Billings Bench Water Association Canal

The Billings Bench Water Association Canal, also referred to as the Billings Canal and built as the Billings Land & Irrigation Canal, is an irrigation ditch that starts at the Yellowstone River in Laurel, Montana. It runs through Billings, Montana, then flows via tunnel under the Rimrocks into the Billings Heights before ending at the Yellowstone River near Shepherd, Montana.

The nonprofit Billings Bench Water Association (BBWA) has operated the canal since 1915. It is largest ditch in Billings and a crucial water source for agriculture in the area between Billings and the Huntley Project.
