How can I make water showthe effects of a colored light?  i.e. fancy
fountains and such.  If I want to change the surface of the water I use a
plane just below it to show the light, but how do you make it show up on
water drops?

How about photons? Or the way I'd probably go about it is use a colour map
on the water and give the finish a high ambient setting.

Hope some of that helps.

Well, what you are usually seeing is highlights on the surface of the 
water and refracted images of the light source. Make a high ambient 
shape as the light source's look_like object, give the water some 
specular highlight and make sure the refraction is right and the 
max_trace level is high enough. If you still aren't satisfied, you could  
put an emitting media in the water to make the water itself glow. Or 
maybe scattering media if you have multiple colors of light sources.
