I think it's safe to say that at this point, *most* streams are at least 50% iced over, if not completely iced over. Limestoners are the only bet right now and even the Donegal had some ice on it the other day.
I did a long looping drive through southern Lancaster County and down across the Conowingo Dam and up through York County and pretty much every stream we crossed was frozen over with just small patches of open water. Spring can't get here fast enough.
I am going to surprise some of you, I was in Leetonia on Monday and Cedar Run is iced over, I know that is hard to believe. As are all other streams I have been near in Tioga county. hopefully, no one is surprised by this.
Of the streams I cross over each day, the mouth of Donegal is frozen over, but it flows into a dammed up section of the Chiques (which is frozen over, except below the little dam), so that is not surprising. Swatara is frozen over, Suskie is frozen over, but the stream that carries the effluent from a sewer plant is flowing strong!
