2018 Map of Llano Seco

About this map

Rancho Llano Seco anchor this Sacramento Valley landscape, where the Sacramento River defines the western border between Glenn and Butte Counties. The complex hydrology of the region is evident in the network of waterways including Angel Slough, Campbell Slough, and the Odell Canal. Significant landforms like Ryan Island and Hartley Island sit within the river's path, reflecting the alluvial nature of the terrain. The area's agricultural and conservation character is marked by a grid of rural roads such as Grainland Rd and Seven Mile Rd, alongside the Llano Seco Unit Trail. This map provides a clear record of modern water management and land use, showing how drainage features like Little Butte Cr and Little Chico Cr integrate with named local routes like Old Ferry Rd and Hugh Baber Ln.
