pass Lake, about four miles south of Bound Lake, is said to be 75 
feet lower or about 182 feet above sea level.* It is probable that 
the highest elevations within the county are found near Bound 
Lake. 
DRAINAGE. 
The Chattahoochee and Apalachicola Bivers on the east receive 
a great portion of the drainage of that part of the county. The 
Chipola Biver, flowing approximately through the center of the 
county from north to south together with its several tributary 
streams, drains the central part. A great many of these tributary 
streams are fed by springs /and in fact in some instances they take 
their source from large limestone springs. The drainage of the 
western part of the county is mostly into Holmes Creek and thence 
to the Choctawhatchee Biver. Alligator Creek is the principal 
stream in this section. 
In addition to the surface drainage a part of the drainage of 
this county is subterranean. The whole county as previously noted 
is dotted with many sink holes, ponds and natural bridges. These 
openings receive the surface waters which thus gain entrance to 
the permanent underground water supply. The blue or limestone 
springs are the natural outlets for the underground waters. 
AREA OF ARTESIAN FLOW. 
Two flowing artesian wells have been obtained at Graceville in 
the northwestern part of Jackson county. The flow in these wells 
is obtained at the depth of from 214 to 265 feet. The area in this 
part of the county over which artesian flow may be expected has 
not been determined as but few deep wells have been drilled.
