DS Canal Flume Replacement Project

DS Canal Flume Replacement Project

This proposed project consists of the replacement of 8 existing elevated wood-supported metal flumes along the Nevada Irrigation District DS Canal with Steel supported elevated 72 inch pipe flumes, and replacement of an existing culvert at Gracie Rd. The existing flumes connect the DS Canal, where it spans natural drainages, to provide gravity flow along the course of the canal. The flumes proposed for replacement are generally located between the DS Canal's intersections with Banner Mountain Trail (to the east) and Banner Lava Cap Rd (to the west). Flumes #13 and #19 is proposed to be replaced in its current alignment, requiring a temporary canal outage while construction takes place. Construction of Flumes #13 and #19 would occur during the non-irrigation season. Flumes #14, 15, 16, 17, 18, and 23 are currently scheduled to be constructed parallel to the existing facilities, on the downslope side, and will require a brief canal outage while they are baing connected.
