A 460&nbsp;mm bore was drilled through the base of the shaft in 1946 and plain lining (depth unknown) was inserted.<\/p>\n\n\n\n<p>The well was constructed for a domestic water supply and is regularly pumped.<\/p>\n\n\n\n<p>A borehole was drilled 10&nbsp;m from the well in 1990.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Hydrograph response<\/h3>\n\n\n\n<p>The hydrograph has a broadly sinusoidal appearance, with an absolute recorded range of 14.8&nbsp;m, although annuual fluctuations are typically around 7&nbsp;m. The groundwater levels at Dalton Holme respond relatively slowly to rainfall, perhaps influenced by the drift cover.<\/p>\n\n\n\n<p>The minimum recorded level is 9.64&nbsp;m AOD, on 14 February 1992, and the maximum recorded water level is 23.82&nbsp;m AOD on 30 March 1947. There does appear to be some constraint in both minima and maxima. As the well neither dries up nor overflows, this implies some regional stratigraphical control on levels.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Data issues<\/h3>\n\n\n\n<p>Weekly levels were measured from 1889. A chart recorder was fitted in 1977 and continuous digital recording started in 1986.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">References<\/h3>\n\n\n\n<p><br>Finch, J, Marsh, T, and McKenzie, A A. 2007.\u00a0<a href=\"https:\/\/nora.nerc.ac.uk\/id\/eprint\/1387\/\" target=\"_blank\" rel=\"noreferrer noopener\"><a href=\"http:\/\/nora.nerc.ac.uk\/1387\/\" target=\"_blank\" rel=\"noreferrer noopener\">A preliminary risk assessment of the potential for groundwater flooding during the winter of 2007\/8 \u2014 an update<\/a><\/a>.
