Above normal to record precipitation of 5 to 9 inches occurred in April across a large area of New York State. There was above normal snowpack across the higher elevations of the Adirondacks with snow depths at least a foot above normal. A warm front lifted northward across the area on Tuesday, April 26th, ushering in a warm and humid airmass. Temperatures rose into the 70s and 80s across the area on Tuesday and again on Wednesday, April 27th (15 to 25 degrees above normal). In addition, overnight lows were mild.
An area of heavy showers and embedded thunderstorms accompanied the warm front as it moved through on Tuesday, April 26th, impacting areas mainly north and west of the Capital District. The boundary became stationary near the Saint Lawrence River Valley and northern New England. A disturbance in the upper levels of the atmosphere and an area of low pressure moving towards the Great Lakes Region focused another round of showers and thunderstorms that impacted the western and central Mohawk Valley, Adirondack region, and the Upper Hudson River Valley including the Lake George Region late Wednesday afternoon into the early evening, April 27th. Yet another wave of low pressure moved into the eastern Great Lakes Region Thursday morning, April 28th. This low intensified as it approached and had strong upper level support favorable for strong to severe thunderstorms. Thunderstorms producing severe weather and very heavy rainfall moved over already saturated ground to the north and west of the Capital District during the morning hours.
The combination of several rounds of heavy rainfall from convection, rapid snowmelt due to the warm temperatures and above normal soil moisture led to increased runoff and rapid river rises. Widespread flooding of rivers, streams and creeks occurred resulting in road closures and flooding of properties. On Thursday, April 28th, an earthen dam failed sending water, dirt and debris from Lewiston Pond on Route 9 at Brower Road into the Longberry Lake which is Saratoga Springs' drinking water supply (no health threat report). Many record crests occurred on rivers, creeks and streams throughout the upper Hudson and upper Mohawk basins.
The following river points reached record levels:
Hudson River at North Creek in Warren County, Fort Edwards in Washington/Saratoga counties and Schuylerville in Saratoga/Washington counties.
Stillwater Reservior at Beaver River in Herkmier County.
Great Sacandaga River at Conklingville and Stewarts Bridge near Hadley in Saratoga County.
West Canada Creek near Wilmurt and Kast Bridge in Herkimer County.
Indian River near Indian Lake in Hamilton County.
Hinkley Reservior at Hinkley in Herkimer County.
As a result of the flooding, states of emergency were declared in Indian Lake and Long Lake Hamilton County, Town of Johnsburg Warren/Hamilton Counties, Town of Chester Warren County, and in the Village of Middleville Herkimer County.
The following school districts were closed on April 29th due to the flooding: Indian Lake and Long Lake in Hamilton County and Johnsburg in Warren County.
