The frog pond in Autumn - with wellies!

We live on the edge of a large reservoir complex which has many interesting filter beds and water treatment tanks. Water is not treated locally any more so the beds and tanks have become wildlife havens. This tank has become a "frog pond" with hundreds of tadpoles and then frogs in spring. The water is kept pure and oxygenated by the healthy green pond weed which, as you can see, grows in abundance.
