C-MAP NA-C039 Ohio River Cairo To Pittsburgh

The C-MAP NA-C039 Ohio River Cairo To Pittsburgh chart card is an essential navigation tool for anyone operating a vessel on one of North America's most heavily trafficked inland waterways. This detailed electronic chart covers the critical middle section of the Ohio River, from Cairo, Illinois to Pittsburgh, Pennsylvania—a corridor that demands accurate depth readings, current information, and precise waypoint plotting. Whether you're a commercial barge operator, recreational cruiser, or fishing enthusiast navigating these waters, accurate navigation data directly impacts safety, fuel efficiency, and successful river operations.

C-MAP's cartography for this region includes high-resolution bathymetry, lock and dam locations, commercial channel markers, anchorage areas, and hazard zones that define navigation in the Cairo-to-Pittsburgh corridor. The chart integrates real-time water level data compatibility, allowing you to adjust shallow-water routes based on current conditions—critical when maneuvering through variable depths common in mid-river sections. The card format ensures compatibility with standard C-MAP plotter systems, delivering the precision you need without bulky paper chart storage or constant updating concerns. Digital formatting also enables rapid zooming between overview and detailed approaches to major locks, bridges, and port facilities.

This chart card works with any C-MAP-compatible marine GPS/chartplotter system installed on your vessel, making it an economical upgrade for existing electronics. Commercial operators, fishing guides, and serious cruisers benefit most from the detailed lock and dam data, current flow information, and emergency anchorage references that this section covers. The lightweight, durable card format stores easily aboard and eliminates the need for regular chart corrections that paper users face, ensuring your navigation data remains current throughout the season.
