One question is, is this the full level of the pond? or will it fill up more, that will submerge them even more? which will make a difference in their survival chances.
Good question. This is a new pond, dug last December, still filling up. Finish grading and grass planting was just completed. So, there is no history, yet. The high water mark was planned to be another two feet or so from the current level in the picture.
