That's today at noon, after 2 weeks with almost no rain. In the foreground, is the pool I dug out a little more on Sunday - as you can see it's filled nicely with water. I'd estimate it as being about 6-9in deep now, enough to sustain a frogspawn or tadpole population for a short time.
It rained a bit earlier this evening. More is forecast for tomorrow and for the Easter weekend. Whether frogs choose the pond as a nursery, and whether that's a wise choice, I have no idea and it's out of my hands now.
