just before stamford, the great north road, now labelled the a1, crosses the river, and a pumping station on the north bank at stamford meadows has pumped large quantities of water to the rutland water reservoir since its construction in 1975. stamford was the lowest point at which the river could be forded so the roman ermine street crossed the welland there. the a16 road crosses the river by a three-arched stone bridge designed by edward browning in 1845. below it, albert bridge is made of iron with stone piers, and was erected by stamford town council in july 1881, to replace an earlier bridge which was washed away in a flood. beyond stamford, the river passes the site and ruins of the benedictine st leonard's priory. hudd's mill marks the point at which the stamford canal left the river. the present mill building dates from 1751 and 1771. the river gwash, which the canal crossed on the level, joins from the north, and the remains of the canal follow the river on its north bank. below uffington, the county border follows the old course of the river, first to the south to tallington and then to the north, while the main course now flows along the maxey cut to peakirk. the old course consists of two streams, fed by sluices from the maxey cut, which meander to the deepings. the eastern stream supplied power to lolham and maxey mills, while the western stream did the same for tallington mill, which dates from around 1700, west deeping mill, and molecey's mill, which still retains its seventeenth-century undershot waterwheel, modified in the 19th century to poncelet's improved design, and the only surviving waterwheel of its type in lincolnshire. at the western edge of market deeping the two streams join, and they are also joined by the greatford cut, which has carried the diverted waters of the west glen river since the early 1950s.
