Bessy Beck Trout Fishery is a fly-fishing complex near Newbiggin-on-Lune, Cumbria, set in the Westmorland Dales countryside just off the A685 between Tebay and Kirkby Stephen.

The fishery comprises three lakes — Island Lake (approximately 2 acres), Heron Lake, and Mallard Lake (each around 1 acre) — with depths ranging from 4 to 11 feet.

The lakes are stocked from an on-site rearing facility with Triploid Rainbow trout and blue trout. All three lakes are fly-fishing only, with barbless or de-barbed hooks required.

The fishery can accommodate up to 30 anglers at a time and suits all ability levels. Permits are self-service and cash only, though online booking is also available. A current Environment Agency rod licence is required to fish.
