The usual practice at night is to fish the pool tails and deeper runs with a larger fly such as a Waddington or tube fly on either a full floating line or one with a sink tip, perhaps turning to a full sinking line later in the night. During any given night, changing tactics and using wake or surface flies is well worth a try. As with all fishing if the water is very low, the practised angler will drop fly sizes and use finer leaders.
Particularly when in pursuit of large wary Towy sewin the watchwords are stealth and quiet - a cautious approach is essential, both day and night.
