About this map

The Payette River anchors this agricultural landscape, where a sophisticated network of water engineering sustains the valley floor. In the Lower Payette Valley, the intricate irrigation system is defined by major arteries like the Emmett Irrigation District North Side-Main Canal, the Farmers Cooperative Canal, and the Black Canyon Canal. These man-made channels work alongside natural features like Sevenmile Slough to transform the arid terrain near the Emmett Bench.

Settlement patterns follow the water and roads, centered around the community of Letha and the smaller locality of Little Rock. Local history is preserved at the Falk Cem, located near the intersection of Graveyard Gulch and the Farmers Cooperative Wasteway. The geography transitions from the flat, cultivated Emmett Valley to the more dissected landforms of Sand Hollow, illustrating the vital role of water management in Idaho's interior development.
