The following comes from the journal of Daniel Harmon, a fur trader who worked for the North West Company in the western interior of Canada. While he was at Swan River Fort, spring runoff was unusually high:
April 19, 1801. Sunday. On Friday last there fell nearly a foot of Snow, which however soon dissolved and caused the River to overflow its Bank to such a distance as to oblige our People who were making Sugar to leave the Woods and come to the Fort.
May 10, Sunday. It has for three successive Days Rained constantly, which caused the water in the River to rise since yesterday four feet. Yesterday one of our Men went a shooting Ducks, but lost his way and therefore was under the necessity of passing the night in the wood, with nothing to cover himself from the cold & Rain that poured down in torrents…
May 13, Wednesday. The late Rains we have had has caused this River to overflow its banks to such an uncommon distance, that this morning when I arose I was not a little surprised to find Seven Inches of water on the first floor, which is what the oldest person here does not remember to have seen before, and we are obliged to leave our Fort and Pitch our Tents on a small rise of Ground no great distance off, and where we shall remain till the deluge is past.
May 20, Wednesday. The water has left the Fort and we with pleasure quite our Tents to occupy our former Dwellings.
