In cases of dam fishing, I think you have higher chance if you are fishing from a boat than on land. Then again, not everyone can deploy a boat. Try asking the locals around, type of fish, bait, etc. Where is this dam anyway? Looks like a rather nice place

Today I went with a friend scouting the river tributaries. But then, forgot check tide.

if you fish at a huge lake , i would suggest you bring bait that have strong smell

such as chicken intestine , since the lake is huge you might wanna consider feeding the fish at the same spot
for several days with fish pellet before you fish, just to attract the fish on the area to gather around

Get a big Milo tin,cucuk many many lobang, stuff with chicken intestine. Close it.. throw to the spot where u wanna cast.

Nice place you got there Sneaky Leaky.

If not mistaken, it's a direct river flow into it. Not a very big damn tho, approximately 700~800m line of sight. Dont mind to make a trip there.

possibility of toman very little, perhaps you may want to target sebarau or baung.

Bro SL,
Boat and thruster not a problem...

Now have to check with Bro Chun if he is keen to go..

bro try live frog...usually this dams are filled with haruans....dont believe try try.

Tie with line so you can retrieve it later or to adjust the position. Do remember to add some stones in the tin to prevent it from moving too far from the targeted position. Judge the amount of weight to put in depending on the current 

there's a difference between tightening the drag and keeping the line taut
general rule of thumb, set the drag to 1/3 of your line's breaking strain
eg, you're using 20lb line, set drag for just under 7lbs
need a handy dandy scale for that ... adjust drag accordingly until spool starts to turn around 7lbs
let the drag system do its job

reel drags work in tandem with rods
let the rod do its part by keeping the line taut as you hold it
rod can be used to turn the head of the fish from heading for cover

too tight a drag and your line could snap at any time when the fish runs
too loose and it'll go into cover
many tighten the drag, as the fish nears, to prevent the fish from making last minute desperate runs
this is a contributory factor to snapped lines and great frustration... so near and yet ...

lines are prone to snap also due to poor drags where the drag 'stutters' , ie not smooth
when the fish runs, hang on to rod and let drag do its work
when fish stops, lower rod and reel simultaneously
then pump, ie lift rod
then lower rod and reel ... repeat when fish has stopped until fish is landed 
this is where keeping the line taut as you reel is important, otherwise fish could shake off hook
have a fish friendly landing net handy ... trying to lift (big) fish out of water is a cause of broken rods

can you tell us what time you fishing ???

lol why you chose the hottest time in the day to fish........

try morning 6-10am instead ...

As I know pak so gong aka catfish do roam deep down to find food.but 18mtrs..I'm not sure..
BTW bro, speaking of 18mtrs depth  u sure ur sinker drop straight down bo? What size sinker u using?

yes, catfish are foragers
sinker size ... depends on baitfish size
say 3-3.5" lampam, carp or other baitfish ... those #1/2 sinkers with a metal loop or #4 oval sinkers is adequate
leader of approx 18-30" will allow the bait to swim freely
too long and it may lead to tangles ... hazards of the hobby
have to find out one way or another hehehehheh

bring along some sulfur if you're going at night
spread it around your spot to deter snakes
mosquito coil just in case
once you're used to night visits, can consider smelly bait
terrain familiarity + general idea of nocturnal visitors will give you an idea, since smelly bait also attracts monitors and snakes/cobras
oh yes, have a sturdy rod holder AND tie down the rod/reel ... just in case

i'm crazy enough to lay out 2-3 rods simultaneously
not because i want fish but i want action and to know what's available and what attracts
1 rod - earthworm
1 rod - baitfish
1 rod - seehum/shrimp/bread ...
i'll walk the edges with handline + earthworm for gobies 

What's ur rod rating again?
Just follow the sway.
Can try looking for these.

no worries, bro ... we all need to start somewhere
i understand how it is for newbies ... like when i haven't met my sifu yet
forum advantage: more heads are always better than one heheheheheh

the #3 sinker is good enough i think
the sinker aids your cast so you don't really need to power cast
which can sometimes cause you to lose your baitfish ... if it's hooked too thinly
let the rig hang down bout 1-1.5' from rod tip (individual preference)
open bail arm, place line on index finger tip
start from 2'o clock position behind you slightly off center to your right (if you're righty)
bring forward to bout 10o'clock with a gentle snap of your wrist simultaneously letting go off your index finger to release the line
once you're used to it, you can go for the 10-2-10 swing
my apologies if i'm being captain obvious ...
