2012 Map of Trinity Dam

About this map

Trinity Lake dominates this Northern California landscape, its complex shoreline defined by countless arms and gulches like Haylock Gulch and Dutch Gulch. The massive engineering of Trinity Dam at the southeast corner of the lake regulates the Trinity River, while the surrounding terrain is a network of ridges and flats including Telephone Ridge and Red Flat. The map documents a recreational and residential infrastructure that has grown around the reservoir, from established areas like Ridgeville and Estrellita to numerous forest service sites.
