How deep is the water?

A woman walks by a pond, and sees a beautiful flower growing on a stem in the middle of the pond. She finds a 5 foot stick by the pond, which just allows her to reach the flower and drag to the edge, where the flower just touches the water. She then picks the flower with 1 foot of the stem attached, and lets the rest float back to the centre of the pond. She notes that the freshly cut stem now just barely crests the top of the water.

Nope, but I should clarify the wording in the problem.

The distance from the edge of the pond to the flower is 5 feet, and the flower sticks out 1 foot above the surface of the water before being cut. You can assume that the flower stem is taught and remains a straight line from the flower to the centre-bottom of the pond at all times.

but I've never seen a pond with flowers growing in it that has banks that steep 🙂

The flower itself has no height? Just the stem.

It's a 5-12-13 triangle, so 12 ft.

Wrong, unless this is another trick question. One is only given that a flower with a 1 foot stem is growing out of the water, and is removed.

That's one possibility, but are there any others?

It's clear that it's a 5-D-(D+1) right triangle, but is 5-12-13 the only one of those?

No, the stem reaches to the bottom of the pond. Only one foot extends above the water.

5^2 + D^2 = (D+1)^2
25 + D^2 = D^2 + 2D + 1
2D = 24
D = 12

It's the only right triangle where the short side is 5 and the other sides have a difference of 1
