Flood warnings are still in place on several rivers in Lincolnshire, but environment officials say river levels are stable after a day of heavy rain.
Louth was badly flooded last summer
East and West Lindsey districts were worst affected, but south Lincolnshire escaped relatively unscathed, the Environment Agency said.
Flood warnings are still in place in Horncastle, Louth and Langworth.
There is also a severe flood warning for the River Ancholme around Brigg and Scotter, but levels are falling.
The warning on the River Ancholme coincided with a high tide on the Humber Estuary at 1800 GMT on Monday.
Earlier on Monday, residents in Louth were warned about possible flooding as water levels rose on the River Lud.
The Environment Agency sounded flood sirens in Louth and Horncastle early to give people advance warning.
There were also some reports of flooded properties around Middle Rasen. Louth was flooded twice in 2007 during heavy rain in the summer.
An Environment Agency spokesman said: "Just because the sirens stop does not mean the threat of flooding is over. We don't want people to panic but we do want to warn them."
Drivers were warned of standing water on roads in the Louth area.
Bette, a Louth resident who was flooded twice last year and is facing a further flood threat, said she could not believe the bad weather had returned.
"It is extremely worrying but I imagine there were more than 100 people in the town who didn't get any sleep last night," she said.
A flood warning was also issued for Stainfield Beck and a flood watch was in place for the Fossdyke Canal from Torksey Lock to Lincoln.
