Right now, the water is murky and the current is unbelievably fast.
While Thursday was sunny day, with more rain on the way, people who have been flooded before are nervous.
That's why Randy Bishop, owner of a Lambertville antique shop which sits right on the river, already started clearing out the basement as a precaution.
"If the storm comes on the back of the other one, you won't have a lot of time to react. So we're going to go ahead today, empty our basement, prepare things and stage things if we do have to get out quickly," said Bishop.
After being flooded three times in recent years the shopkeepers here want to be prepared.
"Understand it's going down a few feet, but it's going to pop up if we get heavy rains Friday and Saturday morning," said Dan Margo.
It's the same story at the art gallery next door, where they just finished renovations two weeks ago from the 2006 flood.
"We're packing tonight. I have a car and people who will help me move out," said Ildico Belenikin.
Up river in Riegelsville, the Delaware crested at over 20 feet around noontime. That's still a foot-and-a-half below flood stage here, but locals are keeping a close watch.
"Tires floating down (the river). You start seeing part of people's dock floating down. It's scary," said Kelly Harper.
Justine Ferrari is getting ready to open a market and catering business in town, but worries about filled reservoirs upstream.
"Now until Saturday. Somehow they are going to have to let water out. I'm afraid it is going to be worse than the last three floods," said Ferrari.
