MonitoringLocationName IDUSRL39
MonitoringLocationDescriptionText IDUSRL39 is an irrigation return flow monitoring station on Lateral 39 located on private property within the Twin Falls Irrigation Tract, which is managed by the Twin Falls Canal Company (TFCC), in the Upper Snake Rock watershed. This lateral is a tributary of the Snake River that receives seasonal irrigation return flow, and continuous flow from subsurface drainage within the TFCC. Weekly, the ARS manually measures stream flow over a 5 ft TFCC structure with a weir stick, manually collects a water quality sample, and records the water and air temperature all year. This lateral is an irrigation water supply line and does not correspond with a drainage area.
