Upstate New York and adjacent Western New England received an enormous amount of rain over the course of Tropical Storm Irene's brief visit. Major flooding of small streams and rivers occurred during and in the immediate aftermath of yesterday's storm.
Today, the major rivers, the Mohawk and Hudson, are cresting significantly above flood stage. My own home is in a voluntary evacuation area but far enough above the river so that I needn't worry. Some of my neighbors across the Hudson River in Waterford, however are not so lucky.
Here is a photo of the Waterford Harbor Visitor's Center parking lot from this morning, followed by a riverside view of the same location.
Here is the same scene in more normal times.
Here is another comparison, first from August, 2009 with the canal boat Day Peckinpaugh in the foreground and then from this morning.
And finally, a shot of the Mohawk River overrunning Delaware Avenue on Van Schaick Island in Cohoes, just a short walk from the scenes you see above. The shot is taken from North to South with the Mohawk River to the Right. The location of the cascade is just North of the open area between the rivers you can see on the Google Earth capture which shows the Mohawk River on the Left.
