With water flowing through it over a "washing floor" and the two fireplaces used for drying the linen. Or, a wheel and pin was used to drive machinery that substituted for my mother's paddle pounding of the linen. A prototype of a "washing machine"! And as you say, such machinery could have subsequently been removed and used elsewhere. As the water level of the river declined to make the original design inoperative. >> Perhaps this might have been the use of the 'cottage', but it would have required the management of the watercourse to obtain the necessary flow. Most watermills require similar management. However when the 'mill' goes out of the use the management of the water course tends to revert to its natural state. As I said before the state of the watercourse now, would be the state of the watercourse before management. If the quarry isn't in flood now it is unlikely that it was in flood in the Neolithic/Bronze Age.
