" 1800. Very high • old roads flooded. 



"1801. Still high.

" 1806. Very low ; reported by old settlers as lower than 1801 

 - — 2, and declining regularly to 1809 — 10 when it reached a

From 1815 to 1833, both inclusive, occasional measurement 

 to fixed data exist; the supplementary notes are here given. 



"1815. Rise of 3 feet above average level of 1814. (This 

 statement is not confirmed by an actual measurement made in 

 August, and is probably exaggerated).

 till 1819.

 Erie.

 — Col. Whiting. (Probably an error as this would place the 

 water unprecedentedly low. Col. Whiting probably ascertained 

 that the lake was falling and erred in taking some former high- 

 water mark for that of the preceding year).
