Growing ponds

Friday, July 27th, 2012

Continuing the water storage theme, the bottom ponds have expanded again. We have yet to fill the top ponds – there hasn’t been enough water coming down the stream to do so without compromising the water supply for our neighbours further downstream. This small expansion of about 1,000 litres’ capacity gives us a much deeper section to the top pond, as well as increasing the amount of bank in contact with water and allowing us to extend the growing area. It also potentially allows us to take water further along the terrace once this dry spell is over and we have an adequate flow of water again.

More ponds … and drought

Thursday, February 23rd, 2012

Back in October last year, I began an experiment in pond building. As I wrote then, it’s part of a strategy to retain water for longer in its passage through the quinta. Not just for irrigation purposes, but to increase the range of environments we have for growing and to support a greater diversity of wildlife.

But the ponds are rapidly becoming part of a developing long-term drought mitigation strategy as well. There are evidently years of severe drought here once every decade or so and at the moment it looks very much like that cycle is about to deliver another challenging year.

Pond expansion

Wednesday, November 30th, 2011

As mentioned at the end of the recent post on the ponds, I wanted to make the top pond larger and deeper to provide more variety in aquatic environment and a larger area of water around and in which to grow. It’s now twice the size it was, with an area twice the depth.

I have been thinking for a while now about ways to retain water for longer in its passage through the quinta. Not just for irrigation purposes, but to increase the range of environments we have for growing and to support a greater diversity of wildlife. The extent to which we can emulate strategies like Sepp Holzer’s at the Krameterhof and Tamera is constrained by the vastly smaller amount of land we have to work with, not to mention the topography and difficulty of access, but even on a much smaller scale, the principles ought to be similar.
