[Extract]
Dear Sir We are informed by Mr [James] Price that there is not water enough in Lake St Pierre for a frigate to pass over with her Gunns & Stores: he says that there is not, even at this season of the Year when the water is highest, more than between 14 & 15 feet in the channel, which is very narrow. If this representation be just, our Gondaloe now at the Mouth of the Sorrell may perhaps prevent the enemies ships of War from coming higher up the River St Lawrence than Lake St Pierre....
La Prairie May 12th 1776
6 oClock P.M.
P S the Depth of water in Lake St Pierre may be ascertained by Sounding.
