Success with forming a pool in the wetland.

When we dug out the drainage ditch we put in a log to form a pool and make a small waterfall. The ides was to retain the water level so that water would be held to benefit The wetland plants that we intend to plant.
We only got one log in place as it was full of water and mud but it proved the principle and we will put three more in to make additional pools when it dries out.
