The weir at Wetherby dates back to the 12th Century. It was severely damaged during the harsh winter of 1981, when part of it collapsed. A lack of enthusiasm for rebuilding it from local landowners and the authorities led to the creation of a new group - WWPT. They managed to raise £30,000 in three months to kickstart the reconstruction, which took place a year later. The group repaired the hole and some salmon steps which had also been damaged and then continued to restore the entire weir, which is now a key part of the Wharfe Riverside Walk. Their work also resulted in a wider riverside restoration scheme in the area.
The cog wheel was discovered in 1991 and restored. The WWPT was also responsible for building the bandstand next to the river - a popular haunt for those visiting the town during the summer months.
