Every time I'm under my car (any) I clear any drain holes with a coathanger.
In your case, was muddy/brown water coming out, or just clear-ish water?
Easiest thing to do would be to scoop as much crud out with your hand and then try to rinse the rest out with careful application of the garden hose.
Fill with water, stir (to get the dirt up off the bottom of the door) then drain.
Then dry it out with a hair dryer/heat gun if you really feel like it.
