After the creation of Lake Texoma, cotton acreage had dropped to about 10 percent of its 1934 level, corn had fallen to less than 2 percent, while peanuts had become the third largest crop. By 2001, wheat had become the largest crop, followed by rye, oats, and peanuts.<ref name="EOHC-MarshallCo"/>

Oil and gas production began soon after the county was formed at statehood. Pure Oil Company built an oil camp in 1940 with 43 houses and a 35-bed bunkhouse. Pure closed the camp in 1959 after a 1957 tornado had severely damaged it. At the turn of the 21st century, oil production was about 10 percent of the 1975 quantity, while gas production was about 68 percent of the 1975 quantity.<ref name="EOHC-MarshallCo"/>
