For the work party on Wednesday 23rd October, our main plan was start the construction of some 'leaky' dams. We've had problems in the past with water from the stream that runs down the valley flowing over the path by the tool store.
When I arrived for the work party the stream was well over the path and pouring out from the downstream end of the culvert pipe. There seemed to be a blockage in the pipe which I tried to remove, but with little success.
The other volunteers soon arrived and we set about solving our blockage problem. With some 'torch shining' up the pipe and some poking from the other end ...
... and a bit more poking with a bigger stick, the blockage was cleared. It turned out to be two tennis balls and a large lump of rock. The stream is now back to its normal course through the culvert and the path can dry out properly. We've installed a kind of grid over the pipe entrance which we hope will stop large items getting in. Fingers crossed!
We could now get on with the work we had planned to do. This was to start building some 'leaky dams' higher up the valley the stream flows down. A leaky dam is one of the methods used to help flooding problems. A leaky dam is built from the natural materials found in the woods and restricts, but doesn't stop, the water flow. We'd had looked previously for a suitable dam building site ...
... and thought that these two might well be suitable.
Erika and Eric are building the lower dam, Alan R and Alan W (I'm taking the photos) are having a go at the middle one ...
... while Peter and Graham are doing the upper section.
The main structure of the lower dam is near to completion...
... and the upper section is progressing well.
We had a tricky start this morning clearing the pipe which delayed the start of the dam building but we made really good progress. You could be forgiven for thinking that calling our structures dams is a bit pretentious as they are just piles of sticks, but dams are what they are. We will leave them for a while to let them settle in, then see how they are getting on and adjust them if needed.
