We use a pretty simple analysis in the singing world... "Pee clear, sing clear." Basically, you should be urinating quite a few times per day, enough so each time, save for possibly the first thing in the morning, it runs clear.
Physiologically, I'm not positive that this is true for every person. I know in my experience, I can be urinating clear every 45 minutes, and still feel slightly dehydrated, and have a dry.
If you're training for athletics, especially distance athletics and ESPECIALLY if it's your first time, you should be very careful, and consult a doctor, trainer o mouth r nutritionist. It's a fine line between not enough water, causing dehydration, and too much water, which can cause hyper-hydration, or water poisoning. Essentially, that's an imbalance in electrolytes hindering brain function, and possibly causing death. It almost always occurs in athletes training or running an endurance race while drinking only water, instead of replenishing electrolytes.
That said, the first saying is definitely a starting point.
The normal daily turnover of water in your system (for adults) is 5-10%. When you take into account how much of your body is made up of water, this is quite a bit. Some of it comes from foods you eat, even prepared foods, and some from other beverages such as juice or coffee. However never underestimate how much water your body needs.
I personally find I need to drink much more than the expected amount, even on days I don't have time to exercise. I usually have the 8 glasses a day recommendation done well before lunch. However, I've also noticed that my kidneys seem to turn over a very high rate.
I remember reading somewhere that healthy human kidneys can only process 1 liter of water per hour. So don't drink that much unless you're sweating a lot. I wish I could find the link right now...
The first signs are thrist,loss of appetite, dry skin, skin flushing ,dark colored urine, fatique, head rushes and chills. If the dehydrasion goes unabated, when fluid loss reaches %5, the symptoms are as follows:

Well, I know of dehydration causing you to become sick if you are in the ocean too long. I believe your body tries to "dilute the ocean", and in result your body loses its freshwater content to a point to where you will become dehydrated.
Loss of water from our body can lead to becoming dehydrated.
If you were to look at the microbiology aspect of the human body, high temperatures (above 105) do not allow all the proteins in your body to form correctly. Proteins in high temperatures start to denature or unfold and cannot perform properly. Not to mention that if you are exposed to high temps for a long period of time you would get extremely dehydrated. If you've been seriously dehydrated then you know how bad that can be.
caffiene is a diuretic, which increases urine production. this draws more water out yo body so u get dehydrated faster
