1990 Map of Hog Valley

USGS Topo · Published 1990

About this map

Modoc National Forest dominates the eastern high ground of this Lassen County landscape, where the transition from the irrigated ranching of Big Valley to the wooded uplands of Hog Valley is sharply defined. Water management is the primary human footprint here, visible in the extensive network of irrigation infrastructure such as Babcock Ditch and the Gaging Station located along the seasonal watercourses. The presence of Ditch Camp and the Hog Valley Reservoir underscores the long-standing efforts to harness the runoff from the high ridges for valley agriculture.
