1983 Map of Heron Reservoir

About this map

The Tierra Amarilla Grant boundary defines the landscape of this northern New Mexico territory, where the waters of the Rio Chama flow through complex terrain toward the El Vado Reservoir. This 1983 provisional survey shows the established footprint of the Heron Reservoir, a central feature of the Heron Lake State Park. The map documents the localized topography around The Peninsula and The Narrows, illustrating how the man-made lake adapted to the existing canyons and drainages such as Willow Creek and Cañada de la.
