Hello dave
heres what i know.
Gowna is really a maze of small lakes collectively called lough gowna.
for lough gowna the usual tactics for bream apply, prebait if
you can and bring lots of groundbait,hemp,corn,casters and
maggots (and throw in a pike rod too).
Dernafast:
easy access and parking by the amenity area,there are two lakes here
joined by a small river. the lake to the west has good bream in 6-10
feet of water over a stony bottom,there are tons of perch and roach
here too.
the east lake is shallower but produces good bream, fish are most
numerous at the two or three swims beside the stile and 30 yards to the right,the pegs over the bridge usually produce less.
Strettons shore:
get permission from the farmer mr.hall to cross his land.
the shore is of firm gravel and the lake bottom is also stony,fish close as there is a shelf close in that drops into 21 feet of
water,close to this shelf is usually the place to fish for bream,
100lbs bags should be achievable with heavy baiting.
Church lake (andys point)
access is through a gate with parking beside the lake.
fishing is in 12-17 feet of water for roach and bream,slider float being used most often.the better pegs are over the first stile and close to the second one
also try cloone lake for good fishing.
good luck
