FLETCHER LAKE, INDIANA, AND ITS FLORA AND 



FAUNA.*

Fletcher Lake is situated in the southwest corner of Fulton 

 County, Indiana, about 12 miles nearly due north from Logans- 

 port, and only a few rods north of the Cass County line. It is 

 about 3 miles northeast of Lucerne on the Terre Haute and 

 Logansport Railway. Its position is about 40° 55' 80" north 

 latitude and 86° IS' IG" west longitude. It is among the 

 southernmost glacial lakes of Indiana. 



Tlie writers visited Fletcher Lake, October 6, 1000, in the 

 interest of the U. B. Bureau of Fisheries, for the purpose of 

 making a physical and biological survey of it. Many soundings 

 were taken and the depths of the lake in many places accurately 

 determined. Many tempci-ature ol).servations were made and 

 recorded, the character of the bottom and shores studied, and 

 collections made of the animal and plant life of the lake. In 

 these investigations valuable assistance was rendered by Messrs. 

 John J. Hildebrandt and A. P. Jenks of Logansport. 



Fletcher Lake is an elongate body of water with parallel sides 

 and no bays, capes or marked irregularities of shore line. Its 

 length is about | of a mile and its width i, the area being about 

 30 acres. It appears to occupy a sort of closed-up, narrow 

 valley. The long axis lies nearly due east and west. The 

 abruptness of the descent all around the lake is worthy of note, 

 as in this respect it differs markedly from Lake Maxinkuckee, 

 and chjsely resembles such lakes as Holem, Cook and Meyers t 

 of the Twin Lakes group in Marshall County, Indiana.
