Annual Reports
Pursuant to the Stipulated Agreement, the Watermaster prepares an annual report that summarizes Watermaster activities, production by the Parties to the Stipulated Agreement, transfers and assignments among the Parties, replenishment and storage activities, Watermaster expenses, and an independent financial audit. The annual reports have evolved from a fairly simple document in the early years of the Watermaster to a more complex document following the adoption of the Peace Agreement in 2000 and the implementation of the Optimum Basin Management Program.

Assessment Packages
Watermaster develops a budget each year to fund its operations in the subsequent year. The budget is reviewed and approved by the Parties to the Stipulated Agreement. Watermaster allocates the costs in the budget to the Parties based on assessment rules contained in the Stipulated Agreement and its amendments, the Peace Agreement and its amendments, and policies adopted by the Watermaster. The assessment package, like the Watermaster Annual Report, has evolved and has become much more comprehensive following the adoption of the Peace Agreement in 2000 and the implementation of the Optimum Basin Management Program.

DYY Agreement Documents
The Dry Year Yield (“DYY”) Program is a large scale storage and recovery program in the Chino Basin with the Metropolitan Water District of Southern California (“MWD”). Under DYY Program, and the agreements that implement it, MWD has the right to store up to 100,000 acre-feet of water in the Chino Basin. Extensive technical analysis was conducted prior to implementation of this program and this information is therefore helpful in order to understand the capabilities and constraints associated with the storage of water in the Chino Basin through the Storage and Recovery Program.

OPTIMUM BASIN MANAGEMENT PROGRAM PEIR
The Optimum Basin Management Program (“OBMP”) is the management plan for the Chino Basin order by the 1978 adjudication Judgment. The OBMP Phase I Report is described above. The OBMP is a comprehensive management plan that serves as the overall blueprint for Basin management decisions by Watermaster. Prior to implementation of the OBMP, extensive review under the California Environmental Quality Act (“CEQA”) was conducted. This review is documented in the OBMP Programmatic Environmental Impact Report (“PEIR”). The OBMP PEIR was certified by the Inland Empire Utilities Agency without objection.

Optimum Basin Management Program Phase 1 Report
The Optimum Basin Management Program Phase 1 report was prepared pursuant to the February 1998 court order that ordered the Watermaster to develop and implement an Optimum Basin Management Program (OBMP). Watermaster conducted an investigation of the current and future groundwater management challenges and developed a water resources management program to overcome these challenges. Watermaster and the Parties developed very precise goals, identified the impediments to these goals, developed detailed programs to remove these impediments, and developed an implementation plan to implement the OBMP.

Peace Agreement Approval Documents
The Peace Agreement Approval Documents include a series of court documents that summarize the process of finalizing and approving the Peace Agreement in 2000. The documents illustrate the professional and business like manner in which the Parties conduct themselves.

Peace II Documents
The Peace II Agreement process started due to a need to resolve the funding for expansion of the OBMP groundwater desalter program. The Peace II Documents include the complete record of court documents and summarize the process of finalizing and approving the Peace II Agreement in 2007. The documents illustrate the professional and business-like manner in which the Parties conduct themselves. The Peace II Documents also include an engineering report that describes the basin management programs included in the Peace II Agreement and the projected response of the Chino Basin.

State of the Basin Reports
Since 2001, Watermaster prepares a State of the Basin report every two years that describes the groundwater conditions in the basin. These reports describe groundwater availability (production, depth to water and storage), artificial recharge, subsidence, water quality and the status of various monitoring and management programs. The findings in the State of the Basin report are based on extensive monitoring and detailed numerical modeling. The latest report available is the draft 2009 report that describes the state of the Chino Basin in 2008.

Subsidence Documents
All groundwater basins experience subsidence to some degree in response to groundwater pumping. The southwestern Chino Basin in the vicinity of the City of Chino experienced differential subsidence in the late 1980s and 1990s that caused ground fissures. With the implementation of the OBMP in 2000, Watermaster conducted extensive investigations on the cause of subsidence in this area and developed a successful subsidence management program that has completely abated subsidence in the southwestern Chino Basin. The two Subsidence Documents folders contain the seminal reports on the technical evaluation and management of subsidence; and they include the court documents that demonstrate the professional and business like manner in which subsidence is managed.

Watermaster Foundation Documents
The seminal foundation document is the 1978 Stipulated Agreement. Other foundational documents include the Post Trial Memorandum prepared after the Court approved the 1978 Stipulated Agreement, Watermaster Rules and Regulations, the 2000 Peace Agreement and associated Implementation Plan and the Final Peace II Documents that contain amendments to the 1978 Stipulated Agreement.
