We are planning to visit the Rivers Thames and Wey this spring and I have been planning our route. Part of this has been keeping a weather eye (!) on the river conditions.
After the weather we have had recently I suppose it's hardly suprising, but today all of the Environment Agency controlled Thames, apart from the reach above St John's Lock at Lechlade, is on Red Boards with no navigation!
I wonder if conditions will have improved later this month? Here's hoping - it has been a long winter with few local trips because of the heavy ice. From our experience on the Upper Thames after the floods in 2007 even navigation under Yellow Boards is not that easy, to say the least.
