A community organisation established to restore the flow to the upper River Ivel

The upper reaches of the River Ivel are dying.

The upper River Ivel is a perennial chalk stream, meaning it runs all year, supplied by groundwater in the chalk aquifer. In 2019 the river ran dry from its source at Ivel Springs to Radwell for the first time in living memory.

The RevIvel Association is made up of a committee that meets regularly and is supported by the Ivel Protection Association who are an association of angling clubs, Radwell Parish Meeting and North Herts District Council.

The Revivel Association is pleased to be part of the Chalk Aquifer Alliance, a network of chalk stream river groups campaigning for these precious environments.

The Chalk Aquifer Alliance (CAA) aim to  unite independent groups to protect our chalk streams.

RevIvel continue to be a part of the CAA working group and since the summer of 2020 the Chalk Aquifer Alliance have been able to present a series of talks pertinent to chalk streams and the challenges they face, thanks to the generosity of both Bury Water Meadows Group (who host the talks) and of each speaker

Each have been recorded and make a useful archive to dip into.

  • Because the upper reaches of the River Ivel are dying
  • Because Affinity Water is taking too much from the source of the river or from the aquifer
  • Because the growth in population cannot be supported by existing water and sewerage systems
  • To inform and educate – to raise awareness of what is happening
  • To tackle the problems and do something about them


  • Too much water is being taken out of the aquifer
  • Historically there was enough water flow to drive multiple mills along the river
  • There is not a single river in the UK that meets the Environment Agency’s own ‘Good’ environmental standard!
  • There are only about 250 chalk streams in the world, fewer than there are Blue Whales or Coral Reefs! And 85% of them are in the UK
  • If we do not change our habits there will be no water in the river, and none to drink!
