Knotford Nook Gravel Workings is an access point on the River Wharfe, noted in fisheries surveys of the Otley Angling Club stretch. The site includes a short layby that provides bankside access to the river.

The location has been identified as a conservation concern due to a significant stand of Japanese knotweed established along the bank, an invasive species likely introduced through fly-tipped garden waste deposited at the end of the layby.

The combination of informal vehicle access and dumped material has contributed to the spread of this problematic plant directly to the water's edge, posing a risk to the riparian habitat and native vegetation along this stretch of the Wharfe.
