high Muffs, ^Yhu■h. are from two hiimlred to three hundred feet above the 

 Avater level, but in places there are low points which extend out from the 

 bluffs into the lake for one-fourth of a mile or more, and on these niimerous 

 flshermeu are located. Seining, also other forms of netting, is allowed in 

 the lake, so an abundance of material for study can readily be obtaiued. 

 The water is usually clear and varies in depth from ten to thirty feet. 



As is well known. Lake Pepin is simply a remnant of what was once 

 the large glacial Mississippi Kiver. At the lower end of the lake the Chip- 

 pewa River empties from the Wisconsin side and carries with it a great 



amount of sediment, chiefly sand. This deposit has tilled up the bed of 

 the original stream at that point, and consequently dammed it and pro- 

 duced a lake. At all other places along its course what was once the 

 magnificent Mississippi, two to four miles in width, is now narrowed down 

 to one, or at most two or three, small channels and a few bayous. At the 

 upper end of the lake the delta is exceedingly well marked. There are 

 three main channels of the river, several lakes and numerous bayous, 

 some with water connection and others without, during the di-y season.
