Flood Control
Between 1955 and 1961, an extensive flood control system was constructed along the Big Sioux and some of its tributaries in Sioux Falls to protect the city from a 100-year flood event. Features of the system include 29 miles (47 km) of levees, a floodwall in downtown, and a 15,000 feet (4,600 m) diversion channel with a dam at one end and a 118-foot (36 m) spillway at the other. The diversion channel connects two ends of the Big Sioux's natural loop around central Sioux Falls in an effort to channel floodwater away from the city. The levees then act to contain any floodwater either remaining in the natural channel or originating from Skunk Creek (whose mouth is downriver of the diversion dam). Additionally, a greenway covers much of the river's floodplain in southern and eastern Sioux Falls, further mitigating any property damage from high water.

Famous quotes containing the words flood and/or control:
“Hearing the low sound
of a cloud scattering rain
at midnight
and thinking for an eternity
on his absent young wife,
a traveller heaved a sigh
and with a flood of tears
howled the whole night long.
Now, villagers won’t let him stay
in their place anymore.”
—Amaru (c. seventh century A.D.)
“America is not so much a nightmare as a non-dream. The American non-dream is precisely a move to wipe the dream out of existence. The dream is a spontaneous happening and therefore dangerous to a control system set up by the non-dreamers.”
—William Burroughs (b. 1914)
