In the mid-1990s, the Colorado Division of Water Resources (CDWR) adopted rules governing measurement of tributary groundwater pumpage for the Arkansas River Basin. The rules allowed groundwater pumpage to be determined using one of two approaches—power conversion coefficient (PCC) or totalizing flowmeters (TFM). In addition, the rules allowed a PCC to be applied to the electrical power usage up to 4 years in the future to estimate ground-water pumpage.
As a result of concerns about potential errors in applying the PCC approach forward in time, a study was done by the U.S. Geological Survey, in cooperation with CDWR and Colorado Water Conservation Board, to evaluate the variability in differences in pumpage between the two approaches, including the effects of time trends.

In March 1994, the Colorado Division of Water Resources (CDWR) adopted ?Rules Governing the Measurement of Tributary Ground Water Diversions Located in the Arkansas River Basin? (Office of the State Engineer, 1994); these initial rules were amended in February 1996 (Office of the State Engineer, 1996).
