1968 Map of Ruby Lake NW

About this map

The Ruby Lake National Wildlife Refuge dominates this 1960s-era landscape, where a complex network of managed wetlands and sumps is bracketed by the Ruby Mountains and the Maverick Springs Range. The survey reveals a highly specific water-management system divided into areas like North Sump, East Sump, and South Sump, alongside numbered units. This hydrology supports the Gallagher State Fish Hatchery, indicating the region's importance for conservation and resource management during the mid-20th century.
