Looks like I lost a few of them but considering it looked like a river running through them it was not too bad. The remaining ones are really taking off and doing good. A couple died almost all the way back but are starting to put on new leaves. I've even had several new ones sprout since the rain.

i guess if the drainage is good, the soaked soil dries out enough to allow the plant to spring back.

Good drainage is a must

Here is my acorn squash from about three weeks ago after very heavy rain. Today those leaves are back to normal, the plant is bigger, and has fruit growing now. (I cover up my vines to encourage more root formation and prevent SVB egg laying on main vines.)

So yes, they can recover from water dammage.

Looks like I will end up with 3 plants. Though that is perfect. We have gotten so much rain this year they have been underwater several times. These are the Atlantic Giant ones. My smaller ones and the Big Max were planted in a different area where they didn't get as much water running over them and they are growing like crazy. It looks like all the plants I have will produce really well.

You are supposed to grow pumpkin and squash on hills, for warm soil and better drainage. You can just mound the soil to make a small hills.

The problem is the garden is on a slope and we have been getting as much as 7" of rain at a time. With that much rain even on a slope it can't runoff fast enough. The pond has been overflowing for a couple months.

I recently learned (I think) that over-watering can cause leaves to wilt. It looks like water-starved...but is just the opposite, I believe. Still learning....Update: my moisture meter (around 6" deep) tells me the soil is "moist"...not dry...not wet. I am very confused about the mid-day wilting...
