Why did the Susquehanna River rise overnight?

UNDATED — The Susquehanna River rose overnight and prompted some concerns that there may be an issue at the fabridam.  However, according to officials at ShikellamyState Park and the MiddleAtlanticRiverForecastCenter, there are no changes to the bags in the dam and there have been significant rains to our north.

If you live on the main stem of the Susquehanna River, you may have noticed that the water level went up about 2′ between Thursday and Friday from 7.5′ to 9.5′.  The river at Sunbury is now going down.  The river at Danville also rose sharply, From 3.5′ to 6.5′.  Bloomsburg went up 3.5′.

 

According to the Middle Atlantic River Forecast Center, rain in New York made for higher river levels and in Wilkes-Barre, the river rose 4′, but is now falling.

 

Jim Charles, co-owner of Isle of Que River Guides in Selinsgrove, said he woke up to a river level that was 18 inches higher than Thursday night, and it came within an inch of washing all of the business’ kayaks downstream.  He was concerned and said it “harkens back to the days when the dam was new, and failures were common.”

 

A rise like this, without rain in the immediate area, is typically the product of heavy rains up north or a dam release. (Sara Bartlett)
