The document incorporates a methodology for recording floods in the Greater La Plata region based on a survey in a local newspaper (El Día) covering the period from 1911 to 2014. The main results refer to an analysis of floods according to the type of precipitation event, the affected localities, and a recognition of the critical years. This methodology can lead to new lines of research and collaborative plat forms, such as applications for ear ly warning, prevention and mitigation, and to strategies oriented to recognize the social perception of risk.
