Agricultural water management and the transition from valley floor to forest highlands characterize this Ravalli County survey. The Bitterroot Irrigation District Canal and Highline Ditch Aqueduct demonstrate the complex engineering required to move water across the landscape, feeding into local works like Ward Ditch. These systems parallel the flow of Skalkaho Creek and Gird Creek as they exit the steep terrain of the Bitterroot National Forest.
