A spring freshet? The river shot up between six and seven feet depending on the gage in little over one day. A rain storm and break-up of ice with some snow melt put it up and it's coming back down again, gradually.
The water just has that late winter thaw look to it.
Meanwhile the smaller creeks and rivers below the Water Gap are low for this time of year. The Musconetcong River is only 180 CFS and the Tohickon Creek is around 123 CFS. The later will be ripping at around 300 CFS with the whitewater release scheduled for March 21 & 22.
