I think my water pump failed?

Went riding with my buddy today in Rampart. Stopped and noticed my engine was covered with coolant and the radiator and cap were very cool but looked as though I lost most of my coolant. Has any one else had a water pump go down on them. I have an overflow tube running from under the cap, no fluid came from there. All the coolant was coming from a tube located right above my kickstart on my engine. So like I said, I think I lost my water pump, any other ideas by chance. And how would I check to make sure it is the water pump?
Thanks in advance. Oh yeah, it is an 87 KTM 350 Enduro.

Hey thanks guys, I am going through the whole system and going to replace seals, gaskets, and hoses as it is needed. The hoses are really soft so those are going to get replaced.
KTM-LEW, my dad and I got the forks all cleaned up and filled to proper levels. They worked great until this happened. The bad thing about the forks was there was 2-3 oz of oil in the right fork and very thin. The left was dirty, gunky, and at the wrong levels. But now it soaks up everything great. Now if I can just get the darn bike to stop breaking down after every ride I will be fine. Thanks again guys I will let you know how it all goes. Cheers
