The Texas Forest Service reported in 1974 that Louisiana-Pacific had acquired the Altamil, Inc., sawmill at Trinity. The company, with twenty-five employees, had been producing about nine million square feet annually. In 1974, Louisiana-Pacific's Trinity operation was briefly mentioned in The Gulf Coast Lumberman's article of the exchange between Louisiana-Pacific and Champion International, the Corrigan operation for several of Champions, located in Montana, Wyoming, and California. The 1975 edition of Directory of the Forest Products Industry noted that twenty-five employees had produced nine million board feet of lumber in 1973. By 1987, Louisiana-Pacific also had a sawmill complex at Trinity, with Bill Sanders supervising pine lumber production. By 1990, only one plant was listed in the trade journals.
