2015 Map of Irish Hill

About this map

Irish Hill and Indian Hill anchor the southern landscape of this Amador County region, where the eastern edge of the Sacramento Valley meets the lower foothills. The map reveals a transition from the agricultural plains of Central Valley to a more complex drainage network including Mule Cr and Dry Cr. This 2015 survey details a working landscape defined by ranching infrastructure and water management, evidenced by the Horse Shoe A Ranch Airport and the historical engineering of the Arroyo Seco Ditch. Named landmarks like New York Gulch and Spanish Gulch reflect the area's gold-rush era heritage, even as modern roads like Latrobe Rd and Old Sacramento Rd trace the paths of older thoroughfares. Smaller reservoirs such as Henderson Reservoir and Goffinet Reservoir serve the localized needs of the foothill ranches.
