I feel a little like CH. I had a big cement mixing tub I was using to fill flower pots in (not with cement). It hasn't stopped raining since I started potting plants in it and it was in an area I couldn't dump it. I put mosquito dunks in it but by the time I get around to carting the water off to where it could be dumped, it was full of tadpoles. So I filtered it and got 24 tadpoles out of it that I now have in another container.
I'll probably have small toads and/or frogs by fall that I can release.
