The new three-and-a-half acre trout lake opened at the end of March, since when over 1,700 rainbows and browns have been stocked.
Improvements have allowed stocking through the summer months.
The improvements involved taking the average depths from six feet to over 12 feet with the deepest areas around the sunken island being over 20 feet.
This island towards the north end of the lake provides an area from where many buzzer hatches occur.
The new lake has been landscaped with nine long fingers to give anglers good casting and enabling them to target fish in the centre of the lake.
Deep margins were added to aid safe fish release and minimize weed growth.
The lake has good clarity which enables the feeding trout to see their food clearly and help anglers to stalk and spot cruising fish.
The water inlet from the river has now been turned into a cascading waterfall with the water splashing down granite rocks to aid oxygen levels when lake top ups are required.
A recirculation pump is used at other times.
The trout are stocked in the 1lb 8oz to 2lb 8oz mark and are supplied by Bibury Trout Farm in the Cotswolds and are as hardest fighting as you can get.
The best rainbow to the end of August 2012 went 8lb 8oz with the biggest brown coming in at 6lb 12oz.
During the same period an average of just under 2.
5 fish per rod were taken.
Trout lake is stocked on a put and take basis, with levels at around 200 fish per acre.
Since the lake opened the most popular and successful patterns have been buzzers, diawl bachs, damsels, black pennel, black spiders, GRHE, corixa and bloodworms.
Sedge patterns and hoppers have also worked well on the surface.
Floating and intermediate lines with long leaders have shown to work best.
The new lake is an ideal venue for novice, improver or expert anglers due to its size and varying depths - not too daunting for the novice but large enough for the expert.
Anglers must kill their bag limit before any catch and release takes place and any fish taken must be shown to staff before leaving the fishery and recorded at the lodge.
Because of the depths close in there is strictly no wading allowed due and anglers are advised to wear an inflatable style waistcoat whilst fishing the venue.
Eye protection should also be worn.
Anglers fishing on a catch and release ticket are allowed three rainbows to be released after killing the bag limit of rainbows first.
All browns must be returned.
Catch and release anglers must use barbless flies only.
Anglers who do not want to keep their catch can take their fish to the lodge so they can be given to someone who wants fish for the table.
The fishery also allows fish over 2lbs 8oz to be released back into the lake.
