Three Sumps Spring History
Three Sumps Spring History
Ancient History, Farming and Engineering works.
The central sump of the stream, which is diverted subsurface, north from here, then surface to sump three and subsurface to the Lake Grounds, above Portishead path, showing its Age and spread back to the original inclination seaward to the Cliff. The whole site is awash in wet weather. South is the Hole in One, incised valley, with full stream, to the beach. Sump one is across Nore Road to the east, below Portishead Down, lower north slope. All sandstone, marl and quality soils that used quantities of fertilizer application and produced acres of barley, above the Conglomerate cliff base. I believe this may be an old landslide toward the north west over fragmented rock regolith sloping south, of older Geology, added to by soil slip and forest removal upslope and agricultural history, as well as the many spring seeps, but the base regolith is well drained, so the water is surface retained. Skylark once used this ditch hedgerow, for years as a nest site.
