Gibson Jack Idaho 2018 Stream Connectivity Information

This resource includes hydrometric data collected within the Gibson Jack watershed, located in Pocatello, Idaho, USA in the northern Rocky Mountains. These data were collected with the purpose of assessing three-dimensional connectivity in an intermittent stream reach. Stage was measured via Onset U-20 water level loggers at 13 locations within the stream, riparian area, and adjacent hillslopes, and corrected for barometric pressure. For sites within the stream, stage was converted to a hydrograph via a stage-discharge relationship derived from occasional discharge measurements. Discharge measurements were made with a SonTek FlowTracker as well as using dilution gaging methods with an Onset U-24 electrical conductivity logger, which was used to quantify the breakthrough curve for known additions of salt. Local discharge gains and losses in flow along the stream network were calculated using the methods outlined in Payn et al. 2009. Precipitation was measured using a Texas Electronics Rain Gage (0.254mm) recorded by a Campbell Scientific CR1000 datalogger. Temperatures were also recorded at the stream sites using the Hobo U-24 sensors.
