Ground water records for St. Croix, U.S. Virgin Islands, 1969-1973

Ground-water levels at selected wells in St. Croix, the largest of three U.S. Virgin Islands, were monitored from 1969-73.

Monthly observations of instantaneous ground-mater levels were also made at two wells near Barren Spot and River Gut. Precipitation data from National Weather Service stations near the Mahogany, Airport, and Castle Coakley wells are shown with the water-level data.
