Thames is well up and weirs are fully drawn. Maybe TonyDunkley is right about the lack of dredging. It makes sense. Big floods last winter and now at the first sign of rain everything open and levels up. Predictable I guess. I still think Jim has things right. Living by an upstream contributor to the Thames, places that used to be marsh for 6 months a year are now either built upon or very carefully 'managed' Nature reserves (including one lake that has had to have 'oxygenators' installed), excess/unwanted water is fed into the Thames asap during times of heavy rain. If only it was dredging and too many houses with paved gardens. Then we might stand a chance. It's hot air, holds lots more water, what gets picked up across the atlantic drops out on us. It's not that I disagree with dredging, it needs to be done, for navigation purposes. It will have some effect on flooding too.

Ah - I see it's been raining a bit in Englandland? "It was showing no steam warnings earlier in the day on the Thames, but the level went up significantly today at Abingdon." You should be unchuffed! Have now included the R-sole.

The entire length of the Thames is currently on stong steam red boards.

For much of my childhood they would be marsh in winter and dry in summer, now the water levels are maintained at the same level throughout the year by man made features - so much for nature!

. . . . . . . . . . Big floods last winter and now at the first sign of rain everything open and levels up. Not quite everything, . . if you include the 'closed' minds of the gullible masses who have swallowed all the EA originated piffle about the effects of global warming, annual 'once in a 100 years' floods, and too many paved over driveways preventing rainwater from soaking into the ground. My conclusions regarding the effects of consigning maintenance dredging to museum exhibits and history are gained from precisely six decades of close involvement with and observation of the behaviour of river navigations in flood. The changes in behaviour of those river navigations in flood are all confined to the last twenty or so of those sixty years, . . in other words, all post the cessation of routine maintenance dredging, and are especially marked in the increased period of time it now takes floodwater - in the form of measured river level rises - to progress downriver in the early stages of a flooding event, and the even more extended period of time it now takes for the last of the floodwater to run down out of the upper reaches of rivers and river navigations in the final stages of a flooding event. The inescapable, and only evidence based conclusion to be drawn from these long term factual observations is that it now takes far longer than it used to for any given volume of water to cover the same distance along the courses of the now un-dredged for 20(+) years rivers.

Reported today, warmest ever September, globally. Warm air holds more water, water drops out of sky, flooding on a scale rarely seen before happens. E.g. Last weeks storm hit France .5m rain in a day several drownded.. Co-incidentally, this has been getting worse for the last 20 years or so. Still need to dredge but it won't save us.

Watching one of the news videos that France thing does seem slightly rude. www.bbc.co.uk/news/world-europe-54402096I don't have telly and don't really follow the news so not seen any of these images before. I would be a little miffed if this sort of thing happened where my boat is. It could get a little discombobulating.
