GEOLOGICAL SURVEY OF ALABAMA. 



Minimum monthly discharge of Tombigbee River at Epes, Ala., with 

 corresponding net horse power per foot of fall on a water wheel 

 realizing 80 per cent, of the theoretical power. 



[Drainage area, 8,830 square miles.] 



NOTE To find the minimum net horse power available at a shoal 

 on this stream, near this station, for any month, multiply the total 

 fall of the shoal by the "net H. P. per foot of fall" in this table for 

 that month. 



3. TRIBUTARIES. 



There are several large creeks in Marion and Lamar Counties 

 that flow into Mississippi, and enter the Tombigbee River near 

 Columbus. One of these, the Buttahatchee Creek, in Marion 

 County, has numerous rapids, especially near the crossing of the 

 Military Road. 



Luxapalila Creek, in Lamar County, has two prongs that are 

 both good power streams. They come together before the creek 

 enters Mississippi, making Big Luxapalila Creek, which enters 

 the Tombigbee at Columbus, Miss. The following measure- 

 ments have been made on this stream at Columbus, Miss. : 



1901. 



March 11 Gage height, 8.20 feet; discharge, 2,459 second-feet. 

 April 16 Gage height, 4.45 feet; discharge, 873 second-feet. 

 June 26 Gage height, 1.90 feet; discharge, 109 second-feet. 

 Oct. 31 Gage height, 2.00 feet; discharge, 126 second-feet.
