==Flood prevention==
Skipton suffered from flooding in 1908, 1979, 1982, 2000, 2004 and 2007. High volumes of water enter the town from Eller Beck from the north and Waller Hill Beck from the east. Both are culverted in the town, and Eller Beck is prone to carrying woody debris from Skipton Woods into the culverts, causing blockages.{{sfn |Environment Agency |2014 |p=2}} A Skipton Flood Alleviation Scheme was developed by the [[Environment Agency]], which would cost an estimated £9.7 million to implement. The three component parts are a flood storage reservoir on Eller Beck, to the north of the A65 road, a similar structure on the Waller Hill Beck, and the construction of flood walls at strategic points in the town.<ref>{{cite news |url=http://www.cravenherald.co.uk/news/10939126.Permission_sought_for_flood_storage_reservoir_at_Eller_Beck__Skipton/ |archive-url=https://web.archive.org/web/20210102165323/https://www.cravenherald.co.uk/news/10939126.permission-sought-for-flood-storage-reservoir-at-eller-beck-skipton/ |archive-date=2 January 2021 |url-status=live |title=Permission sought for flood storage reservoir at Eller Beck, Skipton |work=Craven Herald and Pioneer |last=Anon |date=21 January 2014|accessdate=26 September 2014}}</ref>
 
The Eller Beck storage reservoir will have an earth dam, {{convert|355|yd|m}} long and a maximum height of {{convert|46|ft|m}}. It will be {{convert|13|ft|m|0}} wide at the crest, and contain {{convert|124000|cuyd|m3}} of material. It will enable the storage of a maximum of {{convert|15.3|e6cuft|Ml}} of flood water. A {{convert|100|yd|m|adj=on}} culvert through the dam will carry normal river flows. The bottom of the culvert will have baffles to retain materials and create a low-flow channel to aid fish migration. Flows up to {{convert|600|cuft/s|m3/s}} will not be restricted, but greater flows will be limited by a control structure, so that the excess water will be stored in the reservoir.{{sfn |Environment Agency |2014 |p=6}} Material for construction of the dam will be obtained from a pit near the reservoir on Waller Hill Beck, and transported along the A65.{{sfn |Environment Agency |2014 |pp=32–33}} One of the main objectors to the scheme was the golf club, where the 16th and 17th holes would have to be moved, and three other holes would be flooded when the flood gate is closed.{{sfn |Environment Agency |2014 |p=17}} Following consultation, agreement was reached on how the golf course would be remodelled.{{sfn |Environment Agency |2014 |p=13}} Within the town, three sections of flood wall will be built along the banks of Eller Beck. At Morrisons open culvert, to the north of the underground culvert beneath the carpark, {{convert|50|yd|m}} of wall with a maximum height of {{convert|2|ft|m|1}} will be built on the left bank, and on the right bank, there will be {{convert|32|yd|m}} of wall with a maximum height of {{convert|4.3|ft|m}}. Another {{convert|16|yd|m|adj=on}} wall will be built on the right bank of the beck immediately above the Coach Street culvert.{{sfn|Arup|2013|pp=8–9}}
