The River Riccal is a river of North Yorkshire, England, lying within the North York Moors National Park. It is a tributary of the River Rye, which in turn is a tributary of the River Derwent. The name originates in the fourteenth century as Ricolvegraines means Rye Calf, where Calf is a small island near a larger one. This describes the way the river, and those nearby, form islands as their nature changes due to meandering.[1]

Some writers have misspelled the river Riccall,[2] possibly in confusion with an unconnected village in North Yorkshire. The Riccal name was also the name of a Rural District before 1935. The river is under the management of the Rye Internal Drainage Board, a member of the Vale of Pickering IDBs.[3]

Course

Cowhouse Beck and Bonfield Gill meet at the end of Lund Ridge at Coning's Birks in Hag Wood to form the Riccal. The river meanders south and south-east through woodland, passing the villages of Carlton and Pockley. It emerges into open countryside to the east of Helmsley and passes under the A170 and continues south towards Harome. Here it turns east south-east to join the River Rye at High Waterholmes in Ryedale just a half mile from the confluence of the River Rye and River Dove.

The typical river level range at the Nunnington Environment Agency measuring station is between 0.16 metres (0.52 ft) and 0.44 metres (1.4 ft).[4] The Tabular Hills Walk crosses the river above Carlton.[5]

Geography

The river valley, or Dale, is part of the range of upland called the Tabular Hills on the southern boundary of the North York Moors. This describes the flat or table top appearance of the summits of these ridge tops. The primary geology is limestone and calcareous sandstone with dale itself being the result of glacial run-offs.[6]

History

About a mile from the village of Beadlam are the remains of a Roman villa situated on the east bank of the river. They were uncovered and investigated in 1969 and date from the fourth century.[7]
