USA – December 12th, 2012

Several fires can be seen in southeastern Oklahoma and southwestern Arkansas, around the Ouachita Mountains. The range itself runs through west central Arkansas and southeastern Oklahoma, although its subterranean roots may extend as far as central Texas (in the full image, the city of Dallas can be seen to the southwest). The Ouachita Mountains form the U.S. Interior Highlands, one of the few major mountainous regions between the Rocky Mountains and the Appalachian Mountains.

This image stretches from Texas, USA, across Mexico. The relatively flat terrain in Texas in the upper right quadrant contrasts with the Sierra Madre mountain ranges running parallel to both coasts of Mexico. Visible on the plains in the upper right corner is the city of Dallas, appearing as a large grey area. Another large city visible in this image is Guadalajara, located in Mexico near Lake Chapala at the bottom center.

The cities of Dallas and Fort Worth appear surrounded by lakes in this radar image of Texas, USA. Dallas has a total area of 385 square miles (997.1 km2), 342.5 square miles (887.1 km2) of it being land and 42.5 square miles (110.1 km2) of it (11.03%) water.

The Dallas area is mostly flat with marked terrain differences only found near waterways. Dallas was founded along the Trinity River, which is flanked on both sides by 50 feet (15 m) tall earthen levees to protect the city from frequent floods.

Also situated on the Trinity River is Lewisville Lake (center right), on the Elm Fork of the river in Denton County near Lewisville. The lake is primarily used recreationally for boating and watercraft, however, it was built for flood control purposes and to serve as a water source for Dallas and its suburbs.

Lakes in midwestern USA - March 1st, 2009

The city of Dallas and its suburbs, in the state of Texas, USA, is visible as a grey and tan area towards the center left. It is surrounded by many lakes and reservoirs.

The most evident include Lewisville Lake, just northwest of Dallas. It is a man-made freshwater lake located on the Elm Fork of the Trinity River near Lewisville.

The lake is primarily used recreationally for boating and watercraft, however, it was built for flood control purposes and to serve as a water source for Dallas and its suburbs.

Just north of Lewisville Lake is Lake Ray Roberts, a 29,350-acre (119 km2) lake located 10 miles (20 km) north of Denton, Texas. It supplies water to Cooke, Grayson and Denton counties.

Even further north, above Lake Ray Roberts, is the sizeable Lake Texoma, one of the largest reservoirs in the United States. Its surface spreads over 89,000 acres (360 km²) at the confluence of the Red River and Washita Rivers.

It is formed by Denison Dam on the Red River in Bryan County, Oklahoma, and Grayson County, Texas, about 726 miles (1,168 km) upstream from the mouth of the river. The dam and reservoir were created for flood control and generation of hydroelectric power.

Northeast of Dallas are Lake Lavon (above) and Lake Ray Hubbard (below). Both are artificial freshwater lakes located on the East Fork of the Trinity River. Like many of the others in the region, Lake Lavon was designed for flood control, conservation storage, and recreational use.

Lake Ray Hubbard, formerly Forney Lake, on the other hand, was designed to provide water to the North Texas region. It is  impounded by the Rockwall-Forney Dam and measures 22,745 acres (92 km²) in size, with a storage capacity of 490,000 acre-feet (604,000,000 m³) and a maximum depth of 40 feet (12 m). Several areas of the lake have been infested with hydrilla, which contributes to its green color.

East of Lakes Lavon and Ray Hubbard, approximately 53 miles (85 km) east of Dallas, lies Lake Tawakoni. It is an artificial reservoir used for water supply and recreation. It covers 36,700 acres (149 km²) and has a mean storage capacity of 926,000 acre feet (1.14 km³).
