The elevation of the surface of a lake is a good indication of the level of the water table at that location. Assuming that the elevation of a lake is half a contour interval lower than the contour line closest to the shore, determine the elevations of the following lakes.
The following questions are based on Map T-8, the “Putnam Hall, Florida” quadrangle (scale 1:24,000; contour interval 10 feet). This map shows a portion of northeastern Florida underlain by limestone 129°39'10"N, 81°57'15"W). Here the water table (the upper level of groundwater) is close to the surface.
(a) Slipper Lake _______ feet
(b) Lake Green Sills _______ feet
(c) Whirlwind Lake _______ feet
(d) Trotting Pond _______ feet
(e) Lake Lucy _______ feet
(f) Trout Lake _______ feet
Additional question:
1. Based on the lake levels, and noting the levels of other lakes and swamps, does it appear that the water table in this region is level or sloping? If sloping, in which direction?
(a) 95
(b) 95
(c) 85
(d) 85
(e) 85
(f) 75
