Martin is a beautiful lake first off.
It is a deep ledge lake that also has long shallow points in the river area and used to have some vegetation in the North end of it but it was not everywhere. Your location would put me in the backs of the creeks and here is why. That lake has a lot of shad. I don't recall if it has tilapia or blue herring in it but I do know it has a shitload of shad and they will be following the Bream to the backs of the creeks for the fall spawn. Remember they spawn twice a year and the heavy spawn will be in the fall. The bass will follow them all the way to the backs of those creeks. Look for shallow ledges (6-15 feet) adjacent to shad spawning beds. They look like pock marks and will be anywhere that has red clay or rocky transitional banks. The bigger bass will set up on those ledges and on secondary points in the back to middle of the creeks in my opinion. I have been on that lake a number of times and it isn't a difficult one to pattern because it is a deep clear lake. Find one fish and there are lots more right there. They school and have a large big spotted bass population.
First thing in the morning I recommend a pop-r or chug bug. If its windy throw a buzz bait and throw it three times to every target. Reason being is the fish type in that lake. Northern strain bass, Smallies, and big spots. They will track the bait if it is windy and are very aggressive as you probably know. Chug bugs have a rattle and a feather in them and will draw a fish to them. They are fished in a walk the dog retrieve. If you don't know how to do that, it is fairly easy to master. Cast it out and keep a bow in your line so that it isn't taut. Put the rod tip to the 8 oclock position with somewhat slack line, then with just a wrist action pop the rod tip back and forth about 18 inches so the slack is taken up only in the last couple of inches of movement. This will cause the bait to move side to side in a swimming action and is VERY effective.
Towards midday and in the evening I would have at least three crankbaits tied on or available. A couple of dt-16's and a DT-10. Get on those ledges and make sure your baits are hitting the bottom where the fish are. Long casts parallel to the bank on no more than 10 pound test. Use a palomar knot to tie them up with not a fishermans or blood knot as they decrease the action of the bait. Again, I can't stress enough how important it is to tick the bottom of the cover you are targeting on that lake. The fish come from a very long way to take a bait because of the water clarity. NOTE; If the wind is blowing and there is some chop on the water, doesn't have to be a lot, pick up a swim bait and throw the shit out of it, right down the ledge, slow retrieve. An Alabama rig or umbrella rig on that lake is awesome but they are expensive lures and require some time to get used to.
Mid afternoon you would find me looking for any isolated mussel or shell bed, or any isolated grass or rock piles in 12-18 feet of water. I would be throwing a weighted senko in the grass. Probably a 3/16 ounce texas rigged senko with the weight pegged on a slow popping type retrieve. Pop pop let it sink on slack line. Pop pop, let it sink. Carolina rig with a watermelon fluke on any other cover as well as the senko. If you find isolated cover, try to activate the fish first with a crank bait. Throw it from all angles until you get a bite. Have faith that the fish will be there. If you find an isolated rock or brush pile in 12 foot, there will be fish on it no matter what, you just have to get them excited and force them to bite because they will hold very tight to that cover.
Too make a very long story short, find a large creek arm and start at the back and fish your way out. They should be there or not far away. Fish every secondary point on the way out. Use shad colored baits (white and chartreuse. White and black or blue. Parrot color etc...) Watermelon red, and blue fleck plastics
Let me know how it goes, it's a great lake. Once you find them they will be doing the same thing all over the lake. Very pattern oriented lake.
Hope this helps,
