Top dam nearly full!

Just over 18 months since it was cleaned out and expanded, the ‘top’ dam near the house is nearly full. The new dam wall is a metre higher than it was so water is now diverted to a spillway at the south east corner of the dam. IF we have more decent rain in the next few days, I expect the spillway to fill!

Pumping the last water out before earthworks could begin

You can see from the above photo how shallow the dam was. It dried up nearly every Summer due to evaporation. Something needed to be done.

You can see the scale of the excavations when you notice the people on the new dam bank! How deep did we go? It was Dec 2017 so I’m frankly a bit fuzzy, but I reckon it must have been close to 6 metres.

We’ve had a little more rain since I took that photo so the water is right at the lip of the spillway. The local wood ducks are loving it! Once the water is in the 20m long spillway, I guess I’ll pull on rubber boots and go out with a mattock to fine tune the levels in the spillway. The plan is for the spillway to fill uniformly to a depth of 100 mm then overflow gently to the downhill side.
