LAFCO Resolution 2008-0004 – Municipal Service Review
LAFCO Resolution 2008-0007 – Sphere of Influence
1. INTRODUCTION
1.1 LAFCO's Responsibilities
This Municipal Service Review (MSR) has been prepared for the Colusa Local Agency
Formation Commission (Colusa LAFCO). Local Agency Formation Commissions are
quasi-legislative local agencies created in 1963 to assist the State in encouraging the
orderly development and formation of local agencies. This MSR consists of a review of
water service as provided by the Holthouse Water District.
The Cortese-Knox-Hertzberg Local Government Reorganization Act of 2000
(Government Code §56000, et seq.) is the statutory authority for the preparation of an
MSR, and periodic updates of the Sphere of Influence of each local agency. The
Governor’s Office of Planning and Research has issued Guidelines for the preparation of
an MSR. This MSR adheres to the procedures set forth in the MSR Guidelines.
A Sphere of Influence is a plan for the probable physical boundaries and service area of a
local agency, as determined by the affected Local Agency Formation Commission
(Government Code §56076). Government Code §56425(f) requires that each Sphere of
Influence be updated not less than every five years, and §56430 provides that a Municipal
Service Review shall be conducted in advance of the Sphere of Influence update.
1.2 Municipal Service Review Requirements
The statute as amended by AB1744 and regulations call for a review of the municipal
services provided in the county or other appropriate area designated by the LAFCO. The
LAFCO is required, as part of the MSR, to prepare a written statement of findings of its
determinations with respect to each of the following:
1. Growth and Population
2. Capacity and Infrastructure
3. Financial Ability
4. Shared Facilities
5. Government Structure and Accountability
1.3 Sphere of Influence Requirements
In determining the Sphere of Influence for each local agency, LAFCO must consider and
prepare a written statement of determinations with respect to each of the following:
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;
Holthouse Water District - Adopted March 6, 2008 1
LAFCO Resolution 2008-0004 – Municipal Service Review
LAFCO Resolution 2008-0007 – Sphere of Influence
3. The present capacity of public facilities and adequacy of public services which the
agency provides, or is authorized to provide; and
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.
2. SETTING
2.1 Colusa County
Colusa County is located approximately thirty-five miles north of Sacramento, along the
I-5 corridor. The County is approximately thirty-five miles long (north to south) and
forty-five miles wide (east to west). It is bounded by Yolo, Sutter, Butte, Glenn and Lake
Counties.
It is primarily a rural agricultural county, with a total population of about 17,000. There
are two incorporated cities: Colusa (5,000) and Williams (3,000). Interstate 5 bisects the
County running north and south.
To the west of I-5 is flat agricultural land, running into the Coastal Mountain range. The
highest point in the County is located in the Coastal Range, at over 7000 feet. East of I-5,
the topography is flat. The Sacramento River roughly forms the eastern boundary of the
County.
Agriculture is the major industry in the County. Colusa was identified by UC Davis
Cooperative Extension Specialist Al Sokolow as having the highest percentage increase
in agricultural growth in California during the period 1985-1995 (115% increase).
The total on-farm agricultural value in the county in 1997 was $333 million. The major
crops produced include rice, processing tomatoes, almonds, wheat, vegetable seeds,
walnuts and prunes. Land is relatively inexpensive and water is both available and high
quality, compared to other California locations.
While the environment defines the breadth of crops produced locally, agriculture is
clearly increasing in importance. Rice remains the number one crop, with acreage
remaining fairly stable. There is currently a transition from row crops to perennial crops
(almonds, grapes, walnuts) and from low-value agronomic crops to higher value
vegetables or other row crops.
Environmental issues (air quality, water quality, soil degradation, etc.), commodity
marketing and economic sustainability are the major challenges facing local producers.
The rural nature, low population and ethnic makeup of Colusa County all contribute to
"quality of life" issues. There are not many organized activities or employment

LAFCO Resolution 2008-0007 – Sphere of Influence
opportunities for young people, so the local youth become bored with the community and
emigrate after graduating from high school.
Retention of young people is one of the biggest problems, as the current producers retire
or exit farming. Owing to a small consumer base, local merchants have difficulty
remaining in business and many residents export money out of Colusa by shopping in
neighboring counties. Economic development is a high community priority.
The school-age youth in the County are over 50 percent Hispanic, one of the highest in
the state. Cultural barriers, communication skills and community infrastructure to support
this segment of the citizens are all major challenges.
The unemployment rate is often the highest in the state (reaching over 30% during the
winter months). The per capita income is among the lowest.1
2.2 Colusa County Population
The 2006 population of Colusa County is estimated at 21,272, a 13.1% increase from
2000. This is nearly double the 7.6% increase for the State.2
The age distribution of the Colusa County population in 2005 as compared to that of
California is shown below:
Colusa California
Under 5 years old 8.0% 7.4%
Under 18 years old 29.1% 26.9%
65+ years old 13.0% 10.7%3
Colusa County has more younger and more older members of the population than the
State. This creates a greater burden on both workers and tax-payers in the County.

In 2005 the residents of Colusa County identified themselves as follows, compared to the
residents of the State:
Race Colusa California
White 93.5% 77.0%
Black 1.0% 6.7%
American Indian 2.4% 1.2%
Asian 1.7% 12.2%
Pacific Islander 0.7% 0.4%
Two or more races 0.6% 2.4%
TOTAL POP. (rounded to nearest tenth) 99.9% 99.9%
Hispanic or Latino Population 49.1% 35.2%4
The 2000 educational level of the Colusa County Population is lower than that of the
State as a whole with 64.0% (of population aged 25 or older) High School graduates
compared to 76.8% Statewide, and 10.6% Bachelor's degree or higher compared to
26.6% Statewide.5
The Median household income in 2004 was $38,350, compared to $49,894 Statewide.6
3. HOLTHOUSE WATER DISTRICT
3.1 Location and History
The District is located in northern Colusa County west of I-5, west of McDermott Road,
northwest of Maxwell. Part of the land in the District has been planted to almond orchard
in the past five years.
Holthouse Water District was created in 1977.7 It is a subcontractor under the Colusa
County Master Water Contract with the Bureau of Reclamation. The District has 1,860
acres8 and a water allocation of only 2,450 acre feet from the Tehama-Colusa Canal. This
is only slightly more than one acre-foot of water per acre of land but many crops require
two to three acre-feet of water per growing season.9

LAFCO Resolution 2008-0004 – Municipal Service Review
LAFCO Resolution 2008-0007 – Sphere of Influence
There are three landholders: Leo Holthouse, Allen Etchepare, and Jean Etchepare. There
are no residents in the District.
Contact information for the District is as follows:
Holthouse Water District
PO Box 658
Maxwell, CA 95955
(530) 438-2850
The District has three Board members, Leo Holthouse, Allen Etchepare and Jim Rickert.
In December 2007, Leo Holthouse will leave the Board and be replaced by his son-in-
law, Ron Lee. Jean Etchepare is the District Secretary.10 The District has a Board
meeting each December. There is no formal budget but the landowners farming the land
pay the expenses.11
3.2 Water Supply
Water for the Holthouse Water District is stored in the Shasta Reservoir behind Shasta
Dam constructed by the Bureau of Reclamation. The Water flows down the Sacramento
River where it is diverted to the Tehama-Colusa Canal and thence conveyed to the
Holthouse Water District.
The system was designed to divert water from the Sacramento River into the settling
basin by virtue of a dam across the Sacramento River located in Red Bluff, California.
And although the system operated in this manner for some years, environmental concerns
and regulatory requirements have altered the operational practices of the dam.
Where, at one time, the dam could be counted on to divert water as early as March,
current regulations generally prevent the dam gates from being lowered until May 15th.12
To overcome this limitation and provide water to irrigators, the Bureau of Reclamation
installed three pumps in the latter half of the 1990's, each with a capacity of between 80
and 100 cubic feet per second (cfs), with provisions for the placement of a fourth pump.
The installation of the fourth pump occurred in 2006. However, irrigation demand can
reach between 800 and 1000 cfs before May 15th, when the dam becomes operational.

LAFCO Resolution 2008-0004 – Municipal Service Review
LAFCO Resolution 2008-0007 – Sphere of Influence
To make up for the shortfall, current practice is to dam up Stony Creek in Orland and
back-flow water through canal gates that were actually intended to let water out of the
canal into Stony Creek. Between the pumps on the Sacramento River at Red Bluff, and
the reverse flow diversion at Stony Creek, the demands of irrigators have been met, but
generally without any reserve.13
Holthouse Water District has a contract with the US Bureau of Reclamation total of 2,450
acre feet annually. This number is subject to Reclamation's yearly allocation.
Reclamation makes the allocations based on several factors, such as how much rainfall,
water in the reservoirs, snow pack, et cetera.
In 2007 Holthouse Water District had a Cost-of-Service Rate of $25.93 per acre-foot, but
since the landowners qualify for ability-to-pay relief they only had to pay $16.42 per
acre-foot.14 When the District was formed, all that was necessary were the turnouts on
the Tehama-Colusa Canal. The water is gravity-fed through ditches.15
4. MUNICIPAL SERVICE REVIEW
Colusa LAFCO is responsible for determining if an agency is reasonably capable of
providing needed resources and basic infrastructure to serve areas within its boundaries
and within the Sphere of Influence.
LAFCO evaluates the present and long-term infrastructure demands and resources
available to the District, analyzes whether resources and services are, or will be, available
at needed levels, and determines whether orderly maintenance and expansion of such
resources and services are planned to occur in line with increasing demands.
The Municipal Service Review Guidelines prepared by the Governor’s Office of
Planning and Research recommend issues relevant to the jurisdiction be addressed
through written determinations called for in the Cortese-Knox Hertzberg Act.
Written Determinations are provided for each of the five factors, based on the
information provided in this Municipal Service Review.

Holthouse Water District - Adopted March 6, 2008 6
LAFCO Resolution 2008-0004 – Municipal Service Review
LAFCO Resolution 2008-0007 – Sphere of Influence
Purpose: To evaluate service needs based on existing and anticipated growth
patterns and population projections.
4.1.1 Population Growth
There is no population within the District. The District is farmland and it is better
for residents of Colusa County to live in area where municipal services are
provided such as Maxwell.
4.1.2 MSR Determinations on Growth and Population
1-1) The population of the District is zero and is expected to remain the same.
4.2 Capacity and Infrastructure
Purpose: To evaluate the infrastructure needs and deficiencies in terms of supply,
capacity, condition of facilities and service quality.
4.2.1 Infrastructure Background
The water is from the Tehama-Colusa Canal and is inadequate for the District.
The infrastructure is limited to the turn-outs from the Canal and gravity-fed
ditches.
4.2.2 MSR Determinations Regarding Capacity and Infrastructure
2-1) The water allocated to the District is inadequate for the needs of the land
in the District because the land has been planted to almond orchard in the
past five years.
4.3 Financial Ability
Purpose: To evaluate factors that affect the financing of needed improvements and
to identify practices or opportunities that may help eliminate unnecessary costs
without decreasing service levels.
4.3.1 Financial Considerations
The District does not have a separate financial structure. The water users pay for
the water and maintenance directly.
4.3.2 MSR Determinations on Financial Ability
Holthouse Water District - Adopted March 6, 2008 7
LAFCO Resolution 2008-0004 – Municipal Service Review
LAFCO Resolution 2008-0007 – Sphere of Influence
3-1) The District may need to contract with another Water District for
management services in the future.
4.4 Opportunities for Shared Facilities
Purpose: To evaluate the opportunities for a jurisdiction to share facilities and
resources to develop more efficient service delivery systems.
4.4.1 Facilities
The District does share facilities because the Tehama-Colusa Canal provides
water for many districts.
4.4.2 MSR Determinations on Shared Facilities
4-1) The District-specific water conveyance facilities cannot be shared with
any other district.
4.5 Government Structure and Accountability
Purpose: To consider the advantages and disadvantages of various government
structures that could provide public services, to evaluate the management
capabilities of the organization, and to evaluate the accessibility and levels of public
participation associated with the agency’s decision-making and management
processes.
4.5.1 Government Structure
The contracts with the US Bureau of Reclamation secure the water rights for the
landowners. The District would not want to make any changes that could cause the loss
of water rights or insufficient water for the landowners now in the District.
The District has a three-member Board of Directors. Because there are so few land-
owners and no residents within the District, public participation is not an issue.
4.5.2 MSR Determinations on Government Structure and Accountability
4-1) The government is accountable to the US Bureau of Reclamation for
payment for water received and for various forms.
5. SPHERE OF INFLUENCE
Holthouse Water District - Adopted March 6, 2008 8
LAFCO Resolution 2008-0004 – Municipal Service Review
LAFCO Resolution 2008-0007 – Sphere of Influence
Information contained in the Municipal Service Review and this Sphere of Influence
update is only current as of the date of adoption.
LAFCO Policy 3.3(e) calls for an updated Master Services Element at the time a proposal
is made. Policy 2.14 essentially requires an updated Master Services Element any time
conversion of agricultural land meeting the definition contained in the California
Government Code §56064 is proposed.
The Sphere of Influence for the Holthouse Water District was adopted to extend one mile
from the District Boundary in all directions in 1985 and was updated in 1990 with no
change.16 Based on present conditions, this Sphere of Influence is no longer suitable for
the District and a reduced Sphere of Influence is in order.
The proposed Sphere of Influence for the Holthouse Water District will be smaller than
the District Boundary and will allow detachment of parcels so they can be annexed to the
adjacent Glenn-Colusa Irrigation District (GCID).
The Sphere of Influence for the District will be the same as the District Boundary but
will not include the following three parcels:
1. Allen Etchepare: 320.0 acres, APN 011-190-010
2. Jeanmarie Etchepare: 86.3 acres, APN 011-140-010
3. Jeanmarie Etchepare: 28.9 acres, APN 011-220-078
The 28.9 acre parcel was previously annexed into the Glenn-Colusa Irrigation District but
was never detached from the Holthouse Water District.17
The Sphere of Influence will be 1,557.8 acres and will include only land owned by the
Holthouse family.
5.1 Land Use
5.1.1 Present and Planned Land Uses in the Area, Including Agricultural and
Open Space Lands
The General Plan designation for the Holthouse Water District is AG
(Agriculture) and the zoning is EA (Exclusive Agriculture). There is a small part

of the District designated UA (Upland Agriculture) and zoned AP (Agriculture
Preserve).18 This area is not affected by the proposed detachments.
None of the parcels to be detached are included in a Williamson Act Contract.19
5.1.2 SOI Determinations Present and Planned Land Use
1-1) The land within the District is used for agriculture.
1-2) The reduced Sphere of Influence is logical because there is not enough
water to serve all the land in the District.
5.2. Municipal Services: Present Need
5.2.1 Facilities and Services: Present and Probable Need
There is a need for the water provided to irrigate the crops in the District. The
water provided is not sufficient for the entire District so a reduced Sphere of
Influence is appropriate.
5.2.2 SOI Determinations for Facilities and Services
2-1) The facilities are adequate to supply the amount of water available from
the Tehama-Colusa Canal.
5.3 Public Facilities Future Capacity
5.3.1 Facilities and Capacity
There is no way to increase the amount of water allocated to the Holthouse Water
District so there is no need to increase the water delivery facilities. Depending on
weather conditions less water may be available in dry years.
5.3.2 SOI Determinations for Public Facilities Present and Future Capacity
3-1) The amount of water available from the Tehama-Colusa Canal is limited
and variable due to the weather conditions.
5.4 Social or Economic Communities of Interest

5.4.1 Holthouse Water District
The Holthouse Water District was formed to get T-C Canal water for the
Holthouse lands. Other lands were included in the District but these lands are
adjacent to the Glenn-Colusa Irrigation District and could be better served by the
GCID.
5.4.2 SOI Determinations for Social or Economic Communities of Interest
4-1) The Holthouse Water District serves agricultural land owned by the
Holthouse family. There is no social or economic community in the
conventional sense of the phrase.

DEFINITIONS
Acre foot: The volume of water that will cover one acre to a depth of one foot, 325,850 US
gallons or 1,233,342.2 liters.
Bureau of Reclamation: (USBR, Reclamation, BOR). The mission of the Bureau of
Reclamation is to manage, develop, and protect water and related resources in an
environmentally and economically sound manner in the interest of the American public.20
Central Valley Project: The Central Valley Project (CVP), one of the nation's major water
conservation developments, extends from the Cascade Range in the north to the semi-arid but
fertile plains along the Kern River in the south. Initial features of the project were built primarily
to protect the Central Valley from crippling water shortages and menacing floods, but the CVP
also improves Sacramento River navigation, supplies domestic and industrial water, generates
electric power, conserves fish and wildlife, creates opportunities for recreation, and enhances
water quality.21
Drip irrigation: Drip irrigation, also known as trickle irrigation or micro-irrigation is an
irrigation method that minimizes the use of water and fertilizer by allowing water to drip slowly
to the roots of plants, either onto the soil surface or directly onto the root zone, through a
network of valves, pipes, tubing, and emitters. Modern drip irrigation has arguably become the
most important innovation in agriculture since the invention of the impact sprinkler in the 1930s,
which replaced wasteful flood irrigation. Drip irrigation may also use devices called micro-spray
heads, which spray water in a small area, instead of dripping emitters. These are generally used
on tree and vine crops with wider root zones.22
Exempt land: Irrigation land in a district to which the acreage limitation and pricing provisions
of Reclamation law do not apply.23
Gravity flow: Flow of water in a pipe on a descending path.
Irrigate: To supply (dry land) with water by means of ditches, pipes, or streams; water
artificially.
Irrigation system: A complete set of system components including the water source, the water
distribution network, and the general irrigation equipment.
Lateral: A pipe line other than the main water pressure line used to move water to the various
delivery devices.

must be lifted in a well from the pumping level to the ground surface.
Tehama-Colusa Canal: The Tehama-Colusa Canal is 110 miles long and serves 14 water
districts. The system was designed to divert water from the Sacramento River into the settling
basin by virtue of a dam across the Sacramento River located in Red Bluff, California.
Tehama-Colusa Canal Authority: The Tehama-Colusa Canal Authority operates and maintains
two canal systems owned by the Bureau of Reclamation, the Corning Canal and the Tehama-
Colusa Canal.24
Water transfers: Selling or exchanging water or water rights among individuals or agencies.
Artificial conveyance of water from one area to another.
