1968 Map of Hewitt Lake

About this map

The Milk River meanders sharply through the northern plains of Montana, creating a complex landscape of oxbows and sloughs that define this 1968 survey. Central to the map is the Hewitt Lake National Wildlife Refuge, a protected sanctuary surrounding Hewitt Lake, which serves as a critical stopover in the Missouri River Basin's hydraulic network. The infrastructure of the era is evident in the sprawling Nelson Reservoir and the carefully engineered Nelson South Canal, highlighting the region's reliance on water management for agriculture and habitat conservation.
