Oh Baby it's cold outside! Temperatures have been below freezing for most of the past two months. We can see the impact of these cold winter temperatures on our river's water level. Average water depths have dropped by roughly 1/2 foot since early November. This drop is caused by river and coastal waters contracting in the cold. A contraction of even 0.2% in a large body of water such as the Mid Atlantic Bight can cause a significant drop in water level. For a more detailed description, see this story describing the winter water level drop.
