Major fish rescue on the River Mole:: After the river dried up near Dorking thru Mole Gap .. water in isolated pools >28°C & oxygen hit 30% the EnvAgency, with RiverMoleRiverWatch & local anglers, saved hundreds of fish—inc 5lb pike & 3lb chub—relocating them upstream to healthier flow.

Combined snow & rain events make it difficult to predict river flow, as the melt can result in a sudden increase - the Mole flow rate at Gatwick is now approaching 8m3/s which pretty high!

(Thanks to #RiverMoleRiverWatch for the info)

This is the area affected by the warning 👇

A video update on our water testing results from November... thanks @sirgeogy.bsky.social!

I've know for a long time how good volunteering is for you..

Especially when it gets you outdoors, meeting like-minded films, doing some science, and really starting to make a difference on an issue that matters.

Everyone should have a go!

Posing with the whale on the #MarchForCleanWater last weekend 😁 Thanks to #RiverMoleRiverWatch for the amazing banner and fishes!

👏 Well done to #RiverMoleRiverWatch for your outstanding work this year. Just back from a v successful AGM. Great speakers, clear (& mercifully rapid) trustee reporting, tea on tap, & a walk with picnic by the river. 🏞️

This is super, Simon. I’ve followed them all. Not sure I’m a river hero but do add me if you’re including #rivermoleriverwatch volunteers. 🙋‍♀️

Great to catch up with everyone & thanks for topping up our reagents & for the fantastic new leaflets. 👍

And the last one is ammonia (NH3-N). Today it’s 0.14ppm.

Nitrate next. This one is done on a marine detector and has 20% NaCl solution added. There’s also a factor applied to the results. For now the reading is 18.7ppm.

Phosphate results in - 0.68ppm

Back indoors. Next job is to check the storm discharge map provided by Thames Water to see if sewage has been released in this stretch in the last 48hrs. And the results are… phew.

Sample taken. Heading back inside to complete the testing. All across the catchment this weekend we will be measuring ammonia, phosphate and nitrate by colorimeter.

River Mole looking pretty murky today. And running fast for this section. Floating pennywort, an invasive plant, is back and spreading.
