west, and enters Tampa Bay and the Myakka River, which flows 
to the south and enters Charlotte Harbor. It is probable that the 
northeastern part of the county, near the headwaters of these 
streams, reaches an elevation of 100 feet above sea. From this 
part of the county the elevation falls off gradually toward the 
coast. 
WATER-BEARING FORMATIONS. 
The deep wells of Manatee County are believed to enter the 
Vicksburg Limestone. The more shallow wells terminate in the 
sands and clays before reaching this formation. 
AREA OF ARTESIAN FLOW. 
Flowing artesian wells are obtained in Manatee County, along* 
the coast and, for some distance inland, along the Manatee and the 
Myakka Rivers and other streams. The flowing artesian wells, 
along the Manatee River, where a great many have been drilled, 
vary in depth from 200 to 600 feet. At Sarasota, on Sarasota 
Bay, flowing water is obtained at 360 feet. 
LOCAL DETAILS. 
BRADENTOWN. 
The city water supply at Bradentown is obtained from 
artesian wells, which vary in depth from 410 to 528 feet. The 
water from these wells will rise about thirteen feet above the 
surface, equivalent to a head of about twenty-nine feet above sea 
level. Numerous other wells have been drilled in and near 
Bradentown, which vary in depth from 200 to 600 feet. 
MANATEE. 
Numerous artesian wells have been drilled in and around 
Manatee for household use, irrigation and other purposes. The 
well of the Excelsior Ice Company, at this locality, is 540 feet 
deep, although a first flow was obtained at a depth of 360 feet. 
Mr. C. H. Davis has a four-and-one-half-inch well, 510 feet deep,.
