Planted some Tall Fescue this weekend. I have been watering it for the
last 3 days lightly, 3 times a day (or as needed) @ 10 minutes. My
wife come home today around noon to check on some things and she cut
the sprinklers on for me but unfortunately forgot they were on and let
the water run for ~30 minutes-flooding certain areas of the lawn.
Should I simply wait it out and see what happens or is it a safe bet
that the seed is too water-logged and is now dead? Should I rake the
straw off the entire area (~2000sq.ft) and start over with new seed?
Frustrating. Its too early to tell whether or not the flooding hurt
because no grass has sprouted yet. However, Im afraid that if I wait
too long itll be too late to plant more seed. Grrrrr!

You're probably all right as long as you didn't have any gullys washed
out. Did the straw wash away? If not, I'd wait for it to germinate and
see if you have any areas that don't fill in. Better yet, seed is
relatively cheap. 2000 sq ft. Piece of cake. Just spread some more and
you will be sure. You can't get too much seed.
If you have water that stands long enough to drown the seed, you have
drainage problems that need to be addressed.

How long would water need to stand to kill the seeds? Also, I have red
GA clay soil, It has just been tilled twice, once in both directions
so Its somewhat "loose". Most of the time when I run my sprinklers (10
minutes) the soil gets good and wet but never muddy. I think its
draining ok but would need to have say, 2 15 minute waterings 30
minutes apart rather than one 30 minute watering. My wife said the
water was on for 35 minutes which caused the standing water. Absorbed
into the soil completely in about 3-4 hours. So, Im sure its not the
best drainage, nevertheless, not bad for the concrete they call soil
around here.
