NOTES UPON FLOODS IN LAKE GEORGE. 247 
In the —— abstract of the history of lake levels I have 
endeavoured to ¢ - —_— as concisely as ible. It will be 
n in the dings m wn from these that the rise in 1816 is 
shaded, this was done rs a iaationte that itis assumed from the floods 
many cases, for instance, in 1832 Su urveyor Hoddle See 
some land at the south end of the lake, and in his plan shows the 
then water-line very clearly. Three years later, that is in 1835, 
he went there again, and in his plan shows the lake margi 6 
chains within the previous one. Now where the inclination is 
10-28 in 60 chains, it is 1 foot in 6 chains, and therefore 1835 
was 1 foot lower than 1832. 
1816.—Very heavy floods occurred in the Hawkesbury in 1816 
after : drought of three years’ continuance. It was very wet 
, and a still higher flood swept the Hawkesbury in 
March this year. In 1818 it was rather dry, but 1819 brought 
two great floods in February. There were more floods in 
March again in June, 1820, one of the greatest floods ever 
n the Hu nter this year. 
1818. me ‘1818, the blacks told Dr. Thr osby’s exploring party 
when near Lake George that there was a great body of water 
in it. 
1820. Ai hes seen by the Governor in October, 1820, Lake 
George was a splendid sheet of water. 
1821.—Mr. J. R. Styles saw the lake from Governor’s Hill, it was 
a magnificent sheet of water reaching nearly to the town of 
Collector. 
1823.—From what the blacks told him, Mr. H. Hall thought Lake 
rge was at its highest flood in J une, 1823. 
1824. — Messrs ‘Ho ee oe Hume’s Overland Journal estimates the 
lake as 20 miles 
1824. i H. Hall (Olieeate) there were some dead trees in the 
margin of the lake this year that had not then lost their 
bark, while there were other trees farther into the lake that 
looked as if they had been dead for years ; level of water 
probably about same as 1823. As the water in 1874 
certainly went as high up as any of the dead trees, and 
actually killed a few more, it would seem to be more than 
likely that the water was as high in 1823 as in 1874. 
1825. —There was no rise this yearin Lake Bathurst, probably 
1828. "The lake was ete in August, 1828, by Mr. Dixson, 
Government —— and found to be 15 miles long, which 
is its actual length. b; y railway marked trees now, January,
