Who the compiled these figures I do not know. The information was released in 1965. The one item that really caught my attention was the amount of total combined water surface there is/was.

The County of Lassen contains an area of 4,548 square miles or 2,910,296 acres of which 115,840 are covered with inland water. The U.S. Bureau of Land Management controls 1,015,216 acres, the U.S. Forest Service 608,406 acres and ranches cover 744,358 acres.
