over the Dam ranges from zero to 300 cu ft (8.5 m3) per second or a daily rate of up to 26 million US gallons (98,000 m3). Evaporation from Lake Minnetonka can be as high as 50 million US gallons (190,000 m3) a day. According the Minnehaha Creek Watershed District, annual evaporation from the Lake is about 30 inches (760 mm) of water, or 11.5 billion US gallons (44,000,000 m3). This is countered by an average rate of 28 inches (710 mm) of rainfall, and 20 inches (508 mm) of run off.

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)
“Where the heart is, there the muses, there the gods sojourn, and not in any geography of fame. Massachusetts, Connecticut River, and Boston Bay, you think paltry places, and the ear loves names of foreign and classic topography. But here we are; and, if we tarry a little, we may come to learn that here is best. See to it, only, that thyself is here;—and art and nature, hope and fate, friends, angels, and the Supreme Being, shall not absent from the chamber where thou sittest.”
—Ralph Waldo Emerson (1803–1882)
“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)
