A feasibility and options report led to the selection of removal as a preferred option. Design of the removal option took place in Winter 2015/2016, and the removal process began in August 2016 (completing within one month). <br /> <br /> There were significant volumes of sediment that had accumulated behind the weir so the project had a strong element of hydromorphological restoration, as well as enabling fish passage. Any large stone located within the sediment was reused to create rock steps in the new channel, with the remainder being disposed of in line with waste regulations. These also acted as bed checks to guard against upstream incision, although in reality plentiful bedrock outcrops also served this purpose.<br /> <br /> A disused sluice gate downstream of the weir site was also removed to ensure effective fish passage.<br /> <br /> Finally, the left bank of the river channel is relatively steep and a public road is situated at the top of it. In order to stabilise this bank and guard against erosion, mixed seed-impregnated erosion protection matting has been installed.<br /> <br /> |Monitoring surveys and results=Removal took place relatively recently, and so monitoring has yet to be undertaken. Site visits are planned for early 2017, and in the longer term Galloway Fisheries Trust will carry out electrofishing surveys upstream of the site in order to compare the data with pre-works survey results.<br /> |Lessons learn=It was difficult to identify a cost-effective and reliable method of determining the original bed level beneath significant amount of stored sediment upstream of the weir. The final decision was to remove the sediment in a careful and 'staged' manner, ensuring that hydromorphological expertise was on site to determine the point at which the original bed level was reached. This made it difficult to estimate clear costs of sediment disposal, but estimates proved relatively reliable.<br /> }}<br /> {{Image gallery}}<br /> {{Case study image<br /> |File name=Creamery Weir.jpg<br /> }}<br /> {{Case study image<br /> |File name=Creamery Weir left bank.jpeg<br /> }}<br /> {{Case study image<br /> |File name=Creamery Weir from downstream.jpeg<br /> }}<br /> {{Case study image<br /> |File name=0125.JPG<br /> }}<br /> {{Case study image<br /> |File name=137.JPG<br /> }}<br /> {{Case study image<br /> |File name=0139.JPG<br /> }}<br /> {{Case study image<br /> |File name=1437.JPG<br /> }}<br /> {{Image gallery end}}<br /> {{Toggle button}}<br /> {{Toggle content start}}<br /> {{Case study subcatchment}}<br /> {{Site}}<br /> {{Project background<br /> |Project started=2014/09/01<br /> }}<br /> {{Motivations<br /> |Hydromorphological quality elements=Impassable barrier to migratory fish<br /> }}<br /> {{Measures<br /> |Bank and bed modifications measure=weir removal, <br /> }}<br /> {{Hydromorphological quality elements header}}<br /> {{End table}}<br /> {{Biological quality elements header}}<br /> {{End table}}<br /> {{Physico-chemical quality elements header}}<br /> {{End table}}<br /> {{Other responses header}}<br /> {{End table}}<br /> {{Monitoring documents}}<br /> {{Monitoring documents end}}<br /> {{Additional Documents}}<br /> {{Additional Documents end}}<br /> {{Additional links and references header}}<br /> {{Additional links and references footer}}<br /> {{Supplementary Information}}<br /> {{Toggle content end}}</div>
