MARION COUNTY — Bob Sanders bumps along the dirt roads of his 1,100-acre ranch in a beat up burgundy Chevrolet Suburban, the engine roaring as his sprawling cattle operation, known locally for its wagyu beef, stretches around him. A shotgun rides in the passenger seat and battered binoculars sit on the dashboard.
The sloping pasture where his rust-colored cows graze gives way to trees that flank a narrow ribbon of water. It doesn’t look like much, just a slow-moving channel threading through sweetgums and cypress, but this 2.6-mile stretch of the Big Cypress Bayou carries a lot of weight — it connects Lake O’ the Pines, the region’s main water supply, to Caddo Lake, the state’s only natural lake.
