to me, it seems a bit logically absurd if they do. My main contention is that all other bodies of water are somehow interconnected and form a network. Thus, water can flow from an area of low tide to one of high tide. But a lake is bounded on all sies by land. For instance, lets assume there is no rainfall and no water evaporation. If there is a high tide in a lake,(even minimal...say 1 centimetre) how can the water level all around the lake, ie on all sides be increased by 1 centimetre if there is no extra water flowing in? Similarly, how can the water level go down at Low tide? Please throw some light on this.

The great Lakes do experience tides. When the tide rises beginning at the Eastern edge water is drawn from the West. As the Earth turns the high point moves West so the Eastern end has a low tide. Just like the Oceans. The average height over the entire surface still stays the same. Even land surfaces have some tidal action just to a much lower extent.
The effect of tides on lakes depends on size, if the lake is large enough it will have a measure able tide.

Edit: Read tim_ume's answer. Have one problem with it. Tides occur at all times of the day depending on the position off the Moon. The Moon can be directly overhead at mid-day not just morning and evening. You just see it better at night.

All bodies of water, even small ponds are influenced by tides which come from the influence of the gravitational pull of the sun and the moon. However even the largest lakes on earth experience such small tides the are hardly measurable(100ths of a CM) because even though large they are small as compared to the ocean. As for the level increasing on all sides this does not happen as one side of the earth is experiencing high tide the other is experiencing low tide. Look this up in any oceanography or most Earth sciences texts to explain even fuller.

i never really thought about it, but i see no reason why they shouldn't, since the moon's gravitational pull affects the ocean's tides. there would simply be not as big of a tide because lakes have less water than oceans and wouldn't build up as much momentum.
