46 GEOLOGICAL SURVEY OF ALABAMA. 



August i, 1900, to December 31, 1901, covering a record of 

 515 days, there were only 37 days in which the flow at Smith's 

 Bridge was less than 115 cubic feet per second. It is, there- 

 fore, plain that during the last two years such a plant would 

 have realized, for 90 per cent, of the time, not less than 800 

 net horse power continuously, 24 hours per day ; and that by 

 running u hours per day, 6 days per week, and storing the 

 water during the time that the wheels are standing, there 

 would have been 2,000 H. P. or more for use during factory 

 hours, for 90 per cent, of the time during the last two years. 

 By applying the rating table to the gage heights, and finding 

 the discharge for each individual day, the exact power obtain- 

 able can be calculated, due allowance being made for the stor- 

 age capacity, and equalizing effect of the dam. 



Of course, this 85 foot fall can be developed in other ways. 

 A low dam, and long canal can be used, or two separate 

 powers can be developed. 



6. HILLABEE CREEK, NEAR ALEXANDER CITY, ALABAMA. 



This station, which was established August 20, 1900, by J. 

 R. Hall, is located 6 l / 2 miles northeast off Alexander City, on 

 the road leading from that town to Newsite. The gage, which 

 is graduated to feet and tenths, arid is placed vertically, is in 

 two sections, the short section, which reads from o to 5.50 

 feet, being fastened to a post in the edge of the water on the 

 north bank 20 feet from the upstream side of the bridge, the 

 long section, which reads from 5.50 feet to 16 feet, being 

 fastened to the upstream end of the first pier on the north bank, 

 and arranged so that when water rises above the short section 

 the readings are made from the long one, both sections being 

 easily read from the north approach to the bridge. The initial 

 point of sounding is on the south side of the first pier on the 

 north bank. The gage is referred to a bench mark at the top 

 of a chord on the dawnstream side of the bridge at the second 

 pier from the north bank, and is 27.6 feet above the zero of the 

 gage. The bridge is in three spans, having a total length of 

 276 feet, with a north approach of 116 feet and a south ap- 

 proach of 124 feet, making a total, over all, of 516 feet. The 

 observer is J. H. Chisholm, a farmer, postoffice address Alex- 

 ander City, Ala. During 1900 the following measurements 

 were made by James R. Hall : 



August 29: Gage height, 1.40 feet; discharge 184 second-feet. 

 November 28: Gage height, 2 feet; discharge, 390 second-feet.
