March 15th through the 21st is the National Weather Service’s “Flood Safety Awareness Week”!
Visit the NWS’s Flood Safety page for some information and tips on how to prepare for, deal with, and recover after a flood – and safety measures to take when flooding does occur.
On Thursday, March 5th, the National Weather Service released a Winter/Spring Flood Potential Outlook for Eastern NY and Western New England:
WINTER/SPRING FLOOD POTENTIAL OUTLOOK NATIONAL WEATHER SERVICE ALBANY NY 1157 AM EST THU MAR 5 2015 ...Winter Spring Flood Potential Outlook 5 for Eastern New York and Western New England... This is the fifth of a series of Hydrologic Outlooks issued by the National Weather Service every two weeks...which refers to the potential for flooding across eastern New York State...southern Vermont...Berkshire County Massachusetts...and Litchfield County Connecticut. The major river basins in this area are the Hudson...the Mohawk...and the Housatonic. This outlook is valid for the two-week period March 5 to March 19. ...Overview... The potential for snowmelt flooding for the winter and spring of 2015 is generally near normal...since snowpack is now near to above normal. The potential for ice jam flooding is near normal for the next two weeks. ...Observed Snow Depths and Water Equivalents... Snow depths between one and a half and two feet were the norm across elevated terrain in the southern two thirds of the outlook area...including the Catskills...the Berkshires...and the Litchfield Hills. These locations are carrying between three and seven...locally eight...inches of liquid equivalent. Elsewhere...snow totals in the Adirondacks and southern Green Mountains measured between a foot and a half and three feet...containing 2 to 8 inches of snow water equivalent. These totals bring us into normal to slightly above normal ranges for this time of year. ...River Flows and Ice Conditions... Flows in area rivers are below normal with minimal runoff due to below normal temperatures. Most rivers and streams are ice affected. River ice cover and thickness is above normal and with cold temperatures remaining in place for at least the first week of the outlook period...river ice will remain in place for at least the next week or so. ...Soil Moisture Conditions and Water Supply... Soil moisture continues to decline in the outlook area with the ground frozen and no runoff ongoing. Precipitation totals for the last 30 days are near normal up to an inch and a half below normal. New York City water supply reservoirs are at about 74 percent of capacity as of March 4th. This is about 13 percent below normal for this time of year. Hudson River-Black River Regulating District reservoirs range from about 2 feet above target at Great Sacandaga Lake to over 5 feet below target at Stillwater Reservoir. ...Temperature and Precipitation Outlook... The forecast for the next week calls for below normal temperatures and precipitation. However..the official National Weather Service 8-14 day outlook for March 12th through the 18th calls for near normal temperatures and near to slightly below normal precipitation. This indicates a warmup from previous outlooks which featured below to well below normal temperatures. ...Summary... While the potential for snowmelt flooding is near normal for this time of year...the overall weather pattern favors colder than normal temperatures for about the first week of the outlook period. Thus it is unlikely that we will have enough runoff to cause any significant rises on area rivers and streams within the first week or so of the outlook period. However...a return to near normal temperatures appears likely by midweek next week...with highs in the upper 30s to upper 40s. Ice coverage is near 100 percent but with cold temperatures in the forecast for the next week...no immediate threat for ice jams exists. However...river ice remains in place and is setting the stage for potential ice jam issues when temperatures begin to rise. Any rapid runoff events and dramatic increases in flow would have the potential to produce ice jam problems...but most likely not in the first half of the two week outlook period. Again...the second week of the outlook period could see warmer temperatures but not necessarily enough to cause rapid ice breakup so monitor forecasts at weather.gov/albany for the most up to date information. The sixth Winter Spring Flood Outlook is scheduled for Thursday... March 19. Extended hydrologic information will be included in the Hazardous Weather Outlook when necessary. It is important to remember that heavy rainfall can produce flooding at any time of year even in areas that have a below normal potential for flooding. Observed and forecast river information can be found on our web page at www.weather.gov/albany.
Gretchen Gary and Shorna Allred, part of the Hudson Estuary Watershed Resiliency Project at Cornell University’s Human Dimensions Research Unit (HDRU), have just released their final Needs Assessment on riparian landowners’ risk perception, attitudes, and behavior with regard to flooding and stream management. The results will be used to inform education and outreach to private landowners in the Hudson River Estuary.
The specific objectives of the Needs Assessment were to:

When thinking of countries that have had to deal with flood control and water management at an extensive level, one’s mind may instantly go to the Netherlands. Today, approximately 27 percent of the country is actually below sea level. This area is home to over 60 percent of the country’s population of 15.8 million people. Dealing with floods is second nature to the Dutch, who have gone to great measures to manage the impressive force of the North Sea and the country’s rivers, including the famous Rhine, which flows into the Atlantic Ocean at the critical port city of Rotterdam.
David Berg, AICP, LEED AP and Cameron Engineering & Associates, LLP gave a presentation for New York State’s Climate Smart Communities Program on many of the management techniques the Dutch have already implemented (or plan to implement) as this low-elevation nation continues to thrive in the face of the rising threat of global climate change and sea level rise.
Here are the slides from their presentation (two parts):
On Tuesday, October 2nd, the Resiliency Project hosted a seminar at its Dutchess County location entitled “Streams 101: Planning for Streamside Habitats and Flood Resilience”. This educational presentation provided basic information on stream dynamics – how streams naturally flow on the land, how streams respond to disturbance and problems that can arise from the interaction of streams and human-built infrastructure, especially during flood events. Presenters also touched on municipal case studies and useful planning tools and resources to assist municipalities in adapting and becoming more resilient to future flood events.
