Economic Analysis of Three Crop Conversion Scenarios in Mojave Water Agency's Baja Subarea

By U.S. Department of Interior Bureau of Reclamation Technical Service Center

Issued January 2015

The purpose of this study is to assess the economic feasibility of reallocating farmland in the Baja Subarea to less water intensive crops.  This analysis is representative of full-time farm operations in the area that receive irrigation water from groundwater pumping within the Baja Subarea basin.

Baja Subarea Irrigation Efficiency Analysis

By U.S. Department of the Interior Bureau of Reclamation Lower Colorado Region Southern California Office

Issued November 2014

Provides a description of the methodology and analysis of existing irrigation efficiency rates and potential water savings (reduced production) that could be achieved through improved efficiency in the Baja Subarea.

By Todd Engineers with Kennedy/Jenks Consultants

Issued July 2013
The Baja and Centro Subareas are located in the lower portion of the Mojave River Basin, in the Western Mojave Desert. This Basin Conceptual Model was developed by integrating all previous studies, field investigations, and monitoring programs, providing a scientific foundation for groundwater management. The information presented includes local geology, land use, water use, climate and hydrologic conditions of the region through time. Understanding the hydrogeology and water supply and demand conditions of the Subareas is critical to future groundwater management.

Hydrogeologic Investigation of Camp Cady Wildlife Area, Newberry Springs, CA
Prepared by Todd Engineers
January 2013

This study documents how varying climatic, hydrogeologic, and land use conditions have impacted the native riparian habitat over time, and evaluates the feasibility of restoring local habitat in the main channel with an engineered solution.

Baja Subarea Location and Facilities
Mojave River Pipeline
The Mojave River Pipeline extends approximately 76 miles from the California Aqueduct in the Phelan area to groundwater recharge sites along the Mojave River.  The large-diameter pipeline project was started in 1996 and completed in 2006 to deliver up to 45,000 acre-feet per year to the Mojave Basin Area to offset growing depletion of native water supplies caused by the region's growth and the over pumping of groundwater.  There are four groundwater recharge basins that have been constructed at Hodge, Lenwood, Daggett/Yermo, and Newberry Springs, in addition to a connection at High Desert Power Project in Victorville.

Baja Hydrograph Map
The Mojave Water Agency and United States Geological Survey are working together in a comprehensive program to monitor water levels and maintain historic records throughout the Basin. All wells on the Hydrograph Maps are a part of the MWA Monitoring Program, and have data available to the public at Mojave Water Agency, Data and Maps - Regional Water Levels and USGS National Water Information System Water Data for the Nation. The graphed wells were selected based on spatial and temporal representation of the Basin.
Upstream data is availble for all subareas in the Mojave Water Agency Region, please visit the Subarea Hydrograph Gallery on the MWA website to view these maps.
