The major aquifers are the Corallian limestone, chalk and Sherwood sandstone. The Corallian Limestone outcrops on the hills surrounding the Vale of Pickering and is made up of a series of limestones and sandstones. This aquifer is unconfined in parts and gets water from the River Rye and River Derwent through <a href="/wiki/Swallow_hole" class="mw-redirect" title="Swallow hole">swallow holes</a>.<sup id="cite_ref-CAMS_2-0" class="reference"><a href="#cite_note-CAMS-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p><p>Before the <a href="/wiki/Last_Glacial_Period" title="Last Glacial Period">last ice age</a> the waters of the upper Derwent flowed east and discharged into the sea at Scalby, near Scarborough.

For this purpose there was an interest in improving navigation on the Derwent as far as Malton. In 1702 an <a href="/wiki/Act_of_Parliament" class="mw-redirect" title="Act of Parliament">Act of Parliament</a> was passed authorising its proprietors to improve the river. Towpaths were laid out and "locks, turnpikes, pens for water, wharfs and warehouses" were constructed. The promoters of these works were allowed to charge tolls on the cargo carried on any part of the river. </p> <figure class="mw-default-size mw-halign-right" typeof="mw:File/Thumb"><a href="/wiki/File:Ings_Bridge_Wheldrake.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/3/32/Ings_Bridge_Wheldrake.jpg/220px-Ings_Bridge_Wheldrake.jpg" decoding="async" width="220" height="150" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/3/32/Ings_Bridge_Wheldrake.jpg/330px-Ings_Bridge_Wheldrake.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/3/32/Ings_Bridge_Wheldrake.jpg/440px-Ings_Bridge_Wheldrake.jpg 2x" data-file-width="640" data-file-height="435" /></a><figcaption>The Old Ings Bridge over the River Derwent at <a href="/wiki/Wheldrake" title="Wheldrake">Wheldrake</a> in 1961</figcaption></figure> <p>The owners of land near to the river complained in 1722 that the new locks and weirs caused them to lose income because their meadows were more often flooded. In 1793 thirty five vessels were trading from Malton, carrying corn downstream to the West Riding towns and returning upstream with coal. Virtually every village and hamlet near the tidal river had its own landing place.<sup id="cite_ref-Jones_7-2" class="reference"><a href="#cite_note-Jones-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> </p><p>In 1845 the <a href="/wiki/York_and_North_Midland_Railway" title="York and North Midland Railway">York and North Midland Railway</a> was built to join the West Riding to Scarborough via Malton. Much of the freight traffic of the Derwent Navigation was transferred to the cheaper railway. In 1855 the railway managers bought the Navigation and to further stifle competition they charged high tolls on barge freight. More cargo was moved to the railway and by the 1890s the only regular trade on the Derwent was on its lower reaches. </p><p>By the beginning of the 20th century the river was being used for pleasure craft and by 1920 there were craft based regularly at Stamford Bridge and Kirkham Abbey. After floods in 1930 damaged the lock gates at Kirkham several vessels were stranded upstream. In 1935 statutory Right of Navigation was revoked above Sutton Lock.<sup id="cite_ref-Jones_7-3" class="reference"><a href="#cite_note-Jones-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> There followed a long series of fights for public access against riparian interests which continue to the present day. </p> <div class="mw-heading mw-heading2"><h2 id="Economy">Economy</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=River_Derwent,_Yorkshire&action=edit&section=8" title="Edit section: Economy"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The economic profile of the River Derwent is dominated by its value as a water resource with the Derwent supplying Leeds, Hull, York and Scarborough as well as agricultural holdings along its course.
