Pipeman,its a lekke feeling to know youre going on holiday!Its a tricky qeustion,cause you have to keep all the conditions in mind!
Try to see if you could see small fry close to the bank,any small tilapia,baby bass,and try to match the seizes,depending on the tipe of stucture in the dam,you can maybee fish with a crankbait maybe a perch,baby bass,firetiger,bluegill colours,IF there isnt any grass,youll get hung up on!
Anoter option is a texas rigged fluke,works wonders in open waters,just let it sink give it a twitch now and agian,a nother good bait is a spinnerbait,white,yellow,natural with gold or silwer willow leaf blades,one tip(THE BIGGER THE BETTER) 1/2oz nothing smaller!
Try and target stucture,remember the big ones always sits in the best spot in the house,they boellie the smaller ones out,right next to the bank or at the end of a piece of timber closer to deep water!Rather try to get early to the water fish the morning session till about 10 a clock,spend the rest of the day with the wife and kids and go back to fish at 14:30 till dark!Ejoy it,hope you can use some of this!
