1964 Map of Lemon Reservoir

About this map

Lemon Reservoir dominates the eastern drainage of Missionary Ridge, serving as a central catchment for the Florida River and its numerous high-altitude tributaries. Photogrammetric methods from the 1950s and early 1960s captured this landscape of the San Juan National Forest as it was being formally organized for recreation and water management. The map details the construction of the Lemon Dam and the establishment of several forest service sites, including Lemon Dam Campground and Florida Campground. To the north, the terrain transitions into the protected Weminuche Wilderness, where landmarks like Stump Lakes and Lost Lake mark the high basins. The drainage patterns of Coon Creek and Shearer Creek illustrate the complex watershed that defines this section of La Plata County.
