Lowline Canal Pipe Project - 2012

Return to the Completed Projects Page

In October 2012, FID converted 14,350 feet of Lowline Canal with 42 and 36-inch diameter pipe, thus fully enclosing the entire canal.  Previous canal failures negatively impacted irrigated agriculture in Hood River County and made District operations very difficult, and often dangerous. The Low Line canal was over a hundred years old. Over the past quarter century, wind, ice, snow storms, floods, falling trees, and upslope landslides caused 18 major canal bank over-toppings and consequent washouts associated with 25 cfs or more plunging over the downslope side of the canal, cutting down steep forest land slopes and flushing tons of soil and high-value timber into West Fork Hood River, mainstem Hood River, and critical Hood basin tributaries. Since 1985, Lowline Canal failures had annually dumped an average of 45,750 cubic feet (2,290 tons) of sediment into the Hood River Basin. FID used DEQ Clean Water State Revolving Funds and Energy Trust of Oregon offsets to design and construct the final Low Line pipeline to ultimately mitigate the effects from such previous losses and inefficiencies.

  • Bank Impact Blowout
    Open canals are susceptible to falling trees, landslides, sink holes, debris clogging, natural disaster, and subsequent overtopping and or blowouts that can cause severe damage to life, property, and environment. Such damage can also cause significant delays in water delivery to agricultural crops. The Lowline canal was built circa 1900.
