There are gage stations, both at Tuscaloosa and Cordova, 

 Ala., where systematic discharge measurements have been made, 

 the results of which are given in the foregoing pages. Com- 

 parative measurements at the two stations at same stage, which 

 was same stage as low water in November, 1901, shows a. dis- 

 charge of 825 second-feet at Tuscaloosa, and 285 second-feet 

 at Cordova. At minimum stage of dryest years the water gets 

 considerably lower, as is shown by the records referred to, but 

 the figures named are safe for low season in all ordinary years, 

 and will be used in this discussion, for determining the power 

 available at different sites along the river. 



The locks and proposed locks on this section of the river be- 

 gin with No. i, at Tuscaloosa, and are numbered up the river. 

 Locks i, 2, 3 and 4 are about completed, and others are pro- 

 jected, but the locations of the latter in the following list are 

 approximated. However, the exact location of each is imma- 

 terial in showing the power available. The following is a table 

 showing positions of locks and lock sites in miles above Tusca- 

 loosa, the sea level elevation of water below each, the lift at each 

 and the net horsepower that can be developed at each day on an 

 80 per cent, turbine during dry season in ordinary years, like 

 1900, after deducting TOO second-feet for lockage.
