Members of the Southwell Flood Forum have received training in road closures in advance of any potential flooding this winter.
The town was badly affected last Summer after four inches of rain fell in just an hour, leaving more than 200 homes damaged.
Volunteers will now be able to put up warning signs and close roads if similar conditions occur again, once consent has been given from local authorities.
