Flood gate

Flood gate

This photograph takes a little explaining. Bearing in mind that the view is foreshortened by virtue of the fact that a zoom lens is being used, we are looking along part of the fenceline marking the northern boundary of our property; it’s about 1.4 km (1500 yards) from the house. The fenceline crosses a creek at this point and although the creek is small it can rise dramatically in height and flow after heavy rainfall.

If a normal fenceline were to cross the creek at this point it would be damaged (or destroyed) by timber flowing down the creek in times of flood. To reduce the frequency of such damage, a more flexible fence is used. I drove several long star-posts into the creek bed, ran a couple of fence wires along the length to be fenced, and affixed the chickenwire securely to the top wire only. The chickenwire is loosely attached to the lower wire such that in times of flood the lower wire-ties will break easily under the pressure, the “gate” will pivot on the top wire, and debris flows (hopefully) freely under the chickenwire.

As flimsy as it looks, it’s seen a few floods – no doubt the “big one” will flatten the fence but it won’t take too long to repair it.

The bushes at either side of the “gate” are native “tea trees” (Leptospermum).
