Ice Atlas 1985 - 1986. Monongahela River, Allegheny River, Ohio River, Illinois River and Kankakee River.
The ice maps in this atlas were prepared to document the 1985-86 ice conditions on those reaches of the Monongahela, Allegheny, Ohio, Illinois and Kankakee Rivers that are included in study areas for the River Ice Management (RIM) Program, namely river mile 0 to 12 on the Monongahela River, mile 0 t...
