    • Humpback chub (Gila cypha) and mean daily water temperature data, western Grand Canyon - 2000 to 2016

    Metadata Updated: July 6, 2024

    These data were compiled to examine patterns of humpback chub (Gila cypha) in western Grand Canyon from just below Havasu Creek at river kilometer (rkm) 253 (Lees Ferry is rkm 0) downriver to Pearce Ferry at rkm 451. These data represent mean daily water temperatures in degrees Celsius from two USGS gaging locations (2005-2016), catches of individual humpback chub in hoop nets (2005-2016), total lengths of individual humpback chub captured in hoop nets during 2014, 2015 and 2016, and the effort (number of seine hauls) and catch of humpback chub in seines (2000-2016) in the Colorado River. These data were collected by research staff from the Grand Canyon, Monitoring & Research Center, Southwest Biological Science Center during field observations from 2000 to 2016. These data can be used to identify trends in humpback chub catch rates in the mainstem Colorado River downstream of Glen Canyon Dam in Grand Canyon. Long-term monitoring data from both hoop nets and seining was used to document likely local recruitment and population expansion of humpback chub in western Grand Canyon.
