One of the big reasons your body makes cholesterol is to take advantage of it's waxy texture to line the inner surface of your arteries in order to prevent water loss from your bloodstream when you are dehydrated. That way the blood volume is kept intact, though your blood pressure will rise.
However, if you stop being dehydrated because you regularly take in enough water each day, your body will then digest the cholesterol and clear your arteries automatically, and drop your blood pressure along with it. Even just drinking a couple of big glasses of water and then re-measuring your blood pressure will show it dropped significantly in a half-hour.
Dehydration is the big deal - cholesteral is just the emergency patch-up response that is supposed to be temporary.
