Knotford Nook Gravel Workings is an access point on the River Wharfe near Otley in West Yorkshire, situated immediately south of the river and north of the A659 Pool Road.

The site comprises two open water bodies formed from former gravel pits, created after glacial deposits of sand and gravel were extracted from the Lower Wharfedale area. The old Pool Road bisects the site, which is fenced.

The lakes are managed primarily for fishing, and general public access is limited.

A short layby provides riverside access, though the site has been noted for issues including fly-tipped garden waste and an established stand of invasive Japanese knotweed along the bank edge.

Knotford Nook is recognised as a Local Wildlife Site and is listed among Otley's most significant natural heritage locations within the Otley Neighbourhood Plan.
