Editing Vale of York (section)

===Drainage===
The Vale of York is drained southwards by the [[River Ouse, Yorkshire|River Ouse]] and its tributaries, the [[River Ure|Ure]], the [[River Nidd|Nidd]] and the [[River Foss|Foss]]. To the east of the area the [[River Derwent, Yorkshire|River Derwent]] drains southwards into the Ouse. There are also frequent stream courses and drainage channels which link with the main rivers crossing the vale. Many of these watercourses are maintained and managed by local [[internal drainage board]]s to ensure sustainable water levels are kept across the vale.<ref>[http://www.yorkconsort.gov.uk/index.php York Consortium of Drainage Boards]</ref>
