The Swalley Irrigation District supplies water to irrigators through a network of pipes and canals fed by the Deschutes River near Bend in the U.S. state of Oregon. The network, begun in 1899, is a closed system with an intake behind North Canal Dam in Bend and a main canal, the Swalley Canal, that runs north from the city for about 13 miles (21 km). The only covered bridge east of the Cascade Range in Oregon crosses the Swalley Canal.
