LK Texana is a reservoir located in Jackson County, Texas. It was created in 1966 by the construction of a dam across the Navidad River. The reservoir has a capacity of 11,456 acre-feet and a surface area of 1,100 acres. The hydrology of LK Texana is influenced by the Navidad River, which is the primary inflow, and the Tres Palacios River, which is the primary outflow. The reservoir is used for both agricultural and recreational purposes, including fishing, boating, and camping. The surface flow of the reservoir is supported by local runoff and rainfall, and there are no significant snowpack providers in the area. The area surrounding LK Texana is primarily used for agriculture, including cattle grazing and crop production.
