The Agua Dulce or Agua Fresca (Freshwater) were a Timucua people of northeastern Florida. They lived in the St. Johns River watershed north of Lake George, and spoke a dialect of the Timucua language also known as Agua Dulce. In the 1560s, Agua Dulce villages were organized into the chiefdom of Utina, one of the region's most powerful and prominent forces in the early days of European colonization in Florida. Utina had dealings with the French colony of Fort Caroline, and later allied with the Spanish of St. Augustine, who established several missions in its territory. However, the chiefdom declined significantly in the last decades of the 16th century, and the confederacy fragmented into at least three chiefdoms. The main body of the tribe withdrew south along the St. Johns River, and were known as the Agua Dulce to the Spanish. This chiefdom was largely abandoned by 1680. Additionally, a group of Christianized Agua Dulce migrated east towards St. Augustine, and became known as the Tocoy, but this small chiefdom disappeared by 1616. The Acuera, who spoke a different dialect but appear to have been part of the Utina confederacy in the days of French settlement, also broke away and established their own chiefdom. The Acuera proved more sustainable than the Agua Dulce and Tocoy chiefdoms, but had collapsed by 1680. Name Agua Dulce or Agua Fresca (both meaning "Freshwater") was a Spanish term for Timucua living along the freshwater lower St. Johns River, as opposed to the Mocama or "Salt Water" who lived along the coast. The Utina chiefdom of the late 16th century is so called after its paramount chief at the time of contact with the Europeans, Olata Ouae Utina; other spellings of the name include "Outina". The name "Utina" does not appear to be a designation specific to this group; uti-na means "my land" in Timucuan. The Saturiwa, another Timucua chiefdom who were enemies of the Utina, called them "Thimogona" or "Tymangoua", which is possibly the origin of the name "Timucua". The French followed the Saturiwa in this use, but later, the Spanish used the word "Timucua" for a much wider area of northern Florida, which they incorporated into their mission system as the Timucua Province. In the 17th century the Spanish thus came to know the principal tribe in the Timucua Province, who lived to the north of the former Utina chiefdom, as the Timucua.
