A Watery Grave?

My goodness, my goodness!
Stretch as I might, I'm not reaching air!
If only I can hold my breath until the water recedes!
Then, it'll be on to find the elusive garden gnome!
How did I get in this well casing anyway?
And why is the water so deep and cold?
The story continues . . .
At a snail's pace
