AbstractA method for estimating unmeasured ground-water return flow from water diverted for irrigation is needed to determine consumptive use of water from the lower Colorado River in the Parker area, Arizona and California. Ground-water return flow can be estimated with a water budget of part of the Parker valley under which ground water drains to the Colorado River. Major components of the water budget are surface-water diversions and consumptive use of water by vegetation. Ground-water return flow is the residual of the budget. Application of this method using flow data for 1981 results in a estimate of 15,400 acre-feet of ground-water return flow. The amount of groundwater return flow for 1981 is small in comparison to the amount of surface water that returns to the Colorado River by way of the system of drainage ditches in Parker Valley.
