I am going to be fishing a local Reservoir pretty often, my question is what kind of lures should I use on this Reservoir.  It is 4000 acre Reservoir with water anywhere between fairly clear to murky it has some stumos and some rock bluffs near the dam and some steep dropping shore lines.  I will be fishing from 4 in the morning to about 12 in the afternoon.

i think you are going to need to be much more specific if you want to get good advice.  what you have described is so broad that you could potentially throw anything.

I would start with a buzzbait in the morning around the cover and switch to working a crankbait or a spinnerbait around the stumps after the sun got up a little.  More info would be a big help but this would be a good start.

I would also start on a buzz bait in the morning. A good rule that I always use is cast about 20 times in the general area and if nothing, move to another spot. In the shelves try using a s-carolina senko,  fat ika, or grub t-rigged. The spinnerbaits and cranks are a little bit easier to hang up on stumps etc when you are trying to explore. If you are fishing a wide area and lots of places the spinnerbait with a white/chartreuse skirt will cover lots of area. Fish the soft baits slow.

I WOULD START WITH STUDYING THE SEASONAL PATTERNS OF THE BASS AND TAKE IT FROM THERE.no sense throwing  something inappropriate to whatever pattern they are in.by now they would be in a summer pattern so other than early morning or night your topwater patterns may be short lived depending on how hot it is when you are fishing.hot summer weather will cause them to bury under thick weed matts real deep if you have them in your reservoir.if not then docks with deep water might be the ticket.i'm not saying you won't find fish shallow but deep is usually better.
