It's not there anymore, but for a while in the early-2010's the sat pix for central Mass showed a lot of river flooding upstream of the Birch Hill Dam on Millers River, flooding a lot of Lake Dennison State Park. The dam is for flood control for all the large rivers draining into the Connecticut River, and the flooded area existed for that purpose (so not quite the disaster you're seeking). Since it was early 2010's and no greenup of the foliage, I presume it was from March 2010 when the area had over 10 inches of rain and melted precip in about a 3 week period.
Historic aerials has a 2010 pic but it's clearly summertime based on the greenup in the area, and the river is back to its normal state at that point.
