Llano Grande

Llano Grande Lake, two miles south of Weslaco in southeast Hidalgo County (at 26?07' N, 97?58' W), is part of the Rio Grande delta drainage system and lies within the Llano Grande Grant, which was conveyed by the Spanish government to Juan Jos? Hinojosa, chief justice of Reynosa, Tamaulipas, in 1778. The lake, which is six miles long and 600 feet wide at its widest place, is supplied by Oso, Enguerrado, and Badena resacas, all of which enter from the west. Separate outflows from the eastern end of the lake form Arroyo Colorado and Lake Tampacuas, which flow into the Laguna Madre and the Gulf of Mexico.
