Document Description
This proposed project consists of the replacement of eight existing elevated wood-supported metal flumes along the Nevada Irrigation District (District) DS Canal with steel supported elevated 72-inch pipe flumes. The existing flumes connected 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 Road (to the west). Flumes #13 and #19 are proposed to be replaced in their current alignments, 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 being connected.
