Aii inspection of column A >h<\\> that some of the same fishes 

 arc present as in tin- uppermost pool of Hickory Creek. A-ain 

 there .ire certain dillerciiecs. These differences are the absence 

 of certain fish the Johnny darter, the golden shiner, the straw- 

 i-olored niinno\v and the common sucker. The presence of tlic-c 

 .it locality I. of Hickory Creek is probably due to the artificial 

 exposure of bare bottom.
