Flood Details - 1920-04-06 - 1920-04-10

Saint John River Basin: At Hartland, the rain was reported to have begun during the evening of April 5, and continued throughout the night. The river was said to have risen rapidly and by 9:30 a.m. on April 6, the ice began to move and jammed a short distance below the town. The rapid rise in water levels resulted in several families being forced from their homes, the evacuation of livestock and damaged stock in the basements of some stores. These flood conditions were reported to have lasted a very short period of time as the jam broke under its own pressure. The ice run pounded the piers of the new bridge for a three hour period, destroying the two western-most spans. As a result of the bridge loss, a steam ferry was put into operation at Simonds. It was anticipated that temporary spans would be installed and traffic would resume on the structure by May 15. Another ice jam was reported to have formed at the Hawkshaw Bridge. The debris from the Hartland Bridge was also reported to be piled up on this jam. Lower Saint John River Basin: In the Keswick Islands area, below Crock's Point, the inundation of the C. N. railway line was reported due to a large ice jam. One washout was also reported in this area. The ice was reported to have carried away the rigging of the wire ferry and several barns and buildings on the islands. The Fredericton bridge was also considered to be in imminent danger from the moving ice. An ice jam in the Nashwaak River at Durham Bridge caused the inundation of the Canada Eastern Railway line. This resulted in a disruption of service between Fredericton and McGivney. St. Croix River Basin: In the St. Croix River Basin, the bridge at St. Stephen (International Bridge) was reported to be affected by the floodwaters. At Milltown, the MacAllister Bros. Grist Mill was described as being surrounded by water. The Cotton Mill was forced to close on April 6 and remained closed for about three weeks due to the high water. Magaguadavic River Basin: At St. George, the Magaguadavic River reached its highest peak in several years. At Second Falls, a portion of the dam was carried away. Roads in the area were covered with up to five feet of water in places. Petitcodiac River Basin: In the Moncton area, the Humphrey's Dam broke, flooding areas downstream. Other dams in the area were said "to be in danger".

Rain, melting snow and some ice jams.

Saint John River Basin: The ice in the Saint John River at Hartland was reported to be in the order of two feet thick. Local residents stated that "a greater depth of snow than had been known for years" was on the ground prior to the thaw. The ice run was said "to be the heaviest ever witnessed at Hartland". When the ice jammed downstream of the town, water levels were stated "to have risen six feet in less than 10 minutes". The ice run which followed was reported to be moving at 15 miles [24 km] per hour. Water levels at Crock's Point were reported to be 11 feet above summer levels.

No estimates of the flood damage were presented.
