if you know that they eat in a lake, matching the hatch is the way to go with clear water... always!!! consider when your fishery starts to get more stained (or muddy)... your water column you will be fishing will change with excessive stain moving to what we call chocolate milk (muddy)... the closer you get to "muddy" the shallower the fish will be and in most cases, the tighter to cover the fish will be... at that point, i use Chart/black or solid black with a good rattle... in "stained (1-2 ft visibility), i still like chart/black back but also i will try homer, citrus shad, and if it is more towards that 2 ft, i will even opt to the fire tiger... Either way... with visibility falling towards the muddy spectrum, it is never a bad idea to use a bait with a rattle or even opt to flat sided baits that push a lot of water. if that doesn't work for me... i try these same bait colors in a larger size to prompt a bigger presence and larger profile... if that doesn't work, i abandon crank baits all together and opt for a bigger / slower presentation... large profile soft plastics or bigger swim baits... I fish southern lakes in the Mississippi delta, and the above tips always work for me...
