The second ( larger ) creek on our property runs from a spring high up the hillside behind us and down the valley through our land. For years we had a lovely water feature - a pond ( or dam or small lake. ) One night in March almost 2 years ago their was a landslide which rushed down the valley and filled our dam with mud, trees, rocks and debris of all sorts. It ripped out many of the trees we had planted along the way. A real eyesore. Gradually it has softened as things have rotted and wild plants have overgrown other areas and we just left it to solidify. There was no chance of digging it out again; the expense and logistics being impossible. Since then the small stream has meandered where it likes across the area that used to be the dam, then under our bridge and on down the gully on it's way eventually to the sea. The outfall which goes under the bridge and down a spillway has to be kept clear or it builds up behind causing flooding which could if left unattended wash the access track across the dam ( to the avocado blocks ) away.
With yesterdays' high rainfall I feel Mother Nature might be trying to form a new dam for us. Certainly the creek bed will be more clearly defined now. We'll see what happens.
