NOTES ON DEPTH AND TEMPERATURE OF GREEN 



LAKE. 



By C. DWIGHT MARSH. 



Green Lake is situated in Green Lake county, and is something over 

 seven miles in length, and rather less than two miles in its greatest 

 breadth. It extends in a northeast and southwest direction, and is con- 

 sidered by geologists, to be of glacial origin, its shores at the western 

 extremity being formed of drift hills. 



The lake is of especial interest because of its depth, it being, I think, 

 the deepest lake within the limits of the state. 



While at various times soundings have been made by which the deep- 

 est parts of the lake were located with a fair amount of accuracy, the 

 only attempt at systematic soundings was made some years ago by 

 Prof. C. A. Kenaston, when he was connected with Ripon college. 

 Through the kindness of Mr. Henry Wolcott, of Ripon, I was enabled 

 to get the results of Prof. Kenaston's work. The soundings were made 

 in winter through the ice and the distances between stations chained off. 



Four lines of soundings were made: from Bowen's cottage to Oak- 

 wood Hotel, from Sandstone Bluff to Oakwood, from Sandstone Bluff 

 to Sherwood Forest, and from Sandstone Bluff to Sugar Loaf. The 

 following tables give the results: 



From Bowen's Point to Oakwood.
