On November 10th 2008, after a period of heavy rain, much of the pathway at the bottom end of the Machine Pond was flooded, as the four photos below show.

Hopefully we won't have

flooded footpaths any more

as a newlarger overflow

 has been put in.

A new footpath

 was installed

The stepping stones over the stream would make walking from the Picnic Area to Machine Pond much easier.

A small dipping pond was formed next to the stepping stones.

On Thursday 5th the digger got firmly stuck in the Horsetail pond

 By Friday though everything was going well

....and the Horsetail pond was re-appearing.

The notice on the bank above the pond warns of "DEEP SOFT GROUND", I would call it DEEP STICKY MUD"!

The  Horsetail Pond had

been re-established,and to increase the depth, a

new dam has been built.

All the mud from the bottom of the pond had

been formed into a gently sloping bank. It looked

a mess, but when nature takes over, and with

the FPNYW helping by planting some appropriate greenery, it will be beautiful in a few years.

All this mud will form a path down to the dam where the stream can be crossed.

March 2009 - The Horsetail Pond is Scraped.

On 29th of April, Landcraft returned to repair the fault

Unfortunately it was not be a case of just "bridging the gap", or the problem would just appear further along the bank. We had to wait for the firm's recommendations and then work out the best way forward.

We were particularly anxious to get the water level back up before the waterfowl start nesting so that we didn't lose any eggs or chicks.

The new dam that was installed at the outlet of the Horsetail pond the previous Spring had been breached. The pressure from the ice and snow proved too much for the new structure, and when the thaw came, the water started to find its way around the edges.

After that, the channel got progressively deeper. That resulted in the water level of the pond dropping, so that it is was even lower than it was a year before.

To resolve the problem a meeting was held on site with a representative of Groundworks, the Contractors who worked on the Pond improvements the previous March.

We then  wanted lots of

rain to bring the water

 level back up

With more rocks in place, and a bank of  soil all stabilised with concrete, the dam was soon repaired.

With the dam intact, the Horsetail Pond was full and looking good.
