ing. The last important episode, in 1986, affected several neighbourhoods of the north-east of Rosario (notably the ''barrios'' of Ludueña Norte and Empalme Graneros, where water was almost 2 m deep in some points). This flood sparked a grassroots movement to pressure the provincial government to fund preventive measures. A length of 1.5 km of the Ludueña Stream were piped into five underground closed conduits, with a cross section of 74 m², which cross densely populated areas and resurface to empty the stream into a final open section a few hundred metres from the Paraná River. In 1995, after two-year works, an earth-fill

March 2007 floods

Between the end of March and the beginning of April 2007, more than a week of increased rainfall in a wide area around the Paraná- Plata basin raised the level of the Paraná River and many of its tributaries. The Ibarlucea Canal, which empties into the Ludueña Stream, overflowed and caused the evacuation of several thousand people. The Ludueña Stream did not actually overflow, but brought alarm to the populous neighbourhoods which had suffered from floods in the past. Some works that were needed to prevent the overflow of the Ibarlucea Canal had not been finished. It was later shown that if they had, the extra flow would have moved into the Ludueña proper and brought it over the brink.
