Recommended lures

Nymphs: Small Hare and Copper, Pheasants Tail variants and any small straggly looking nymph in small sizes (size 14 -  16 preferred) work well. Some weight may be required in the deeper and faster sections. Dark coloured flies are more effective in this water.

Dry flies: Small winged patterns such as Greenwell's Glory, March Brown or Adams  are all effective. Green Beetles are effective in early summer and Cicada patterns from late summer.

Wet flies: Small wet flies such as March Brown, Greenwell's Glory or sedge emerger patterns patterns work well throughout the days when fished under the ample vegetation and are particularly effective in the evening rise.

Spinners: Small bladed spinners such as Veltic or Mepps.
