What the reports say
Written by National Weather Service staff at the time of the event · public domain
The Hadlock Pond was breached washing out roads and destroying homes below the dam. It has been estimated that there was $5,000,000 of damage. This flash flood occurred under a clear sky and was not related to the weather, but was due to insidious disintegration of the dam structure over an extended period of time.
From January 8 through January 10, mild weather along with significant rain and snowmelt resulted in small stream flooding across Washington County. The Mettawee River at Granville, had what is believed to be the worst flooding ever known there. During the afternoon of January 8, the river crested at 10.68 feet which was more than three feet over flood stage. There was considerable flooding of fields along the Mettawee River. Approximately twenty road closures occurred throughout the county due to flooding and washouts with the most numerous closures between Greenwich and Whitehall.
Numerous roads were closed in and around Easton due to flash flooding from very heavy rainfall. The Cheese Factory Road was closed with a 7 foot deep trough through the road. Other roads closed to due flash flooding included County Route 113, Old Schuylerville Road and Meeting House Road.
