45mins
Headed in expecting to find it diggable but with perhaps the pool before quite high, but we were wrong. It had rained extremely heavily over the last 48hours until Tuesday 5am-ish with around 1.5inches of rain falling in the area and all local river levels were up and many mini-streams flowing along the roads as drains or drainage channels couldn't cope. The end chamber was at least a metre deep above the hole in the floor, although the pool area was not up to the level of the grill, so this means that the water levels probably came up rather than flowed down, unless the pool has gained more of a leak at a level since previously!
We can only surmise that either this is water table level at this point in time - may be possible to verify with a comparison to the bore hole levels, or the hole in the floor ongoing passage is too small to cope with the recent rain (or possibly become blocked) or possibly that due to the proximity of the pond to the end of the dig, maybe there is an overspill level which enters the passage ahead of us and doing so faster than it can drain. This is all guess work, and hopefully by the time we are next back in the new year, we will have had enough dry days for it to have drained away again...
