Gunthwaite Dam sits along Gunthwaite Lane near Upper Denby, south of Huddersfield, and serves as the access point for Gunthwaite Park Fishery, managed by Slaithwaite and District Angling Club since 2010.

The site is reached via the A629 toward Penistone, then Denby Lane, with the fishery entrance found at a sharp left-hand bend just past a railway bridge. A small car park is provided on site, and anglers follow a gated path down to the water.
