The two channels merge into one and form an area of water from 30 feet to 66 

 feet in depth, one mile in length and with a maximum width of three-quarter* of 

 a mile. This area of deep water lies nearer the south shore, its center being one- 

 third the distance from the south shore to the north shore. Near Black Stump 

 Point the deep water narrows abruptly from the north, and 500 feet out from 

 Black Stump Point its width is but 200 feet. West of Black Stump Point the 

 ■deep water widens abruptly to the north to a width of one-quarter of a mile and 

 deepens to 63 feet 3 inches. West of this the area of deep water narrows again 

 and the water having a depth of 30 feet ends one-quarter of a mile southeast of 

 the entrance to the channel between the main lake and Syracuse Lake. 



Between th^ deep channels from Crow's Bay and Jarrett's Bay the area having 

 a depth less than 30 feet is one and one-quarter miles long, 1,300 feet wide, and 

 contains an area one mile long and 500 feet wide over which the water is less 

 than 10 feet deep. 



If the level of the lake were lowered 30 feet there would remain four bodies 

 ■of water connected by channels from 100 feet to 200 feet wide and less than 10 feet 

 ■deep. These four bodies of water would be: (1 ) a small area in Crow's Bay with 

 a maximum depth of 19 feet; (2) about one-half of Jarrett's Bay with a maxi- 

 mum depth of 38 feet; (3) the main body of the lake, its width decreased almost 

 -one-half, and its maximum depth being 36 feet; (4) a small area northwest of 

 Black Stump Point with a maximum dejith of 33 feet. Lower the level of the 

 lake 10 feet more, that is, 40 feet below its present level and these four bodies of 

 •water would remain as separate lakes, the connecting channels now being dry. 



Great changes in the shore line will take place if the level of the lake be 

 lowered to a much less extent. By observing the map it will be seen that a low- 

 ■ering of the level of the lake to the amount of 10 feet would move the shore line 

 to the first contour line. This would leave one-half the bottom of Johnson's Bay 

 •dry land ; it would move the shore line along Crow's and Jarrett's Bays from 400 

 feet to 1,000 feet into the lake. Clark's Point would extend 2,000 feet further 

 north, and the distance between Clark's Point and Ogden Point would be reduced 

 from 4,000 feet to 1,800 feet. The south shore line from Clark's to Conkling Bay 

 would l)e moved northward distances varying from 250 feet at Iron Spring Point 

 to 1,000 feet along the shore west of Black Stump Point. The north shore line 

 from Ogden Point to the Channel would be moved southward from 900 feet to 

 2,000 feet, and at one place — between Jones' I<anding and Black Stump Point — 

 4,000 feet, i-educing the width of the lake at this place from 1 mile to 500 feet. 

 The Channel between the main lake and Syracuse Lake would be drained, and 

 the greater part of Syracuse Lake would become dry land.
