Winona Lake is one of the numerous lakelets found in northern In- 

 diana. It is located in Kosciusko County about one mile (l.G kilometers) 

 southeast of the city of Warsaw. Concerning the physical features of 

 the lake but little need be said as two hydrographic maps showing many 

 of these points, have been published; one by Large in 189G (Proc. Ind. 

 Acad. Sci., 1S9G) and another by Xorris in 1901 (Proc. Ind. Acad. Sci., 

 1901). The lake is irregular in ouUine and has an average length north 

 and south of al)out one and an eighth miles (1.8 kilometers) and an aver- 

 age widtli east and west of al>out seven-tendis of a mile (1.1 kilometers) 

 witli a large bay extending westward from the north end. It has an 

 area of about 0.9 of a square mile (2.3 square kilometers) and a maximum 

 depth of eighty-one feet (twenty-five meters). Two small creeks flow 

 into the southeastern portion of the lake and there are several large 

 springs along the east side. 



The data for this paper were collected at the Indiana University 

 Biological Station during the summer of 1901. I wish to acknowledge 

 my indebtedness to Dr. C. H. Eigenmann, Director of the Station, for 

 many courtesies shoAvn me. I am also much indebted to Mr. Clarence 

 Kennedy and Mr. Heilman C. Wadsworth for their valuable assistance 

 both in making the observations and in the tedious work of counting the 

 material.
