I have a fair amount of experience in fishing super clear waters. There is also much in print about fishing super clear waters via In-fisherman etc.

Much depends on your time of year but I will assume you are going june, july, august, sept. Argo is my idea of super clear water. I have found the less obtrusive your line is the more likely you can fool mr big. If big smallys are your goal and you are fishing plastics then I drop to 6 and often 4lb test. This means small hooks as large hooks are hard to tie and set with puny line. The straight tailed robo worms (4") on a 1/16 or 1/8 oz jig head is deadly. Of course conditions have to be right (as in fairly calm) and you need to know where they are. Bad searching tool unless you are patient, they will generally bite it if you put it in front of them.

The other equalizer is a jigging spoon. The erratic action will trigger a strike regardless the lb test. Again you need to know where they are.

If it is not to late in the summer a big topwater  will bring big fish up from depths as deep as 25ft. It needs to make a quite a mess on top to get their attention. Earlier in the summer smaller topwaters will take smallys. Topwater is a great way to fool a big fish in clear water.

As per walleyes I will stick with cranks tending to be long and run deep. I fish fast with them and run then primarily on 8lb test. Please avoid tying 8lb test to the split ring and get the little clips I advocate and use a tie-fast tool to tie a gryp knot. Clearly superior. 

Pike are still eating but tend to get  into a time pattern (eating during a slim and repetitive time window).later in the summer and typically eat something big and then hunker down. They are much like lake trout and are a cold water fish gravitating to preferred temps. Find a spring and you could be into pike city without having to fish deep to find cooler water.

Of course this is just my experience and can be poked full of all sorts of holes as fish will not always do what they have been told........

BTW......try slow rolling single blade dark single arm spinnerbaits in deeper water at night during summer. 25ft is about right. Hang on as they hit it really hard.......heavy line, no trailer, large black single colorado blade. Brown, black or deep purple skirt.
