1969 Map of Arrowrock Dam

About this map

Arrowrock Dam anchors this 1969 topographic survey, where the Boise River forms the sprawling Arrowrock Reservoir within the Boise National Forest. This mapping reflects a mid-century landscape managed for water storage and recreational access, shown through the Spring/Shores Recreation Site and Macks Creek Recreation Site. The intricate topography reveals a complex network of drainages such as Sams Gulch and Browns Gulch, which cut through the steep elevations toward the river. To the southwest, the upper reaches of Lucky Peak Reservoir are visible, including the Lucky Peak River channel. Notable land features like Three Point Mountain and Highland Valley provide fixed points for understanding the area's relief. This sheet also records local boundaries between Ada, Boise, and Elmore counties, as well as more localized features like the Wood Creek Enclosure and numerous jeep trails navigating the backcountry.
