The lake is overlooked by the two static caravans, which can be rented out by visiting anglers during the season, and which have exclusive fishing of the lake on Mondays, Tuesdays, Thursdays and Fridays.
Fishing for season/day permit holders is therefore on Wednesdays, Saturdays and Sundays.
Frongoch is also the "social hub" for the Association, with anglers regularly meeting up to fish here, as well as hosting the Fur and Feather at the end of the season.
Parking for bank fishing is available in the "old quarry" at the south end of the lake with room enough for 3 vehicles. This parking just off the road makes Frongoch suitable for anglers seeking ease of access. There are also two parking spots for boat users.
The season at Frongoch runs from the 20th March until the 31st October (Having been extended for the first time during the 2022 season)
There are four boats moored on Frongoch (for boat permit holders) or caravan occupiers. These boats are easily powered by the provided oars, but are also suitable for electric outboards.
Fly fishing only.
The reservoir was originally constructed to supply water to the nearby mines which would have been used to power machinery. The nearby village of Trisant was built around the mining which bought industry to the area during the 1800s. The local area has a very rich mining history that stretches back well before the building of the dam here.
