Investigations are taking place into how flood warning and defence systems can be improved in Lincolnshire after serious flooding this summer.
An Environment Agency spokesman has admitted the flood warning system for Louth did not sound early enough.
He said the series of warnings that lead to the alarm being sounded have been adjusted.
More studies are being done in Louth and Horncastle where heavy rain overwhelmed existing defences in June.
Ian Russell, from the agency, said they wanted to prevent such disasters in the future.
"We have inspected river banks to identify damage and are reinforcing embankments and talking to local people to find out exactly what happened and what needs to be done."
Studies are to be done to see what improvements need to be made in Louth, Horncastle and Grimsby, he added.
Next year more studies will be done in Wainfleet, Lower Witham, the Rasens and other areas.
Mr Russell said the county's warning system aims to alert residents two hours ahead of serious flooding, but flash floods poured off the Wolds into Louth very quickly.
"There is a very short response time between the rain and the run-off - we put off a flood watch on the Sunday before the flooding.
"But we didn't get the flood warning off as quickly as we would have liked."
The siren network in Lincolnshire was tested in August.
