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:
“There are flood and drouth
Over the eyes and in the mouth,
Dead water and dead sand
Contending for the upper hand.
The parched eviscerate soil
Gapes at the vanity of toil,
Laughs without mirth.
This is the death of the earth.”
—T.S. (Thomas Stearns)
“If the technology cannot shoulder the entire burden of strategic change, it nevertheless can set into motion a series of dynamics that present an important challenge to imperative control and the industrial division of labor. The more blurred the distinction between what workers know and what managers know, the more fragile and pointless any traditional relationships of domination and subordination between them will become.”
—Shoshana Zuboff (b. 1951)
