of Castle Creek where most of the streamflow is routed into a sluice which then enters a 1.8 mile-long (2.9 km) pipe and is ultimately delivered to a farm’s irrigation headworks lower in the valley. The natural river channel is mostly dry for the next two miles until the point where excess water is returned to the creek.
Two observations: 1) It’s not exactly a healthy riparian system, and 2) blue tarps have limitless applications.
