After Milner Dam was constructed, agricultural production in south-central Idaho increased substantially. In 1909, the privately owned Twin Falls Land and Water Company was reorganized as the shareholder-owned Twin Falls Canal Company. Twin Falls became a major regional economic center serving the agriculture industry, a role which it has sustained to the present day. The city became a processing center for several agricultural commodities, notably beans and sugar beets. In later years, other food-processing operations augmented the local economy. By 1960, Twin Falls had become one of Idaho's largest cities, though its origins were still within living memory for many. Twin Falls became the center of national attention in September 1974, when daredevil Evel Knievel attempted to jump the Snake River Canyon in a specially modified rocket cycle. Watched by millions on closed-circuit television on a Sunday afternoon, the attempt ultimately failed due to high winds and a premature deployment of Knievel's parachute. The launch ramp's foundation lies on private land on the canyon's south rim. Less than 2 miles west (3 km) of Shoshone Falls, it is still visible (). During the last quarter of the 20th century, gradual diversification of the agriculture-based economy allowed the city to continue to grow. Major Twin Falls employers in 2006 included computer maker Dell, Inc., Glanbia, and Jayco, a recreational vehicle manufacturer. In September 2009, Dell announced it would close its Twin Falls facility by January 2010. Later in 2010, the call center company C3 opened a facility in the former Dell location. In recent years, Twin Falls has become quite multicultural. Due in large part to a refugee center operated by the College of Southern Idaho since 1995, significant numbers of people from Bosnia and Herzegovina and the former Soviet Union have settled in Twin Falls. The city also has a sizable Hispanic population. Government Twin Falls is one of only three Idaho cities that has a council-manager form of government. The seven-member Twin Falls city council is directly elected in nonpartisan municipal elections to four-year terms. The mayor, who holds little executive power, is periodically selected among current city council members to chair meetings, and is "considered the official representative of the city." City council meetings are usually held on Mondays. The city's day-to-day operations are overseen by
