A piece of worm. a cricket, or a fly pattern called a Black ant.

Go to a fishing tackle shop i.e. Cabellas/ Bass pro shops. that specializes in fly gear and look for a device that looks like a short skinny eyelet about the same diameter as your fly line, the shank of this will have barbs equally spaced down the length.( No knot eyelet.)
Carefully insert the pointed end of the shank into the end of the fly line then holding the line in pair of pliers gently tap the eyelet down into the fly line until just the ring of the eyelet is showing. Here is another link on eBay

Check your property deed, Unless your property extends into the river, you may need to get permission from the land owner.

Even though it is legal to fish 2 rods at once, make sure you do not have to pay a fee for the second rod. Or you may get busted by fish and game.

Check your state regulations. In some states an immediate kill is required. The good news is that if the fish are eatable, there are no bag limits.

Are you sure you want to use a 1 ga. shotgun ? That is a punt gun, the bore of a # 1 is 1.669" and the kick from that thing requires the gun to be bolted to the boat.

Take a noisy boat out into the lake, and wait for them to jump into it.

You are better off using the vinyl color coded wire sold in automotive stores for this purpose. Older extension cords very often have a paper inner liner, which once the outer sheath gets a nick or crack, wicks water into into the cord , it goes without saying, if it is an old cord it may have a nick or scrape.

If you are going to use conduits to enclose the wires, you have 2 choices, either make sure they are completely waterproof so no water can ever get in , or fit the conduit with drain holes so no water ponds in the conduit.
Standing water in a conduit does bad things to wiring especially if you have a splice in there, which of course you should avoid anyway.

I might be a good idea to have a leash on that Kayak . If you get pitched out in any kind of wind a high floating kayak may drift downwind faster than you can swim.

Off San Diego Ca., an anchovy or sardine at whatever depth they were swimming at worked just fine.

I have been preaching about this for several years. If a motor is run constantly the Ethanol is a semi good thing, it will absorb any moisture in the fuel and cuts down on Co. However if the motor is not run for a week then it is the kiss of death, the alcohol will absorb moisture out of the air until it cannot hold any more, then you get phase separation , the water will drop out of the fuel and collect in the bottom of the fuel tank. If this stuff gets into the carb, the older aluminum carbs will react and produce a white oxide powder, combined with the water it make a white paste like salad dressing, this stuff gets into jets and blocks passageways on carbs causing rough running , mixture problems ,hard starting and other ills until it is cleaned out. The newer motors with sealed fuel systems and stainless steel float bowls do not have as much trouble but even they need to be cleaned out from time to time.

I was talking about a sit inside kayak . If you have a sit on top and you get rolled you will just get dumped in the water. Then you have to right the kayak and go cowboy fashion up the stern until you can get back into the seat. The point I am trying to make here is that you need to learn these self rescue techniques before you get out in the ocean or the middle of a large lake. and as Roaldo says wear a life jacket.

If you are going to fish from a Kayak There are two kinds of kayak paddlers , those who have rolled one , and those who are going to. Get instruction from an experienced Kayak paddler on how to do an Eskimo roll , this technique quickly brings the Kayak back upright and can save your life.

Since you live in Buford, go out along Buford Dam road and fish under the dam , be careful there because the army corps of engineers, does release water from Lake Lanier down the Chattahoochee. A rooster tail seems to work there , and remember these are hatchery trout.
