The lie of the land is weakly uphill from the proposed moat only in a directly westerly direction and lidar fails us 200 metres from the henge in that direction. Contours  reveal no evidence of a depression that a stream would have created (anyway, people have looked for that before). A leet or stream from the north-west or the the north would have to cross a bit of a valley some 5 metres (at least) lower that the proposed moat so one would expect to see some evidence of the construction, even today.

I am reminded of the Roman baths in Bearsden. They show all the signs of 
being baths, they look like any other Roman bath I've seen, but then I 
realised there was one small problem.

The site is located on a promontory with no obvious way to supply 
running water and absolutely no indication of any ditch or other feature 
through which water would have reached the site. But again, on Barr hill 
- there are Roman "baths" and no possibility of a stream on the top of 
the hill.

Somehow the Romans managed to make water flow "up hill" and no one seems 
to be able to explain how they did this. Indeed, at a place like bar 
hill, if the water were carried up the hill in buckets, surely there 
must have been some kind of water storage - but if so where? The 
mechanics of moving water uphill appear to be missing from the 
archaeological record.

... so .... it seems to me that the druids must have had some magic that 
allowed water to flow uphill :)
