Supporting Evidence
Photo of my evidence.
There was no flower floating around with the lily pads that we found.
Photo of my evidence.
The lily pads that were found, either had a spatterdock flower around them, or the lily pads had not been grouped big with their stems at the top of the water.
Photo of my evidence.
The lily pads that we did find, the stem was to thin to be the Yellow floating heart lily pads.

Comments

I agree, from what I see in your images, you've found Spatterdock.

Yeah, it's kindo of tough to I.D. lilies when there are few or no tell-tale flowers.

One quick clue to identifying yellow floating heart (YFH) against non-flowered native lilies is this: Each YFH stem supports a loosely branched group of SEVERAL leaves whereas all native heart-shaped floating leaved plants produce only one leaf per rooted stem. --Paul
