2015 Map of Trinity Dam

About this map

Trinity Lake dominates this rugged portion of the Trinity National Forest, serving as a central geographic feature that dictates the surrounding settlement and road patterns. This 2015 data reflects a landscape defined by water management and recreation, where small communities like Ridgeville, Estrellita, and Fairview are situated near the fingers of the reservoir. The massive Trinity Dam and its lower neighbor, Lewiston Lake, indicate the area's role in California's water infrastructure. Beyond the water, the terrain ascends sharply into the Salmon Mountains and notable peaks such as Pettijohn Mtn. Genealogists and local historians will find the Ridgeville Cemetery and family-named landmarks like Bowerman Ridge or Roycroft Gulch essential for tracking local roots. A network of forest routes, including Haylock Ridge Rd and Montgomery Creek Rd, provides detail on access to remote corners of this mountain landscape.
