There's a resurgence at Holme, presumably fed by water sinking on Farleton Knott, that emits a large stream in wet weather; unfortunately it's located in somebody's garden.
Is the resurgence in question the one which comes out of a culvert next to the road, which can turn the normally dry stream bed in Holme into a raging torrent (see picture, taken in only moderate flow)? If so, we've investigated this a while back. We found a very helpful couple who live in Holme who introduced us to various other key householders (as the situation is not as simple as it first appears).
The house owner where the "main" resurgence is was kind enough to listen and consider our request for access but she decided she does not want cavers involved. However, further back (near the cricket ground) there is another short section of normally dry streambed. Downstream leads into a culvert which is probably the source of the water rising from the "main" resurgence culvert. At the upstream end is another dry culvert leading beneath a bungalow. The owner of the bungalow was really good with us and allowed a visit. We took the opportunity to make a sketch survey of this, which we named "Culvert No.1".
This is 9 m long and ends at a downwards choke, through which pebbles could be dropped into deep water, in an echoing area which looked natural; almost certainly a static sump pool chamber from which a large volume of water rises in flood. However the roof is supported by a slab, which is resting precariously on a smaller rock, which is resting on loose material. All this is very close to surface and is under the bungalow owner's property. Our assessment was that any interference would be likely to lead to collapse of the ground above, unfortunately.
I post all the above detail to save others the effort of going for a look and / or unnecessarily pestering the bungalow owner. If anyone is especially interested, contact me off board and I can let you have the sketch survey and a couple of photographs.
However . . . . there is a good possibility that the impressive amounts of water emerging at Holme in flood are actually coming from escape of water from the canal just behind the village, rather than from the great bulk of limestone forming Farleton Knott. Which would then beg the question as to where the true resurgence is? Quite a lot of ground water appears a bit further away at Holme Mills, for example (but perhaps not enough to account for Farleton Knott).
Really, this is a work in progress. We do have other irons in the fire but we aren't rushing and it depends to some extent on waiting for contacts to be made. We don't want to upset anybody and it's outside our main caving area, so locals aren't used to cavers' requests.
But - Fulk - maybe you were referring to a completely different resurgence altogether? In which case, please educate me! If it's in a garden, we may know an influential local who could help arrange a visit.
