About Seiont, Gwyrfai and Llyfni Fishing Society, Llyn Padarn
Llyn Padarn is a glacially formed lake in Snowdonia, an example of a moraine dammed lake, and one of the largest natural lakes in Wales. The Passport gives its length as about 2 miles (3.2km), its area as about 240 acres and its greatest depth as 94 feet (29m). Brown trout are the resident species, and the Torgoch (Arctic char) normally lie in the deeper water; the Passport says a boat is needed to fish for char and to contact the Cwellyn Arms.
The society’s website calls it an excellent wild lake, prolific for wild browns from the start of the season, with ledgering the preferred early method, fly fishing productive from April and boat fishing the best way to enjoy it. It puts the best time for char at trolling from late June and maggot fishing from mid July. A ticket for this section also lets you fish any of the Seiont, Gwyrfai and Llyfni Fishing Society beats on the Passport; maps for all are provided on booking. Prawn fishing is prohibited and dogs are not allowed. The lake is the source of the Afon Rhythallt. It is booked through the Fishing Passport.
