COID canal piping boosts Madras-area farm deliveries, Crooked River flows iStock/Deschutes River Conservancy Section of the Crooked River that will benefit from COID canal piping project BEND, Ore. (KTVZ) -- The Central Oregon Irrigation District said Friday it has received final approval from the Oregon Water Resources Department for the West-F project that piped 2,210 feet of a leaky lateral canal north of Redmond. As a result, the 1,602 acre-feet of water saved by COID have been transferred to about 649 acres of farmland in the North Unit Irrigation District near Madras, the area’s most junior water users. The equivalent amount of water was then transferred from NUID into the Crooked River.
