Flood in Columbia County, New York

Heavy rain led to widespread flooding of small streams and creeks across the county, including Kinderhook Creek, and Claverack Creek, beginning Sunday evening on the 15th, and persisted through Tuesday evening on the 17th. This led to numerous road closures throughout the county, including New York State Route 66 between Bridge Street in Greenport, and the Fish and Game Road in Claverack. The most widespread flooding occurred mainly south of Route 23. In addition, numerous basements were reported retaining water near Stockport along Sotckport Creek.

Furthermore, a bridge at the intersection of County Road 16 and 23 collapsed in Hollowville due to high water along Claverack Creek around 2015 EST on the 15th.

The Town of Greenport wastewater treatment plant also sustained severe damage from the flooding of Claverack Creek.

Low pressure developed over the lower Mississippi Valley on Saturday April 14th, and then moved northeast while intensifying, reaching the southern Appalachians by Sunday morning, April 15th, and then just south of western Long Island by Monday morning, April 16th. This low became very intense, with a central barometric pressure falling below 970 millibars upon reaching just south of Long Island Monday morning. The low then headed off the New England coast by Tuesday morning.

This intense coastal storm spread heavy precipitation across the lower and mid Hudson Valley region of New York, starting on Sunday, and persisting into late Monday. Initially, the precipitation fell as a mixture of wet snow, sleet and rain, with snow and sleet more prevalent across the higher elevations. The precipitation changed to plain rain by late Sunday afternoon into Monday.

Liquid equivalent precipitation totals from this storm ranged from 3 to 8 inches. This led to widespread flooding across the lower and mid Hudson Valley region from late Sunday into Monday evening.
