DRAINAGE OF BLACK AND BOGGY SWAMPS, S. C. 5 
The highways of the district are the usual dirt roads, but they have 
been improved recently by the county and are now in very good 
condition. 
WATERSHEDS. 
There are two distinct primary watershed areas in this district, 
drained respectively by Boggy Swamp and Black Swamp, which are 
in turn divided into various secondary watersheds drained by the 
tributary branches or swamps. In addition to the two main water- 
sheds with their tributaries there is included within the district a 
section of land in the vicinity of Garnett drained by Church Branch, 
Hog Branch, and King Branch. These branches flow down into the 
second level of overflowed lands bordering the Savannah River and 
form what is known as the " Pallachucolla Savannas/' which empty 
farther down into Black Swamp. Thus, while they are in reality 
tributaries of Black Swamp, they will require separate handling so 
far as this project is concerned. Similarly, Scott Swamp No. 1, 
south of Robertville, and two small areas farther west must be con- 
sidered separately. Black Swamp and its tributaries drain 18,490 
acres, Boggy Swamp and its tributaries drain 36,693 acres, and the 
independent watercourses drain 12,459 acres. 
These watershed areas are for the most part fairly rolling, although 
the portion of the district west of the Augusta Road and that part 
between Scotia and Garnett are quite flat. The higher and more 
rolling lands are cultivated to some extent at present, as they have 
very fair natural drainage, which is aided by some farm drainage; 
but even on those lands crops fail in wet years, showing the need of 
a general system of drainage. The swamps and the flatter areas are 
mostly covered with timber, which is being rapidly cut off by lumber 
companies. 
DRAINAGE CHANNELS. 
There is no lack of drainage channels in Black and Boggy Swamps 
district, yet drainage conditions are bad. The situation is due pri- 
marily to two causes — (1 ) lack of suitable drainage comiection between 
the wet, flat areas and the drainage channels or branches, and (2) 
the inability of the drainage channels to remove the water after it 
has reached them. The two main drainage channels for the district 
are Boggy Swamp and Black Swamp, the former serving the northern 
and western parts of the district, the latter serving the eastern part, 
and both finally emptying into the Savannah River, the outlet for 
all of the water from this district. There are numerous smaller 
branches or swamps tributary to these, which reach out to the differ- 
ent parts of the district, and which are the outlets for the drainage 
from their respective watersheds. A general description of these 
channels will suffice for this discussion, since they are all similar in 
character and differ only as to size.
