Municipal Service Review and Sphere of Influence Update
For the Oakdale Irrigation District
Introduction
The Cortese/Knox/Hertzberg Local Government Reorganization Act of 2000 Act (CKH Act)
requires the Local Agency Formation Commission (LAFCO) to update the spheres of influence
(SOI) for all applicable jurisdictions in the County. A sphere of influence is defined by
Government Code 56076 as “...a plan for the probable physical boundary and service area of a
local agency, as determined by the Commission.” The Act further requires that a municipal
service review (MSR) be conducted prior to or, in conjunction with, the update of a sphere of
influence (SOI).
The legislative authority for conducting a municipal service review is provided in Government
Code Section 56430 of the CKH Act. The Act states, that “in order to prepare and to update
spheres of influence in accordance with Section 56425, the commission shall conduct a service
review of the municipal services provided in the county or other appropriate area...” MSRs must
have written determinations that address the following factors in order to update a Sphere of
Influence. These factors were recently amended to include identification of disadvantaged
unincorporated communities within or contiguous to the sphere of influence of an agency.
Municipal Service Review Factors to be Addressed
1. Growth and population projections for the affected area
2. The location and characteristics of any disadvantaged unincorporated communities
within or contiguous to the sphere of influence
3. Present and planned capacity of public facilities, adequacy of public services, and
infrastructure needs or deficiencies including needs or deficiencies related to sewers,
municipal and industrial water, and structural fire protection in any disadvantaged,
unincorporated communities within or contiguous to the sphere of influence
4. Financial ability of agencies to provide services
5. Status of, and opportunities for, shared facilities
6. Accountability for community service needs, including governmental structure and
operational efficiencies
7. Any other matter related to effective or efficient service delivery, as required by
commission policy
State Guidelines and Commission policies encourage cooperation among a variety of
stakeholders involved in the preparation of a municipal service review. This MSR will analyze
the existing and future services for the Oakdale Irrigation District, located in the northeastern
portion of the County. The current update serves to comply with Government Code Section
56425 and will reaffirm the SOI for the District.

Sphere of Influence Update Process
A special district is a government agency that is required to have an adopted and updated
sphere of influence. Section 56425(g) of the CKH Act calls for spheres of influence to be
reviewed and updated every five years, as necessary. Stanislaus LAFCO processes municipal
service reviews and sphere of influence updates concurrently to ensure efficient use of
resources. For rural special districts, which do not have the typical municipal-level services to
review, this document will be used to determine what type of services each district is expected
to provide and the extent to which they are able to do so. For these special districts, the
spheres will delineate the service capability and expansion capacity of the agency, if applicable.

Municipal Service Review – Oakdale Irrigation District
Authority
The Oakdale Irrigation District was organized under the Wright Act and operates under Irrigation
District Law, Division 11 of the Water Code, Section 20500 et. seq. In addition, the District is
considered to be a “registered voter district”, as the board of directors is elected by registered
voters from five geographical divisions within the District’s boundaries.
Background
Throughout the years, water and California have been linked. No resource is more vital to
California than water, from the agricultural areas, urban centers, and industrial plants to open
space and recreational areas, the distribution of water has been critical to all land uses.
In California, there are hundreds of special water districts with a great diversity of purposes,
governance structures, and financing mechanisms. Some districts are responsible for one type
of specific duty, while other districts provide multiple public services, as is the case for the
Oakdale Irrigation District.
Purpose
Irrigation districts are formed for the provision of sufficient water in the district for any beneficial
use. An irrigation district has the power to control, distribute, store, spread, sink, treat, purify,
recapture, and salvage any water including, but not limited to, sewage waters for beneficial use
of users of the district or its inhabitants. A district may also provide for flood control and can
engage in the generation, transmission, distribution, sale and lease of electric power (Water
Code Section 22075-22186).
Formation
The Oakdale Irrigation District (OID) was formed on November 1, 1909.
Governance
A five-member Board of Directors governs the District. Registered voters within a geographical
area or “Division”, elect the board members. Meetings are held on the first Tuesday of every
month at 9:00 a.m. in the District office located at 1205 East “F” Street in Oakdale. All meetings
are open to the public. Agendas are prepared and posted 72-hours prior to the board meeting
and posted on the bulletin board at the District office and on the District website
(www.oakdaleirrigation.com). Information such as the history of the District, current Board
agendas, water updates, and quarterly newsletters is readily available on the District’s website
as well.
Location and Size
The majority of the District is located in northeastern Stanislaus County. The District also covers
territory in San Joaquin County. The District boundaries comprise approximately 82,000 acres.
The District maintains more than 330 miles of laterals, pipelines, and tunnels, 25 production
wells, and 41 reclamation pumps.
MSR & SOI Update – Oakdale Irrigation District Page 3
Sphere of Influence
The District’s existing Sphere of Influence incorporates approximately 160,800 acres (or 78,800
acres beyond the existing District boundaries). The city limits of Oakdale and the
unincorporated communities of Knights Ferry and Valley Home are located within the District’s
Sphere of Influence. However, the city limits of Riverbank are excluded from the westerly
portion of the District’s SOI, as these areas were detached upon annexation to the City. A map
outlining the District’s boundaries and SOI is attached under Appendix “B”. This Service Review
is intended to cover the District’s existing boundary and Sphere of Influence area.
Personnel
The District currently has 80 full-time employees.
Classification of Services
The District is authorized to provide the functions or classes of services (e.g. irrigation, domestic
water, and electrical power) as identified in this report. Due to recent changes in the Cortese-
Knox-Hertzberg Act, the District would have to seek LAFCO approval to exercise other latent
powers (i.e. services) not currently provided by the District.
Services
OID currently provides agricultural irrigation and domestic water services to its customers. The
District’s water supply comes from the Stanislaus River (under well-established water rights),
recapture of drainage water, and pumping from deep groundwater wells. The District’s
distribution systems include the Goodwin Diversion Dam on the Stanislaus River below the
Tulloch Dam, at which point water is diverted into the District’s main canal systems.
The District is also a wholesale power distributor through its Tri-Dam Project. The Oakdale
Irrigation District and the South San Joaquin Irrigation District (SSJID) jointly own and operate
storage reserves (Tri-Dam Project) and have storage rights in the federally-owned New Melones
Reservoir. The two Districts, under the Tri-Dam Project, own, operate, and maintain three
hydro-electrical power facilities: one each at Donnells Reservoir, Beardsley Lake, and Tulloch
Lake. The Tri-Dam Project’s principal activities are the storage and delivery of water to each
District and the hydraulic generation of power.
Starting in January 1, 2014, the Districts entered into a power purchase and sale agreement
with the City of Santa Clara, California, through its municipal electric utility, Silicon Valley Power.
Under the agreement, the Districts agreed to sell the net electrical output and installed capacity
of its power generating facilities to the City of Santa Clara through December 31, 2023. A new
agreement was recently executed with the City of Santa Clara for an additional 5 year term
ending December 31, 2028.
Additionally, through the Tri-Dam Power Authority (Authority), the two Districts own, operate,
and maintain the Sand Bar Project, a hydro-electric facility downstream of Beardsley Lake which
became operational in 1986. The Authority, on January 1, 2017, entered into a power purchase
and sale agreement with the City of Santa Clara, California as well through its municipal electric
utility, Silicon Valley Power.
MSR & SOI Update – Oakdale Irrigation District Page 4
The District also manages several domestic water systems, which are part of six private and
publicly-owned systems that exist in an unincorporated area east of the City of Oakdale. One of
the systems is owned by OID, while five of the systems are owned by homeowner groups who
have entered into an “improvement district” arrangement with OID to manage their water
systems for State compliance.
Support Agencies
The District maintains positive and collaborative relationships with other agencies, such as:
South San Joaquin, Merced, Modesto, and Turlock Irrigation Districts, Stockton East Water
District, Stanislaus County, City of Oakdale, Oakdale Rural Fire Protection District, City of
Riverbank, Pacific Gas and Electric (PG&E), State Water Resources Board, Bureau of
Reclamation, California Department of Water Resources (DWR), Association of California Water
Agencies (ACWA), California Special Districts Association (CSDA), the Stanislaus and
Tuolumne Rivers Groundwater Basin Association Groundwater Sustainability Agency, and the
Eastern San Joaquin Groundwater Authority.
Funding Sources
The majority of the District’s revenue is from power sales as a result of OID and South San
Joaquin Irrigation District’s Tri-Dam Project and Tri-Dam Power Authority. Other sources
include income from water transfers, irrigation water sales, County property tax appropriations,
interest revenue, and domestic water revenue.
MSR & SOI Update – Oakdale Irrigation District Page 5
Service Review Categories & Determinations
The following provides an analysis of the seven categories or components required by Section
56430 for a Service Review for the Oakdale Irrigation District:
1. Growth and Population Projections for the Affected Area
The Oakdale Irrigation District currently serves over 2,900 customers with irrigation water for
agricultural purposes and approximately 767 customers with domestic water for residential
purposes. For many years, the District has provided irrigation water on an annual basis for
20 to 30 out-of-district agreements, depending on interest and water availability. After
completing the environmental analysis (CEQA) in January 2023, a 10-Year Out-of-District
Water Sales Program (Program) was initiated. Approximately 10,000 irrigated acres have
enrolled in the Program to be delivered surface water from the District when water is
available under its pre-1914 water rights without any impact to OID’s in-district constituents.
The District updates its customer records as necessary for billing purposes. Part of that
update includes parcel size, location, and crop type on lands served with OID water. As
land use conversions take place, the water needs of OID’s customer base can substantially
change. This information, combined with data from the Department of Water Resources, the
Department of Finance, and the U.S. Census Bureau allows the District to develop land use
trends and forecasts. While irrigated lands will continue to be lost due to urbanization by the
City of Oakdale, the City may be interested in surface water as a source of supply in the
future and the increase in irrigated agriculture outside the current District boundaries
provides opportunity for District expansion.
2. The Location and Characteristics of Any Disadvantaged Unincorporated Communities
Within or Contiguous to the Sphere of Influence
Under Government Code Section 56033.5, “disadvantaged unincorporated community” is
defined as an inhabited territory (12 or more registered voters), or as determined by
commission policy, with an annual median household income that is less than 80% of the
statewide annual median household income. Upon review of available Census data, and
identified communities in the County, no disadvantaged unincorporated communities were
found within or contiguous to the District’s Sphere of Influence.
3. Present and Planned Capacity of Public Facilities, Adequacy of Public Services, and
Infrastructure Needs or Deficiencies Including Needs or Deficiencies Related to
Sewers, Municipal and Industrial Water, and Structural Fire Protection to Any
Disadvantaged, Unincorporated Communities Within or Contiguous to the Sphere of
Influence
OID’s existing and planned public facilities and services are designed to supply irrigation
and related drainage with the priority of serving those properties within District boundaries
prior to out-of-district approvals. In 2007, the District completed a Water Resources Plan
(WRP). The WRP evaluated the District’s water resources, facilities, and operations. It
provides specific, prioritized recommendations for OID physical and operational
improvements as well as a plan to phase the implementation of improvements consistent
with available financial resources.
MSR & SOI Update – Oakdale Irrigation District Page 6
In accordance with the requirements of the Water Conservation Act of 2009 (SBx7-7) and
the Governor’s Executive Order B-29-15, OID prepared a 2015 Agricultural Water
Management Plan (AWMP). A Water Resources Plan Report Card section was added to
OID’s 2015 AWMP to provide a review of improvement actions identified under the WRP, a
summary of actions completed and projections of near- and long-term actions to be
completed.
As indicated previously, there are no disadvantaged unincorporated communities within or
contiguous to the City’s Sphere of Influence.
4. Financial Ability of Agencies to Provide Services
In 2021, power generation from both the Tri-Dam Power Project and the Tri-Dam Power
Authority accounted for approximately 50 percent of the District’s total revenue. Water
transfer agreements and agricultural water delivery charges contributed approximately 24
percent of the net revenue, while County property tax appropriations accounted for 19
percent. Domestic water charges provide only a slight contribution to the District’s total
revenue.
The District’s adopted Water Resources Plan (WRP) includes a financial plan to achieve
infrastructure and modernization needs currently identified by the District. The District has
completed more than $100 million of improvements and annexed +/-10,500 acres since the
start of implementation of the WRP. Total project costs by implementation category through
2019 are summarized in OID’s 2020 AWMP. Annexation provides additional funding to
finance various infrastructure and operational improvements under the WRP while providing
additional benefits of decreased reliance on groundwater for irrigation and increased
groundwater recharge from deep percolation of surface water used for irrigation. The WRP
identified a goal for annexation of approximately 4,250 acres within the OID sphere of
influence by 2020 as part of preferred alternative. The District’s WRP annexation goals
have already been surpassed.
OID appears to be financially sound with strong and stable sources of revenue, substantial
reserves, and a superior credit rating. The District’s long-range planning programs allow the
District to plan and budget for needed improvements to services and facilities in a balanced
way that is consistent with its anticipated revenue. The District’s budget process is
designed to screen out unnecessary costs and is submitted to the Board of Directors for
review and approval.
5. Status of, and Opportunities for, Shared Facilities
The District and the South San Joaquin Irrigation District jointly own and operate three
storage reservoirs (Tulloch, Beardsley, and Donnells). The District also jointly owns,
operates, and maintains the Donnells, Beardsley, and Tulloch power plants along with a
separate power facility (Sand Bar Project) with the South San Joaquin Irrigation District. In
addition, both Districts own, operate and maintain the Joint Main Canal running along the
north side of the Stanislaus River Canyon. This canal carries 100% of South San Joaquin
Irrigation District’s water to its service area and provides 40% of OID’s deliveries for those
lands within its boundaries north of the Stanislaus River.
MSR & SOI Update – Oakdale Irrigation District Page 7
The District has also contributed funding to the City of Oakdale for water safety and water
conservation programs; to the Oakdale Fire Department for water rescue training and
materials; and to the Oakdale Rural Fire Protection District for a new water rescue boat.
Under a development agreement, the District shares eight water wells with the Oakdale
Rural Fire Protection District, which allows the fire district to refill their fire trucks during
emergencies. The District also has a joint easement with the City of Oakdale for the
Burchell Hills Specific Plan Area Bike Path. Additionally, OID is working with the City of
Oakdale to utilize surface water to irrigate City parks as well as evaluating options for and
the feasibility of recycling tertiary treated M&I discharge from the City in OID’s system for
agricultural irrigation and groundwater recharge.
6. Accountability for Community Service Needs, Including Governmental Structure and
Operational Efficiencies
A five-member Board of Directors governs the District. Registered voters within a
geographical area or “Division”, elect the board members. The Board conforms to the
provisions of the Brown Act requiring open meetings. The District also has established a
website (www.oakdaleirrigation.com) that is user-friendly and provides information such as
the history of the District, current Board agendas, water updates, and newsletters.
The District has the necessary resources and staffing levels to operate in a cost-efficient
and professional manner. It is reasonable to conclude that the District has the
organizational capability to adequately serve the areas under its jurisdiction.
7. Any Other Matter Related to Effective or Efficient Service Delivery, as Required by
Commission Policy
Improvements under the WRP include canal maintenance and rehabilitation, flow control
and measurement, groundwater well replacement, pipeline replacement, regulating reservoir
construction, turnout maintenance and replacement, outflow management projects (i.e.
spillage and runoff reduction and reuse), reclamation projects, Supervisory Control and Data
Acquisition (SCADA) system expansion and annexation. A few current projects to note
include the District’s Phase 1 Total Channel Control (TCC) Modernization Project and the
Two-Mile Bar Tunnel Project. The $6.5 million project Phase 1 TCC Modernization Project,
with up to $3 million in matching funds from the Department of Water Resources through the
Proposition 1 Water Quality, Supply and Infrastructure Act of 2014, provides the complete
automation of approximately 18 miles of OID’s open canal system. The District’s Two-Mile
Bar Tunnel Project, a new 5,949 linear foot tunnel for water conveyance, was completed
and operational before the 2019 irrigation season (+/-March 2019). The tunnel alignment
bypasses roughly 7,200 linear feet of high hazard rock fall and canal creep failure sections
of the OID’s existing South Main Canal.
Consistent with the goals of the WRP, these projects along with the rest of the $100 million
of improvements since the start of its implementation, improve water supply reliability while
also improving operability and operation of the system. The quality of water delivery
services to customers continues to improve with OID’s ability to offer greater flexibility in the
frequency of deliveries along with a steadily maintained flow rate at the water delivery point.
MSR & SOI Update – Oakdale Irrigation District Page 8
Sphere of Influence Update
In determining a sphere of influence (SOI) of each local agency, the Commission shall consider
and prepare determinations with respect to each of the following factors, pursuant to
Government Code Section 56425:
1. The present and planned land uses in the area, including agricultural and open-space
lands.
2. The present and probable need for public facilities and services in the area.
3. The present capacity of public facilities and adequacy of public services that the agency
provides or is authorized to provide.
4. The existence of any social or economic communities of interest in the area if the
commission determines that they are relevant to the agency.
5. For an update of a sphere of influence of a city or special district that provides public
facilities or services related to sewers, municipal and industrial water, or structural fire
protection, the present and probable need for those public facilities and services of any
disadvantaged unincorporated communities within the existing sphere of influence.
The following determinations for the Oakdale Irrigation District’s Sphere of Influence update are
made in conformance with Government Code Section 56425 and local Commission policy.
Determinations:
1. Present and Planned Land Uses in the Area, Including Agricultural and Open-Space
Lands
The Oakdale Irrigation District’s current boundary is comprised of approximately 82,000
acres, with a Sphere of Influence (SOI) area that encompasses 160,800 acres (78,800+/-
acres beyond the existing District boundary). The land uses within the District’s existing
boundaries and Sphere of Influence consist of agricultural, rural residential, suburban and
urban land use areas. These uses are not expected to change, except in the Spheres of
Influence of the cities of Oakdale and Riverbank. In addition, the District does not have the
authority to make land use decisions, nor does it have authority over present or planned
land uses within its boundaries. The responsibility for land use decisions within the District
boundaries is retained by Stanislaus, Calaveras, San Joaquin counties, and the cities of
Oakdale and Riverbank.
2. Present and Probable Need for Public Facilities and Services in the Area
The District has developed a Water Resources Plan (WRP) to address the District’s water
resource needs into the future. Components of the Plan include: public outreach, resource
inventory (surface, groundwater), water balance, infrastructure plan, and water rights
portfolio. The WRP also projects the reasonable number of acres within the SOI that could
be annexed to OID’s boundaries while maintaining service levels to existing lands within the
District’s boundaries.
MSR & SOI Update – Oakdale Irrigation District Page 9
The present and probable need for the District’s ability to continue to provide public facilities
and services in the area is affected by the fact that the cities of Oakdale and Riverbank’s
Spheres of Influence overlap into the District. In addition, the District has a diminishing
Sphere of Influence in that as territory annexes to the City of Riverbank, it detaches from the
District.
The District’s Sphere of Influence excludes some territory within the current city limits of
Riverbank. Back in 2004 OID was advised by the State of California Department of Health
Service of the legal requirements (CCR Title 17). The cross-contamination compliance
responsibility under the law (CCR 17, Article Vii, Sec 35-50(a)) rested with the City providing
the domestic water services. Upon contacting the City of Riverbank, and through
discussions with them, it was agreed to discontinue raw water services of OID within the City
limits of Riverbank. Later a policy was developed by OID to curtail raw water services to any
territory annexed by a City.
Development of lands not currently in the OID service area may lead to future annexations
within the Sphere of Influence as appropriate. Consistent with LAFCO policies, in order to
annex additional territory, the District must provide and/or demonstrate that there are
sufficient quantities of water to serve additional territory without affecting the present service
area and/or existing customers. The availability of current water supplies each year is
affected by numerous factors, including annual rainfall and snowfall, and environmental
factors such as: climate demand, water conservation efforts, crop changes, contractual
obligations for water transfers, etc.
3. Present Capacity of Public Facilities and Adequacy of Public Services that the
Agency Provides or is Authorized to Provide
The District has strong surface water rights, including annual diversion rights from the
Stanislaus River of 300,000 acre-feet (normal year). The District utilizes a Surface Water
Shortage Policy in order to address service delivery issues during times when the quantity of
water right available to the District is insufficient to meet the water demands of the crops
grown.
As part of the Water Resources Plan (WRP), the District selected an alternative which
focuses on maximizing improvements in the District and provides for moderate expansion in
the SOI. Since the WRP’s adoption in 2007, the District has been actively investing in its
canal system based on improvement needs, as prioritized in the WRP. The improvements
are intended to enhance customer service, use water more efficiently, increase reliability
and drought protection, and reduce the amount of water leaving the District without benefit
to OID customers.
4. The Existence of Any Social or Economic Communities of Interest in the Area if the
Commission Determines That They are Relevant to the Agency
The following jurisdictions can be categorized as communities of interest in the area: the
cities of Oakdale and Riverbank, and the unincorporated communities of Knights Ferry,
Valley Home, and the rural residential area known as East Oakdale. The Spheres of
Influence for both the City of Oakdale and Riverbank overlap into the District’s boundaries,
which may affect the District’s ability to provide services to these areas as urbanization
occurs.
MSR & SOI Update – Oakdale Irrigation District Page 10
5. For an Update of a Sphere of Influence of a City or Special District That Provides
Public Facilities or Services Related to Sewers, Municipal and Industrial Water, or
Structural Fire Protection, the Present and Probable Need for Those Public Facilities
and Services of Any Disadvantaged Unincorporated Communities Within the Existing
Sphere of Influence
The District manages several domestic water systems, which are part of six private and
publicly-owned systems that exist in an unincorporated area east of the City of Oakdale.
However, as discussed in the District’s Municipal Service Review, there are no identified
disadvantaged unincorporated communities within the existing Sphere of Influence or the
proposed expansion area.
