Dry Creek Recapture Project Description:
Browns Valley Irrigation District (BVID) is proposing a tailwater recapture project (“Project”) that will relieve irrigation water supply constraints by pumping water from French Dry Creek (“Dry Creek”) at times when Dry Creek flows are primarily composed of tailwater from irrigated lands draining to Little Dry Creek. It is estimated that this influx of tailwater raises Dry Creek’s temperature by an average of 4-5° Celsius and introduces sediment, nutrients, and other constituents into the Creek approximately 1.8 miles upstream of its confluence with the Yuba River. By pumping from Dry Creek downstream of the confluence with Little Dry Creek, the project will remove some of the thermal and pollutant load from the Creek before it reaches the Yuba River.
This warmer reclaimed water will be delivered into BVID’s Pipeline Canal and applied by its customers to rice lands where the elevated water temperature benefits rice production. Application of tailwater recaptured from Dry Creek to the agricultural lands within BVID will reduce the District’s demand for water diverted directly from the Yuba River. Therefore, the Project will balance the reduction in inflow to the Yuba River from Dry Creek with an equivalent reduction in direct diversions from the Yuba River. The Project proposes to recapture up to a maximum of 10 cfs of irrigation return flow from Dry Creek during the irrigation season, which typically runs from April through October.
The Project includes construction of a collection system consisting of a collection chamber, electric pump, and infiltration gallery, near and under Dry Creek; and installation of approximately 11,000 linear feet of underground pipeline with its terminus in an existing irrigation canal known as the Pumpline Canal, which is fed by BVID’s existing Yuba River pumping station. The proposed pipeline will be 24 inches in diameter and will generally run parallel to Dry Creek and the Yuba River. The proposed Dry Creek pumping station location and pipeline alignment are above both the high water mark and floodplain of Dry Creek and the Yuba River. Installation of the underground pipeline will require a construction zone 30 feet in width, which will generally be 15 feet on either side of the route’s centerline. Construction of the Project will necessitate selective removal of some trees and other native and non-native vegetation along the pipeline route. The total disturbed area is estimated to be 7.58 acres.
The inlet to the tailwater recapture pipeline will be located along Dry Creek near the Highway 20 bridge. The collection system, as currently designed, will utilize an infiltration gallery to draw water from Dry Creek. The infiltration gallery will be installed by trenching from the pumping plant location to and under Dry Creek. Installation of the infiltration gallery and intake pipe will require a 100-foot construction corridor from the Creek to the pumping station. A small pumping station will lift the water from the Dry Creek infiltration gallery over the high point in the pipeline alignment and deliver it to the head of the Pumpline Canal. The pumping station will consist of two electric pumps housed in an enclosed structure.
