• The floods in 2021 in Germany laid bare the need to better integrate volunteers into official disaster management. An online survey with 1767 valid interviews after the floods in July 2021 reveals the shared experiences of professional and non-professional groups. Communication and coordination problems are the main results of the survey analysis. Overall satisfaction was a bit lower for the volunteers than for the professionals. The behavior of the superiors could have been more satisfactory. The preparation and opportunity for reflection could have been better after the operation. The information provision before and during the flood operation could have been more satisfactory. Worries were higher about elderly persons, and misinformation was a perceived danger. Problems experienced in the flood operations ranged from psychological stress to hygiene, self-endangerment, assignment of tasks, and misinformation, both from the media and official sources. Infrastructure-related problems included electricity, water, communication lines, roads, and rail. The suggestions for improvements ranged from communication and information about warnings and behavior to persons that transfer knowledge between organizations, digital exchange platforms, and exchange between countries.
