The Delaware River and its tribs rose quickly after that 70 degree day and it was all snow and ice melt. The river at Riegelsville is running around 6' which is almost double the flow of the previous week, but still a moderate level for this time of year.
That's a great sign for all those who dwell by the river. There's still lots of thick ice in the lakes, and clogging the big eddies of the Upper Delaware River, but it looks like the trend towards gradual thawing and melting will continue.
