Ty Mawr Beat, River Usk

River level

River level integration coming for this stretch.

The lowdown

  • This is club water, not a regular public day-ticket fishery. Access comes through Gwent Angling Society membership or by arranging fishing with the society.
  • Ty Mawr sits in the Usk Valley near Gilwern, in a properly scenic bit of Monmouthshire. Lovely setting, and a cracking river to spend a day beside.
  • The beat is mainly associated with quality wild brown trout. The club has also recorded trout catches from Ty Mawr in its annual meeting records.
  • The river has varied habitat suited to fly fishing. The society has used the beat for member fishing events and fly-casting clinics, so it clearly lends itself to a tidy bit of rivercraft.
  • A club article describes fishing a short 100-yard section of the beat. That’s the specific section mentioned, rather than a full peg count or detailed beat map.
  • Early-season fly life includes March Brown and Grannom hatches. Later, keep an eye out for Pale Watery, Blue-winged Olive, Yellow May, Iron Blue and Danica mayfly.
  • Fly fishing is the main thread here, backed up by the casting clinics held on the river. Read the glides, watch for a bit of colour and make the most of any hatch activity.
  • Salmon and sea trout opportunities are mentioned across the society’s Usk waters, but they depend on conditions and the regulations in force at the time.
  • The society is conservation-minded and encourages catch-and-release fishing. Some methods are restricted at particular times of year, so check the current club rules before setting off.
  • Water temperature matters. The society has suspended fishing on its beats during periods of excessive heat, so don’t assume the river is always open in hot weather.
  • We're not sure on ticket prices for this one — check with the club or local regulations before you leave.

Methods: Fly fishing is the obvious approach, especially around the named hatches and varied river habitat. Keep things light and mobile for the wild trout, while checking current rules before trying any other method.
