The River Freshney is a river in the English county of North East Lincolnshire. The town of Grimsby stands on its banks. It rises from at least four springs on the edge of the Lincolnshire Wolds, although local folklore and oral tradition has it springing from Welbeck Hill. Originally it entered the tidal River Humber at Pyewipe, north west of Grimsby, but has been re-routed and now supplies Grimsby Docks. There was an existing haven within the borough of Grimsby but this suffered greatly with silting problems so in 1669 landowners agreed to the diversion of the Freshney through the town to the haven to provide fresh water and improve the flow. It is believed the work was completed in the very early 18th century.

Route

The river rises from a series of springs. The furthest south rises just to the north of Beelsby, close to the 200-foot (60 m) contour. It flows north and is joined by another stream which flows past some earthworks, dating from the English Civil War, before both pass under the A18 Laceby to Barnoldby le Beck road. Team Gate Drain rises just to the west of Waltham and flows to the west. It is joined by the stream from Welbeck Hill, which rises close to the A18 road and the 65-foot (20 m) contour. Having combined, they flow northwards, passing under the A46 road and the old course of the road through Laceby, both of which are called Grimsby Road. The river is called Laceby Beck as it flows along the eastern edge of Laceby.

Another stream from Aylesby joins before it passes between some lakes at Laceby Acres. The New Cut Drain runs parallel to the river from here, and they pass under the A1136 road and either side of the Freshney Bog Nature Reserve. Cromwell Road and the railway line to Grimsby cross in quick succession, after which the New Cut Drain follows the original course of the river, while the river turns sharply under the railway line to the docks, and under a series of bridges in Grimsby. These carry Boulevard Avenue, Earl Street and Alexandra Road over the channel. Another sharp turn brings the river into Alexandra Dock. There is a sluice with flap doors on it across the river at this point, and Freshney pumping station assists the discharge when water level prevent gravity discharge. Corporation Bridge is a grade II listed Scherzer rolling lift bridge and carries Corporation Road over the dock. It was designed by Alfred C Gardner, the Docks Engineer for the London and North Eastern Railway, and was installed in 1925 by Sir William Arrol & Co., an engineering company based in Glasgow. It has four cast iron and steel spans, one of which opens, and the structure, which replaced the previous swing bridge, was formally opened by the Prince of Wales on 19 July 1928. After the A180 Westgate road crosses Alexandra Dock, Union Dock connects it to Royal Dock, at the end of which a lock connects it to the Humber.

Hydrology

Freshney Bog was constructed in 2001 as a washland, which could be used to hold excess water when the channel below it could not cope with the flow in the river. It is a major part of the flood defence system for Grimsby. During the floods of 2007, more than a full month's rainfall fell in 24 hours on the river catchment. Groundwater levels rose by over 16 feet (4.9 m) in the week prior to the floods, and with the ground saturated, the capacity of the river and the New Cut Drain was exceeded. Freshney Bog storage area filled up, but had insufficient capacity for the volume of water, and as a result, flooding occurred, which affected 200 houses. At Laceby Beck gauging station, normal levels of the river vary between 0.62 and 2.55 feet (0.19 and 0.78 m), but on 2 April 2018, they reached 3.46 feet (1.05 m) at 21:15 BST. This height is believed to be the highest the river has reached since measurements began.

It was previously thought that a level of 2.43m was reached in 1985. At that height, Grimsby Town centre and the West Marsh areas would have been under 1-1.3m of water. The Environmental Agency have since updated this anomaly as no flood occurred to that extent in 1985.

The Environment Agency carried out flood alleviation work on the New Cut Drain in 2013, to reduce the risk of properties flooding. This work was planned after the significant flooding event that occurred on 21 July 2007 when the river rose to a record (at the time) 3.25 feet (0.99 m). The work involved sheet piling of some 770 yards (700 m) of the drain, and installation of perforated filter drains to collect surface water. A new flood bank between the river and the Willows Estate was constructed, and parts of the existing bank between the New Cut Drain and the Freshney Washland Flood Storage Reservoir were removed, to allow more water to be impounded when river flows are high.

Water Quality

The Environment Agency measure water quality of the river systems in England. Each is given an overall ecological status, which may be one of five levels: high, good, moderate, poor and bad. There are several components that are used to determine this, including biological status, which looks at the quantity and varieties of invertebrates, angiosperms and fish, and chemical status, which compares the concentrations of various chemicals against known safe concentrations. Chemical status is rated as good or fail.

The water quality of the Freshney was as follows in 2016. The ecological and overall status have improved since 2014, when both were rated bad, and the chemical status was rated fail. The reasons for water quality being less than good include physical modificiation of the channel, groundwater abstraction, sewage discharge and poor soil management of the surrounding agricultural land.

Section	Ecological Status	Chemical Status	Overall Status	Length	Catchment
Laceby Beck / River Freshney Catchment	Poor	Good	Poor	9.7 miles (15.6 km)	39.06 square miles (101.2 km2)

The Friends of the Freshney was formed in the 2000s under the Chairmanship of Chris Scott, and have organised regular clean-ups of the lower river, primarily the stretch that goes through the Duke of York Gardens in Grimsby.Currently the group meet at the Fire Station in Cromwell Road, with former West Marsh councillor Keith Watkin as Chair
