NOTES UPON FLOODS IN LAKE GEORGE. 955 
3 feet 6 inches below 1874 mark ; so that from January, 
1870, to end of the winter in 1874, the lake must have 
risen 17 feet 6 inches. 
. On the same date (30th June, 1877,) I sounded all over 
Cooper’s Bay and along Cooper's shore, and could find 
no greater depth than 21 feet. his proves that 
previous to 1870 the depth generally over that part of 
the lake could have been ; 
“The (see Mr. Kenny’s letter) lake may be deep further south 
along the Currendooley san but from what I can learn I don’t 
think there is much differe 
“T am inclined to think “that most of what has been said about 
the lake in past years has been simply guesswork and tradition. 
These are facts verified by actual measurement.” 
Mr. A. Chisholm, of Winderradeen, under date 19th June, 
1878, says: “Surveyors are at present engaged in making a trial 
survey fora railway line to Maneroo. Mr. Mountain, the one 
who has charge of the portion from Bredalbane to Bungendore, 
has got as far as Lake George, and he tells me that the present 
level. of the water is, or was on 10th June, 2,225 feet above the 
sea. This he has ascertained by actual levelling from Bredalbane 
platform. On the same date the lake had fallen 5 feet 6 inches 
below the highest mark of 1874. 
re Kenny, of Kenny’s Point, cen under date, 3rd 
August, 1876: “Any information I can give about the lake, I 
fear will not be very valuable for eibrolaptast purposes, but such 
as it is I have much pleasure in placing it at your service. The 
present dimensions of the lake may be fairly estimated as 
follows :—Length 20 miles, average breadth 7 miles, average depth 
20 feet (deepest part would be then 22 feet, see diagram 1 
therefore Mr. Kenny’s average of depts is 2 feet less than deepest. 
I state this for comparison). In 1826-7 the length and breadth 
covered with water, at which stage it arrived in 1837. With 
slight fluctuations it are eamne in this — until 1840-41, when it 
the depth very svifling. There was little increase in this until 
1852, during the winter and 8 of which year the lake became 
filled to fully seven-eighths of its present area, but the depth did 
not — an average of 9 feet (11 feet in deepest) ; 3 since then it
