I've come to the conclusion there are no water voles at present in the car park stretch of White Lion Meadow. This isn't especially significant: colonies do move about, up and down waterways, and if there's a breeding female outside the timber yard as the refreshed latrine suggests, then I'm sure there'll be voles back under the swimming pool stretch before too long (not least because they can't extend in the other direction due to a massive culvert)..
Meanwhile there's clearly activity elsewhere, despite the lack of sightings.
