This isn't strictly reservoirs, but I noticed today that the water levels on
my local nature reserve are as high as I can ever remember seeing them. The reserve sits amid banks of pebbles and cobbles (piled up by longshore drift as the land has gradually risen over the last 10,000 years or so) which are easily permeable, so it looks as if groundwater levels must have risen sharply since the end of October 2003.

My only concern now is that much more rain will probably cause the stream
next to my house to burst its banks. Last time it flooded, the Warden Bay community centre was also flooded. Shaun Pudwell. "Anne Burgess" wrote in message ...

writes A few months ago the doom and gloom merchants were predicting droughts for Summer 2004 if rainfall totals weren't 20% above average by the end of January, etc. Okay, so it's not the end of Janauary yet, but how are we doing now on a local basis, ie north, south, east, west England, Wales, Scotland, etc? Are reservoir levels back up to what they should be, and if so where are/aren't they?

That's nice to know, Thanks. |

![]() " Rutland Water appeared to be nearly full, last Sunday. Check out the difference between reservoirs, which are generally reasonably full, and aquifers, which aren't full. Much of our water supplies comes from the latter and we need a wet spring to top them up. Alf King A good test of groundwater levels around here is where the River Ver starts to have water in it. Last winter it was flowing from Markyate which is close to the 'official' source. Currently it is dry until it reaches Redbourn golf course which is about 2 miles to the south so the replenishment of the groundwater levels has some way to go. I am sure this test could be applied to many chalk streams. Alan |

I went to the pumping station at the source of the Ver to arrange for a school visit so we could follow it to the Thames and then the sea. I also remember when there was too much water in the Ver and the old pipes were too small for the flow after a storm and some houses had floods of back-washed effluent three feet up their lounge walls. But I digress! Dave. -- Dave & Viv are living happily ever after in Pembrokeshire. http://www.daviv.com Videos of badgers and foxes on our patio and bluetits in their nestbox. |

![]() "Alan Gardiner" A good test of groundwater levels around here is where the River Ver starts to have water in it.

Currently it is dry until it reaches Redbourn golf course which is about 2 miles to the south so the replenishment of the groundwater levels has some way to go. I am sure this test could be applied to many chalk streams. How incredibly simple and effective. In my village of Great Chishill - seemingly the source of most of the water that subsequently flows into the North Sea - the gauge I use is how much of the road in the village is covered by the semi-permanent puddle. One winter, the local wag put up a sign "No Snorkelling". It is interesting that although this village is the highest in Cambridgeshire, it is incredibly soggy. My geologist wife tells me that the water table here is so high as the chalk squeezes the aquifer and forces the water out the top. I must say (going back to a much fitter youth) when I occasionally climbed up a mountain in Scotland, I was surprised to find that the ground seemed to be wetter (more boggy) the higher I went. I naively thought that water always flowed downhill. I don't understand much about hydrology so I have doubtless got hold of the wrong end of the stick somewhere. Jack |

Have a look at artesian wells, which work on that principle. -- Terry Harper http://www.terry.harper.btinternet.co.uk/ |

Unfortunately they follow the usual rule otherwise springs and artesian wells might be a hint as to how to get perpetual motion... Mike. |
