Thanks to RevIvel for an informative tour of the Ivel Springs this week.
One key takeaway: It's vital that excessive water abstraction from chalk stream source aquifers is reduced, to restore natural waterflow.
Healthy, flowing watercourses are critical for our wildlife, and indeed for ourselves.

Hi #freshwater folks 👋 The Freshwater Biological Association have announced a new initiative to assess one of our rarest fish, the Arctic charr, in Windermere.
There is a crowd funder, too, to support the work ☺️

So sad to see the water run off from roads and fields polluting the Vale Brook which flows into the River Chess in Chesham. Yes, that clear water above is what a chalk stream looks like, the rest is pollution.

Thameswater has been dumping sewage, no stop, into the River Ver , a chalk stream, for 2,146 hours.
89 and a half days.
The Ver is 1 of only 225 on the entire planet.

My most memorable Orca encounter ever was this sighting of the West Coast community Orcas John Coe and Aquarius from the Ullapool to Stornoway Ferry.
Sadly these 2 males are the only members of the pod left and given their age (60 years +) will not be with us too much longer

Highway runoff causes horrific pollution of rivers every time it rains. This outfall in Lancashire discharges toxic, hazardous substances into the River Lostock, causing it to fail to meet env. standards. These substances are toxic to the invertebrates living in the river. #StormwaterPollution
