Trinity River, Texas courtesy of Wikipedia

The Trinity River rises a few miles from the Red River in far northern Texas in three principal branches:  East Fork, Elm Fork and West Fork. The river runs 710 miles down to Lake Livingston making it the longest river contained within a single state.  Those waters than drain into Trinity Bay, an arm of Galveston Bay, that is an inlet of the Gulf of Mexico.  The Trinity is a wonderful natural resource for the City of Dallas converging into a single stream at the  Elm Fork area.

The Trinity has been identified as the stream that the Caddo Indians called Arkikosa in Central Texas and Daycoa nearer the coast, as well as the one that Réne Robert Cavelier, Sieur de La Salle, in 1687 called River of the Canoes. The name Trinity (La Santisima Trinidad) is supposed to have first been applied to the present stream by Alonso De León in 1690. Domingo Terán de los Rios in 1691 called the same stream Encarnación de Verbo. Domingo Ramón in 1716 probably applied the name Trinity to the present Brazos, for, when he later reached the Trinity, he was told by the Indians that other Spaniards called the stream the Trinity. The Marqués de Aguayo and other later explorers used the name Trinity consistently.


During the colonial period of Texas history, the land along the lower course of the Trinity was settled as far up as Anderson County. The Anahuac disturbances were among the most historically significant events of the era. Settlement up the Trinity valley continued to advance rapidly in the period of the republic. Beginning about 1836 numerous packet boats steamed up the Trinity River, bringing groceries and dry goods and carrying down cotton, sugar, cowhides, and deer skins. Today, once the waters of the Trinity River leave Dallas city limits, over 50% of the cities, ranch and agriculture areas get their water from the river.
