Probably the biggest threat to any river system in the UK is #Heathrow’s disastrous proposals to build on top of, divert and merge 5 rivers for nearly 2km ...

Who wants to spend their precious weekend removing floating pennywort from a heavily infested section of the River Colne? Fortunately, this willing bunch of #volunteers do: they got stuck in on Saturday 18th July and did just that.

Do you want to know how much rain fell in the #Herts and North #London Area during #June or how high the river flows were? Here are the actual figures from the @envagency.bsky.social Pic shows River Chess, downstream of #Chesham town centre www.gov.uk/government/p...

If you find yourself in difficulty in water @london-fire.bsky.social advise use of the "float to live" approach. This technique, involves tilting the head back to submerge the ears, and spreading the arms and legs wide, while regaining control of breathing. www.bbc.co.uk/news/article...

How do ponds change over time? A new long-term research project from the University of Reading, in partnership with Froglife, is investigating how purpose-built ponds develop and continue to support amphibians and other wildlife years after they're created. Read more: https://ow.ly/TTnN50Zm2ts

While we make the most of the sunny weather, sadly the #heatwave is not ok for UK nature and wildlife: rivers get overheated and flows depleted, pollution even worse than usual. Don’t be tempted to swim where there could be hidden dangers including underwater hazards and pollution.

The Thames Catchment Community Eels Project would love you to take part in their Bring Back the Eel public consultation. Responses from anyone who cares about rivers and eels are genuinely valuable to @thamesriverstrust.bsky.social Survey takes around 5 minutes

#volunteers have done a fantastic job of surveying the River Pinn. It makes a huge difference having an organised programme like @zslofficial.bsky.social ’s Outfall Safari to build confidence and mobilise coordinated activities.
