Evapotranspiration from rapidly growing young saltcedar in the Gila River Valley of Arizona

Estimates of evapotranspiration by young saltcedar, based on energy budget measurements, were made for an unfilled portion of the San Carlos Reservoir in east-central Arizona. Foty-eight days of record were obtained before the site was inundated. The young saltcedar, which had grown from seed earlier in the season , had an average daily evapotranspiration of 5.8 millimeters of water during the period August 17, 1971, to October 3, 1971. Daily values ranged from 9.2 millimeters to a low of 0.23 millimeters which occurred during a stormy day. (USGS)
