As a result of heavy rains and snow falling on frozen ground, a flood occurred in the Esquatzel Coulee area on February 21-22, 1956, which, in Connell, was the greatest known since the town was settled in about 1888. Long-time residents of Connell report that the flood was much greater than the next highest ones, those of August 1907 and February 1949 Damage to municipal works, residential areas, and business property was estimated at more than a million dollars.Three other noteworthy floods occurred in 1956 that are included in this report but none was as destructive as the February flood.On January 4 a minor flood occurred that in general was confined to the main channel* The flood of May 8 was severe in two small areas, one near Lind and the other near Connell. Some farms and the town of Connell were damaged by flood water. On July 2 an intense rain just east of Connell resulted in a small lake forming downtown but damage was considered negligible.
