When my coolant tank suddenly read as empty, I filled it up and when I backed out saw a trail of fluid. It was NOT the overflow tube though. I see lots of dried coolant residue but cant find the source.. (car is 98 deville)

Water pump... look at belt on drivers side and follow down. Use a mirror to look behind the WP/crossover mount and I bet you see it leaking there. Not an uncommon occurrence and not very difficult to replace.

I think thats what it is.. The gray mass in the picture is just below and aft of the pulley. As soon as I turned on the car, drip drip drip all the way down. Looks like I got a project coming up!

Being it's a 98 it probably has the old style cover and the O Ring is know to leak(poor design) and was updated around 2000. If you are going to change the WP you may want to change the WP cover, it comes with cover, Oring, thermostat and new water outlet. Both mine were seeping fluid before I changed them(the cover that is).
Don't forget you will need a WP socket and righty Loosey for the pump... Use an AC Delco pump, amazon, Rockauto and ebay are your friend.
Here is pic of old vs new covers new cover number is : ACDelco 131-164

Awesome thank you. Can i put water in the car in the meantime until I get it fixed? It's my DD and its $$$ to have to put in a gallon of coolant every morning...

You shouldn't but IF you keep an eye on temp it MIGHT get you by for a few days.
As long as you're not going to run it all summer and fall on straight water you should be fine.
