A liquid has viscosity, a measure of its resistance to flow. The viscosity of water at room temperature is about 0.01 poises. A thick oil might have a viscosity of about 1.0 poise. As a liquid is cooled its viscosity normally increases, but viscosity also has a tendency to prevent crystallisation.
Toledo Bend Reservoir. Toledo Bend Reservoir is a reservoir on the Sabine River between Texas and Louisiana. The lake has an area of 185,000 acres (749 kmÂ²), the largest man-made body of water in (or partially in) Texas, the largest in the South, and the fifth largest (surface acre) in the United States.
Shreveport was established in 1837 in the southern part of the parish, and in 1838, the Louisiana portion of the Caddo cession, formerly a part of Natchitoches Parish, became Caddo Parish. Because the Indian agent had been so diligent in his duties, the migration of settlers to the southwestern United States beginning after the Louisiana Purchase in 1803 was precluded in the area.
