Riparian species vegetation classification data for the Colorado River within Grand Canyon derived from 2013 airborne imagery

These data are a species-level classification map of riparian vegetation in the Colorado River riparian corridor in Grand Canyon, Arizona, USA. The classification is derived from 0.2 m pixel resolution multispectral aerial imagery acquired in May 2013. The classification spans the riparian zone of the river corridor between Glen Canyon Dam near Page, Arizona, and Lake Mead at Pearce Ferry, Arizona. The classification is divided into 5 distinct reaches of the river: Glen Canyon, Marble Canyon, Eastern Grand Canyon, Western Grand Canyon upstream of Diamond Creek, and Western Grand Canyon downstream of Diamond Creek. The method used for classification was a combination of supervised Classification And Regression Tree...

Discharge and water temperature data, Lake Powell thermal profiles, and Annual Thermal Units used to assess reintroduction feasibility of Colorado pikeminnow (Ptychocheilus lucius) in the Colorado River in Grand Canyon

These data were compiled to assess the physical attributes of the Colorado River and its tributaries in Grand Canyon, including discharge, water temperature, Annual Thermal Units, and the potential future thermal regime of the river due to climate change. The objective of our study was to assess whether this river reach could support various life stages of Colorado pikeminnow (Ptychocheilus lucius). These data represent discharge and water temperature in the river segment between Glen Canyon Dam and the Lake Mead inflow, as well as data from Lake Powell that drive water temperatures in Grand Canyon. These data were collected in the Colorado River in Grand Canyon from 1/1/1950 to 9/8/2021. These data were collected...

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

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...
