I was pleased with the Lasagne until it rained! It became clear that once the mulch, straw, manure and green waste had become saturated with rain then the water began to move! As the Wet Season descended on us the rain caused the water to seep, with all its soil regenerating goodness, from under the lowest point - near the letterbox - and then down the road!
Action was then needed. Checked out Bill Mollison's book and then went about installing swales.
I made up a frame to get the contour levels correct. I was surprised how easy this was. This technique was demonstrated at my Permaculture Design Certificate course. All I had to do was pivot it from end to end and find the next point where my spirit level said it was level! (Alternatively I could have had a plumb bob hanging by string from the top and locating with a mark on the base board that indicated it was level) By doing this the two trenches I made are level and hence store the water rather than have it run one way or the other. (In one image you can see the trench filling as I was forming it.)
