The municipality of Jablanica, about 70 km (43 miles) southwest of the capital Sarajevo, where the deaths were reported, was completely cut off after road and railway links were destroyed.
Bosnia's inter-ethnic presidency - a Bosniak, Serb and Croat tripartite - said it requested military help for the wider Jablanica area, and engineers, rescue units and a helicopter were deployed, including to rescue 17 people from a mental hospital.
Some houses had been reduced to rubble by landslides, in what appeared to be Bosnia's worst flooding since at least 2014, when more than 20 died in floods.
