The concept of catching and storing water in the front yard wetland worked well from the start, but it needed some fine tuning. When the rains came back to fill up the depression I could see where high and low points were, so I leveled them out. Having a level area gives the water a greater surface area to soak into the ground. Ideally the water would soak in within 12 hours.
I blocked the inlet channel from the laneway with some minor earthworks to give the wetland a chance to dry out a bit. This is easily reversed if I want to bring more water in (and it rains). Extra soil was added to define the edge of the channel and stones used within it to reduce the boggyness.
