Residents are being urged to take precautions after the Environment Agency issued flood alerts in Lincolnshire.
The amount of rain in recent days has resulted in three new alerts along various watercourses in Lincoln, the lower River Witham from Lincoln to Boston and various minor rivers in North Kesteven.
The levels of water in Lincoln have risen sharply and will remain high for several days, with the affected areas being the River Witham, Sincil Dyke, Great Gowts Drain, Fossdyke Canal, Boultham Drain and the Brayford Pool.
A spokesman for the Environment Agency said: "We are monitoring the situation closely and are preparing to operate the flood storage reservoirs which protect properties in Lincoln from flooding."
Other tributaries along the lower River Witham from Lincoln to Boston, such as in Woodhall Spa, Coningsby, South Kyme and Bardney may also be affected.
The weekend rain has also caused river levels in North Kesteven to rise, with flooding of low-lying land and some roads.
The affected areas are Heighington, Dunston, Blankney Becks, Billinghay Skirth and the River Slea. Various tributaries with high water levels may also affect parts of Scopwick, Digby, Ruskington, South Kyme, Sleaford, Ancaster, Wilsford and Kelby.
The only current flood warning in Lincolnshire was issued early this morning in Swaton, near Sleaford, after around 25mm of rain fell overnight. Low-lying properties near the river are most at risk.
Further rainfall is forecast for Monday and Tuesday, so river levels are likely to remain high across the county for several days.
