Christina River

The Christina River is a tributary of the Delaware River, approximately 35 miles (56 km) long, in northern Delaware in the United States, also flowing through small areas of southeastern Pennsylvania and northeastern Maryland. Near its mouth the river flows past downtown Wilmington, Delaware, forming the city's harbor for traffic on the Delaware River. The Port of Wilmington, opened in 1923 at the river's mouth, handles international cargo and trade.

The river rises in southeastern Pennsylvania, in Franklin Township in southern Chester County, and initially flows southeastwardly, passing through the northeastern extremity of Maryland in northeastern Cecil County, into New Castle County in Delaware, where it flows through western and southern areas of the city of Newark and then turns northeastwardly, passing the town of Newport and approaching Wilmington from the southwest. It receives White Clay Creek from the west near Newport, and Brandywine Creek in Wilmington, approximately 2 miles (3 km) upstream of its mouth.

Christina River (Alberta)

Christina River is a river in the Wood Buffalo region of northern Alberta, Canada. It is a tributary of the Clearwater River. Christina River is part of Christina Lake's 1,250-square-kilometre (480 sq mi) drainage basin. Christina Lake's waters flow into the Jackson River, which flows 11 kilometres (7 mi) before it empties into the Christina River. Christina Lake and Christina River are named to honour Christine Gordon, originally from Scotland, who was the first white women to live permanently in the Fort McMurray area, where she remained until she died in the 1940s.

Drainage basin

The source of the Christina River is Christina Lake (54°40'N 111°00'W), which is an elongated lake east of Conklin, between Lac La Biche and Fort McMurray, near Highway 881. The lake lies at an elevation of 556 m (1,824 ft) and has a total area of 21.3 km² (8.2 sq mi). It has a mean depth of 17.3 m (57 ft) and reaches a maximum depth of 32.9 m (108 ft).

Cenovus Energy operates a Steam Assisted Gravity Drainage (SAGD) project in the Christina Lake area, tapping bitumen from the McMurray Formation.
