About this map

Coglan Buttes dominate the eastern landscape of this Lake County region, rising sharply above the expansive wetlands of the Upper Chewaucan Marsh. The contrast between the high desert rimrock and the intensive water management system below reveals the agricultural history of the basin. A dense network of irrigation infrastructure, including the Red House Ditch, Jones Canal, and ZX Brattain Ditch, crisscrosses the marshland to harness the Chewaucan River. This complex hydrological layout illustrates the long-standing effort to reclaim and utilize the basin's seasonal waters. Higher elevations are marked by landmarks like Shores Waterhole and the descent of Coglan Canyon, while the valley floor is accessed by local routes such as Redhouse Rd and Lovers Ln.
