Update of the Accounting Surface Along the Lower Colorado River
The accounting-surface method was developed in the 1990s by the U.S. Geological Survey, in cooperation with the Bureau of Reclamation, to identify wells outside the flood plain of the lower Colorado River that yield water that will be replaced by water from the river. This method was needed to identify which wells require an entitlement for diversion of water from the Colorado River and need to be
Hydrologic conditions in the Bill Williams River National Wildlife Refuge and Planet Valley, Arizona, 2000
During a period of sustained base-flow conditions in the Bill Williams River below Alamo Dam in west central Arizona from March to July 2000, the channel of the river through Planet Valley was dry, and the water table sloped almost due west parallel to the main slope of the flood plain. Water from the river infiltrated into the channel bottom at the head of Planet Valley, moved downgradient in the
Identifying wells downstream from Laguna Dam that yield water that will be replaced by water from the Colorado River, Arizona and California
This report summarizes a comprehensive study and development of the method documented in Owen-Joyce and others (2000). That report and one for the area upstream from Laguna Dam (Wilson and Owen-Joyce, 1994) document the accounting-surface method to identify wells that yield water that will be replaced by water from the Colorado River.
Downstream from Laguna Dam, the Colorado River is the source f
Method to identify wells that yield water that will be replaced by water from the Colorado River downstream from Laguna Dam in Arizona and California
Accounting for the use of Colorado River water is required by the U.S. Supreme Court decree, 1964,
Arizona v. California. Water pumped from wells on the flood plain and from certain wells on alluvial
slopes outside the flood plain is presumed to be river water and is accounted for as Colorado River water.
The accounting-surface method developed for the area upstream from Laguna Dam was modified
An accounting system for water and consumptive use along the Colorado River, Hoover Dam to Mexico
An accounting system for estimating and distributing consumptive use of water by vegetation to water users was developed for the Colorado River to meet the requirements of a U.S. Supreme Court decree and used with data from calendar year 1984. The system is based on a water-budget method to estimate total consumptive use by vegetation which is apportioned to agricultural users by using percentages
Meteorological and associated data collected over agricultural fields in Pinal County, Arizona, 1989 and 1990
Data were collected at temporary meteorological stations installed in agricultural fields in Pinal County, Arizona, to evaluate the spatial and temporal variability of point data and to examine how station location affects ground-based meteorological data and the resulting values of evapotranspiration calculated using remotely sensed multispectral data from satellites. Time-specific data were coll
Accounting for Consumptive Use of Lower Colorado River Water in Arizona, California, Nevada, and Utah
In the Colorado River valley between the east end of Lake Mead and the international boundary with Mexico (see figure), the river is the principal source of water for agricultural, domestic, municipal, industrial, hydroelectric-power generation, and recreational purposes. Water is stored in surface reservoirs and in the river aquifer---permeable sediments and sedimentary rocks that fill the lower

Accounting System for Water Use by Vegetation in the Lower Colorado River Valley
The Colorado River is the principal source of water in the valley of the Colorado River between Hoover Dam and the international boundary with Mexico (fig. 1). Agricultural, domestic, municipal, industrial, hydroelectric-power genera-tion, and recreation are the primary uses of river water in the valley. Most of the consumptive use of water from the river occurs downstream from Davis Dam, where wa
