Truscott Brine Lake is located at river mile 3.6 on Bluff Creek, a tributary of the North Fork of the Wichita River, approximately 3 miles northwest of Truscott, Texas. The embankment was completed in December 1982.

The salt source near Guthrie, Texas, on the South Fork of the Wichita River is pooled up using an inflatable dam at the Bateman Pump Station. From the Bateman Pump Station, the salt water is pumped through a 22-mile pipeline into the lake. Truscott Lake is totally contained with no means of discharging water. Approximately 4 million gallons of salt water per day is pumped into the lake.

The dam is an earth-filled embankment 15,500 feet long and rises to a maximum height of 107 feet above the streambed.  Truscott Brine Lake contains brine flows from collection facilities at Areas VIII and X.

The spillway is an excavated, uncontrolled, saddle type, 1,000 feet long.  Discharges of 13,200 cubic feet per second for the Standard Project Flood and 35,400 cubic feet per second for the Probable Maximum Flood could be passed by the spillway.

Estelline Springs Area V is located on the Prairie Dog Town Fork of the Red River in Hall County, about one half mile east of Estelline, Texas. The structure is an earthen ring dike, 9 feet high and 340 feet in diameter, constructed around the brine water Estelline Springs. The weight of the water contained by the dike stops the spring from flowing. The dike has stopped about 240 tons of chlorides from entering the Red River each day since it was constructed in 1964.
