PINELLAS COUNTY. 
t 
LOCATION AND SURFACE FEATURES. 
Pinellas County lies on the Gulf Coast and includes the penin¬ 
sula between Tampa Bay and the Gulf of Mexico. The area of 
the land surface of the county is approximately 260 square miles. 
The surface is prevailingly level, with a gradual rise in passing 
inland from the coast. The county is crossed by the Atlantic 
Coast Line Railroad, and by the Tampa and Gulf Coast Railroad. 
The elevations recorded by the Atlantic Coast Line Railroad are 
as follows: Belleair, 49 feet; Clearwater, 29 feet; Dunedin, 13 
feet; Largo, 50 feet; St. Petersburg, 20 feet; Tarpon Springs, 14 
feet. 
WATER-BEARING FORMATIONS. 
The deep wells in Pinellas County doubtless terminate in the 
Vicksburg Limestone. 
AREA OF ARTESIAN FLOW. 
The flowing area, in this county, includes a narrow strip bor¬ 
dering the coast and extending somewhat north of Dunedin. Flow¬ 
ing wells can probably be obtained along the shore entirely around 
Tampa Bay. The accompanying map shows the area in this 
county, in which it is believed that flowing wells can be obtained. 
LOCAL DETAILS. 
CLEARWATER. 
Clearwater is near the center of the county, from north to 
south. The city water supply, at Clearwater, is taken from a well 
250 feet deep. A second well, 270 feet deep, is held in reserve. 
Both wells are eight inches in diameter and are cased about 30 feet. 
When not in use the wells flow, but when either well is being
