WATER SUPPLY OP PASTERN AND SOUTHERN PLORIDA. 245 
VALKARIA. 
A record of one deep well, at Valkaria, has been obtained. This 
well was drilled by Mr. W. J. Nesbitt, in 1892, for Mr. E. A. 
Svedelius. It is a 3-inch well, 350 feet deep, and is cased to a 
depth of 90 feet. The water is reported to rise 15 feet or more 
above the surface. At a depth of 320 feet hard rock was en¬ 
countered and, immediately below this rock, the first water, under 
sufficient pressure to cause it to rise to the surface, was obtained. 
ST. LUCIE COUNTY. 
LOCATION AND SURFACE FEATURES. 
St. Lucie County lies south of Brevard County. It is 42 miles 
long and from 24 to 42 miles in width. Et. Drum ridge in this 
county has an elevation of 66.74 feet above the mean sea level.* 
The eastern part of the county, aside irom the line of sand dunes 
near the coast, consists largely of palmetto flatwoods. Towards 
the west border the land is more rolling and numerous small lakes 
occur. Some muck lands are found near the headwaters of the 
St. Johns River. 
WATER-BEARING FORMATIONS. 
The wells of this county, as elsewhere along the East Coast, 
reach the Vicksburg Limestones. These limestones, however, dip 
in passing to the south and lie at a greater depth in St. Lucie 
County than in the adjoining counties to the north. The wells ofi 
the St. Lucie Ice Company, at Ft. Pierce, are 812 feet deep and, 
probably, reach the Vicksburg Limestone. The first flow from the 
wells, at Ft. Pierce, is reported to have been obtained from the 
depth of 725 to 750 feet. 
AREA OF ARTESIAN FLOW OF ST. LUCIE COUNTY. 
Owing to the few wells that have been drilled, the area of 
artesian flow in St. Lucie County is imperfectly determined.
