Ice Observations on the Allegheny and Monongahela Rivers
Corps of Engineers and National Weather Service records if ice conditions on the Allegheny and Monongahela Rivers in Pennsylvania and West Virginia were analyzed for seven recent winters. The on-ground observations recorded daily at a number of lock and dam locations were issued in the form of alpha...
