PREFACE
The information contained heroin, has been condensed from (a) 32
\
separate policies (1) (standards) adopted by California's nine Regional Water
Duality Control Boards, and approved by the Secretary of the Interior,
(b) a Statewide Policy for the Control of Hater Duality'adopted by the State
Hater Duality Control Board (now the State Hater Resources Control Board)
and contained in a document of Associated material submitted to the Secretary
of the Interior on June 23, 19G7, and (c) supplemental submittal of standards
changes.
The State Board adopted Statewide policies, (Resolutions 67-36 through

67-41), which are applicable to each of the 32 -standards adopted by the
Regional Boards.
A summarization of this type, of necessity, omits many pertinent details.
The complete standards should be referred to for more detailed information.
The equivalence in Federal and State terminology is as follows:

SUMMARY OF WATER QUALITY STANDARDS
FOR
INTERSTATE AND COASTAL WATERS OF CALIFORNIA
Introduction
In the Water Quality Act of 1965, Congress authorized the establish-
ment of water quality standards for interstate (including coastal) waters.
The purpose of these standards is to protect and enhance the quality and
productivity of the Nation's interstate waters to serve a variety of beneficial
uses, such as public v/ater supply, recreation and protection of aquatic life,
and industrial and agricultural uses. This publication summarizes the standards
for the general information of the American public and Federal, State and
local officials as to the uses and associated requirements for interstate
waterways.
The Act, which amended the Federal Water Pollution Control Act, provided
for the States to have the first opportunity to establish standards for their
interstate waters, which were then subject to review and approval by the
Secretary of the Interior. All of the States, the District of Columbia and.
the Territories of Guam, Puerto Rico and the Virgin Islands participated in
this landmark effort to set standards.
In the course of establishing the standards, public hearings were held
by the States and other jurisdictions noted above to give the public an
opportunity to "participate in setting water quality objectives and standards.
California adopted standards (1) for its significant interstate waters
by June 14, 1%7, which were then submitted to the Department of the Interior.

Subsequently, certain revisions were made by the State in the original
standards including adoption of a policy to protect high quality waters,
and the Secretary of the Interior approved the standards, as revised, on
January 9, 1969, with the following exceptions and conditions.
Excepted From Approval
H |A I p
1... Water Quality Control Policy for harbors, marinas, and tidal prisms
of Los Angeles and Ventura Counties,
2. Water quality objectives for temperatures in all policies otherwise
approved,
3. The minimum dissolved oxygen-limit of 4.5 mg/1 for the nearshore
waters of the Santa Ana Region,
-/he
Additional Actions Recommended by Secretary of the Interior
1. Additional actions were recommended to further upgrade salinity standard
for the Sacramento - San Joaquin Delta area.
2. Development of a detailed implementation plan for improved waste
treatment and control of waste in the San Francisco Bay Area.
3. A revision of the State's waste treatment policies to conform to
the State's adopted non-degradation policy with review and modification of
waste discharge requirements where appropriate.
4.' The establishment of numerical bacteriological objectives for the
Smith, Klamath, and Colorado Rivers, Lake Topaz, and the interstate streams
of the Lahontan Region.
5. The establishnient of bacteriological objectives to protect sport
fishing, boating, and other secondary contact recreational uses in certain
tidal waters.
-------
6, The development of standards for the Lost River and niinor interstate
streams of the Lahonton 'Region.
7. Tfie upgrading of standards for the New and Alamo Rivers when Mexico
has corrected the discharge of untreated wastes into Hew River by the
-tour of Hexical i.
The items excepted for approval and those for which additional action
was recommended are currently being studied by S'tatejand various State Agencies
and by Federal water pollution control officials, and being subjected to
public hearings and action by Regional water quality boards, with a view
toward revisions of the State-adopted standards which will more adequately
meet the intent of the Federal Act t>y June 1970,
The approved standards are thus both State and Federal standards,
enforceable under the State water pollution control statutes and the Federal
Water Pollution Control Act, as amended (Section 10). The waters for which
standards were adopted are shown on the map in Figure 1.
The standards consist of three major components: designation of the
uses which interstate waters are to serve, specification of narrative and
numerical criteria to protect and enhance water quality, and specification
of a plan of implementation and enforcement, which includes^treatment and
control requirements for municipal, industrial and other waste*discharged
to or affecting interstate waters. These components are discussed in the
following sections;.all three are essential to a complete standards program.
The standards are now being implemented. However, there will be continuing
research on water quality requirements for various beneficial uses and improved
-------
WATER USES,

-------
collection and evaluation of water quality data. As more information becomes
available and experience with implementing the standards is gained, the
standards will be refined and improved to reflect this new knowledge.
Should more detailed information be required on any aspect of the
standards, it may be obtained from the State Water Resources Control Board,
State of California, in Sacramento, California, or the Federal Water Pollution
Control Administration Regional Office in San Francisco, California.
California has also established water quality standards for many of its
intrastate waters, and information on these standards may also be obtained'
from the State Water Resources Control Board. The addresses of these offices
are given on page Ho
Water Uses
The State of California designates the following uses to be protected
in various interstate waters:
Municipal and Domestic Water Supply
Agricultural Water Supply:
Li v os toe I; Watering
Irrigation
Industrial Water Supply:
Power Generation
Processing
Boiler Water
Rinsing
Cooling
Natural Resources:
' Propagation, Sustenance and Harvest of Fish and Aquatic Life
Wildlife (including shore birds)
-------
Primary Water Contact Recreation Uses:
Swimming or wading
Water Skiing
Surfing
Skin Diving
Military Exercit's
General Water-Oriented Recreation (Other than Primary-Contact);
Sport Fishing (from boats, bank, stream or surf)
Sport Boating, cruising or sailing
Tidepool and marine life study
Beachcombing and hi king
Beach recreation
Shellfish gathering
Sun bathing
Picnicing
Camping
Hunting
Esthetic and Scenic Enjoypent
Scientific, Research, and Educational Uses
Commercial Shellfish Propagation fi Harvesting
Commercial Fishing and Baltfishing
Fish Unloading and Processing
Karinas and Snail Boat Harbors
Navigation
The general aim in designating uses for particular interstate waters
pa3"6
is to recognize present CiSeft- and practicable future uses, to provide where
possible for a variety of uses, and to assure compatibility of standards
with Federal5 State and local resource planning. In order to satisfy the
intent of the Federal Water Pollution Control Act to enhance water quality,
the standards specifically provide that no interstate waters may be used
solely or primarily for waste assimilation.
-------
All interstate waters must he aesthetically pleasing, and this quality
is usually protected by narrative criteria preventing unsightly or ob-
noxious conditions, such as floating debris, oil slicks, unpleasant odors,
and colors.
Specific use designations for all interstate waters covered by the
standards are provided in Table 1.

Water Quality Criteria
The protection of water quality and uses requires the establishment;
of numerical and narrative limits on pollutants which damage these uses.
The water quality criteria in this section reflect the best scientific judgement
available as to the water quality requirements for the assigned uses.
Numerical criteria are used wherever it is reasonable to do so. However,
n
Narrative criteria are also necessary in some cases, particularly with respect
to aesthetic considerations.
Some interstate waters have a higher quality than the minimum levels
assigned for protection of water uses, and the standards seek to protect
this higher quality as much as possible in the face of increasing social
and economic development. Scientific knowledge about the exact water quality
requirements for uses is limited, and by preventing degradation of high
quality waters, the standards seek to assure optimum, not marginal, conditions
to protect the uses associated with clean waters.
Table 1 shows the water quality criteria for each use protected by the
California standards. In addition, the standards contain general narrative
criteria, including a statement on controlling degradation of high quality
waters, which are described. The standards provide for the protection of
many small ephemeral interstate streams which are not now covered by specific
use designations and criteria. The activities of man fh"ave_ now, little, if any,
impact on the natural quality of waters in these latter streams and the
State has declared a policy to maintain their present high qual i ty and -the c
establish specific use designations and criteria as the need arises.

Implementation Plan
The "action" plan of the standards is the plan of imn'temulation and
enforcement. This plan sets forth the requirements for treatment and/or
control of significant municipal and industrial waste discharges in the
State which affect interstate waters, specifies the time within which
this is to he accomplished, and contains programs for dealing with other
water pollution control problems.
The California State Water Resources Control Board was established by
the 1967 Legislature (Stats. 1967, Chap, 284}. The Board succeeded
to the functions of the former State Water Rights Board and the State
Water Quality Control Board, which were abolished. Water Pollution and
water quality are now taken into account in conjunction with availability of
unappropriated water whenever applications for appropriation of water are
considered.
The State is divided into nine regionss each with a regional board
composed of nine members appointed by the Governor for terms of four years.
The boards are authorized to adopt regional water quality control plans,
prescribe waste discharge requirements, and perform other functions concerning
water quality control matters in their respective regions, subject to
State Board review or approval. There are dissimilanties among the nine
regional organizations. The principal reasons for the differences are:
1) the particular problems of a region; 2) the preference of the board
for a particular organizational structure; and 3) the size of the regional
board's staff. However, since the rasponsibilities of the regional boards
are the same, their methods of accomplishing program goals are similar.
-------
In general, the standards of California call for the best practicable
treatment for all discharges. State statutes prohibit specifying type
or degree of treatment or minimum treatment that must be provided.
Control is obtained through establishing waste discharge or receiving
water requirements.- On a case-by-case basis the effect of each discharge
on the quality and beneficial uses of the particular receiving water is
reviewed by the Regional Hater Quality Board in which the receiving water
is located. This board then establishes either, or both,, the discharge
or receiving water requirement. It is the responsibility of the discharger
to provide the treatment or control to meet the specified requirement.
The foregoing described procedure has resulted in the prohibiting of all
discharges to many streams and confined bodies of water, to the export of
all effluent out of a basin, to determinations that even tertiary treatment
is inadequate, or to less restrictive treatment measures coupled with special
discharge facilities or locations.
The State policy is to pay particular attention to confined or simi-
confined bodies of water and to review all discharge requirements periodically
to upgrade these with changing uses or water quality conditions. All
discharges for which requirements have been established are to be in
compliance by 1972. However, the majority have mandatory compliance
dates of 1970. Information on the requirements of any particular discharger
may be obtained from the State Water Resources Control Board, Sacramento,
California,

GLOSSARY Or "TERMS
Ambient Receiving Hater Temperature - The existing temperature of
the receiving water as determined by measurements at locations,
depths» and times which represent conditions unaffected by the
elevated temperature waste discharge under consideration.
Bacteria - For many years the best indicator of the sanitary quality
of water has been an estimate of the density of coliform bacteria.
More recently, tests have been developed for the determination of
fecal coliform and fecal streptococci, which give a better indication
of the concentration of bacteria.in waters which may be harmful
to human health. Bacterial concentrations originate primarily from
municipal waste treatment plants, sanitary sewers, storm drains,
vessels and agricultural wastes.
Beneficial uses - Of the waters of the state that may be protected
against quality degradation include, but are not necessarily limited
to, domestic, municipal, agricultural and industrial supply, power
generation; recreation; esthetic enjoyment; navigation; and prevservation
and enhancement of fish, wildlife, and other aquatic resources or
preserves.
Biochemical Oxygen Demand (BOD) - The quantity of oxygen utilized in
the biochemical oxidation of organic matter in a specified time
and at a specified temperature. Waste discharges containing high
levels of BOO will deplete oxygen supplies in receiving waters.
/J-
-------
Coastal Haters - Waters of the Pacific Ocean other than enclosed bays
and estuaries which are within the territorial limits of California*
Contamination - Means an impairment of the quality of the waters of the
state by waste to a degree which creates a hazard to the public
health through poisoning or through the spread of disease. "Con-
tamination" shall include any equivalent effect resulting from the
disposal of waste, whether or not waters of the state are affected.
Disinfection - The killing of the larger portion (but not. necessarily
all) of the harmful and objectionable microorganisms in, or on,
a medium by means of chemicals, heat, ultraviolet light, etc.
Chiorination is the method commonly employed in sewage treatment
processes.
Dissolved Oxygen (P.O.) - The oxygen dissolved as a gas in sewage,
water or other liquid usually expressed in milligrams per liter (rng/1),
parts per million or percent saturation. Adequate dissolved
oxygen levels are necessary in waters to protect fish and other
aquatic life and to precent offensive odors. Low dissolved oxygen
concernat'ions are generally due to excessive organic solids discharged
as a result of inadequately treated waste (having high BOD), „
excessive algal growths may cause vastly fluctuating dissolved oxygen
levels^,- and other factors such as temperature and water movement
have an impact on dissolved oxygen levels.
Enclosed 'Bays - Indentions along the coast which enclose an area of
oceanic water within distinct headlands or harbor works. Enclosed
bays will include all bays where the narrowest distance between
headlands or outermost harbor works is less than 75 percent of the
/J
-------
greatest dimension of the enclosed portion of the bay. This definition
includes but is not limited to the following: Humboldt Bay, Bodega
Harbor, Tomales Bay, Drakes Estero, San Francisco Bay, Carmel Bay,
Morro Bay, Los Angeles Harbor, San Diego Bay.
10. Estuaries and Coastal Lagoons - Waters at the mouths of streams
which serve as mixing zones for fresh and ocean water. Estuarine
waters will generally be considered to extend from a bay or the open
ocean to the upstream limit of tidal action but may be considered
to extend seaward if significant mixing of fresh and saltwater occurs
in the open coastal waters. This definition includes but is not
limited to the following: Smith River, Klamath River, Mad River,
Eel River, Noyo River, Russian River, Sacramento River Downstream
to Carquinez Bridge, Sacramento-San Joaquin Delta as defined by Section
12220 of the California Water Code.
Interstate Waters - Under the Federal Water Pollution Control
Act, interstate waters are defined as:
ft
a. -rivers, lakes and other waters which flow across or form
a part of State or international boundaries;
b. "waters of the Great Lakes;
C
c. coastal waters—whose scope has been defined to include
ocean waters seaward to the territorial limits and waters
along the coastline (including inland streams) that are
'influenced by the rise and fall of the tide.
-------
I [
12. pH - The index of hydrogen ion activity, used as an indication of
acid or alkalinity in water. The pH of most waters ranges
from 6.5 to 8.5. and most uses of water such as aquatic life
propagation, prosper at these levels. In most cases, a pH
outside this range is due to discharge of industrial wastes or
decaying organic vegetation,
13. Pollution - The addition of sewage, industrial wastes or other
harmful or objectionable material to water at a concentration
or in sufficient quantity to result in measurable degradation
of water quality.
14. Primary and Secondary Contact Recreation - Also called Whole-
body Contact Recreation, Primary Contact Recreation includes
uses of water such as swimming, water skiing and skin diving.
Secondary Contact Recreation, also called Partial-body Contact
Recreation, includes such recreational uses as boating and fishing.
15. Primary Treatment - Hay be defined as that process or group of processes
capable of removing a high percentage of floating and settleable
solids. This is the first major treatment in a set/age treatment
works, and generally removes from 30 to 65 percent of the suspended
soldis and 30 to 40 percent of the 5-day biochemical oxygen demand.
16. Regional Board - Means any California Regional Water Quality
Control Board for a region as specified in Section 13200
(Porter-Cologne Water Quality Control Act).
/./
-------
17. Secondary Treatment - May be defined as that process or group
of processes capable of removing virtually all floating and
settleable solids, generally from 80 to S5 percent of the 5-day
biochemical oxygen demand, and a similar level of removal of
suspended solids in untreated waste. The equivalent treatment
may generally be defined as that process or group of processes
achieving maximum practicable removal of solids, oils, grease,
acids, alkalis, toxic materialsv bacteria, taste and odor
causing materials, color and any other objectionable constituents
contained in untreated waste to produce an effluent equivalent
to that obtained from secondary treatment of sewage or the
effluent from the most efficient treatment facilities in current
use for any specific category of industrial waste,
18. Sewage - (1) The water supply of a community after it has been
used and discharged into a sewer, (?) wastewater from the sanitary
conveniences of dwellings, business buildings, factories
and other institutions.
19. Sewage, Combined - A sewage containing both sanitary sewage and
surface or storm water with or without industrial wastes.
20. Sewer, Combined - A sewer which carries both sanitary sewage
and storm drainage. At times of heavy rainfall, the capacity
of combined sewers may be exceeded and sewers will overflow. The
overflow will bypass the sewage treatment plant and the combined
wastewaters will be discharged directly into streams without
treatment of any kind. This is a problem in many older cities in
the United States, and there are various programs to deal with
it.
//
/ b
-------
21. Solids, Settlcable - Suspended solids which will subside in
quiescent water, sewage or other liquid in a reasonable period.
22. Solids, suspended - Solids that either float on the surface of,
or are in suspension in, water, sewage or other liquids and which
are largely removable by laboratory filtering.
23. State Board - Means the State Water Resources Control Board.
24. Temperature - Extreme temperatures primarily affect the aquatic
life use of waters. While temperature is affected by natural
conditions, man has a significant effect by the construction
and operation of dams and the discharge of cooling waters from
industrial processes, particularly power.
25. Toxic Materials - These may include hundreds of compounds
present in waters due to industrial wastes, runoff from farm
lands where pesticides have been applied and other causes which
are harmful to human, plant,' animal and aquatic life.
26• Quality of the water or quality of the waters - Refers to
chemical, physical, biological, bacteriological, radiological,
and other properties and characteristics of water which affect
its use,
27. Hater quality objectives - Means the limits or levels of water
quality constituents or characteristics which are established
for the reasonable protection of beneficial uses of water or .
the prevention of nuisance within a specific area.
28. Water quality control - Means the regulation of any activity
or factor which may affect the quality of the waters of the
state and includes the prevention and correction of water pollution
and nuisance.
n
-------
29. Water quality control plan ~ Consists of a designation or
establishment for the waters within a specified area of (1)
beneficial uses to be protected, (2) water quality objectives, and
(3) a program of implementation needed for achieving water quality
objectives.
30. Warm- and Cold-water Fish - Warm-water fish include black bass,
sunfish, catfish, gar and others; cold-water fish include salmon
and trout, whitefish, miller's thumb and blackfish. The temperature
factor determining distribution is set by adaptation of the eggs
to warm or cold water.

Line. Normally about two-thirds of Goose Lake is in the northeastern
part of Modoc County, California, with the remaining portion in
the south-central portion of Lake County, Oregon. At its overflow
elevation of 4,716 feet above mean sea level, surface area of the
lake is 194 square miles and the lake is 29 miles long in a north-
south direction, with a maximum width of 10 miles. The lake is
shallow with gradually sloping shorelines and it has a maximum
depth of approximately 24 feet and a capacity of over 2,250,000
acre-feet at the overflow elevation. The lake occupies the southerly
end of a semi-enclosed basin which is almost 1,100 square miles

in size, with about two--thirds of the area in Oregon, Occasional
overflow from Goose Lake is discharged from the southern end of
the basin into the North Fork of the Pit-River by way of Russell
Slough, Almost one-third (97 square miles) of the California
portion of Goose Lake Basin is mountainous, another one-third
(120 square miles) is covered by water when the lake is at its
highest elevation, while the final one-third (98 square miles)
is composed of valley and mesa lands.

Central Valley Region 5
A• Bacterialogical
1. Sacramento - San Joaquin Delta: Bacteriological quality of Delta
waters shall not exceed a median of 200 fecal coliform per 100 ml,
2. Goose Lake: "The bacteriological quality of the lake shall not
exceed a median of 1,000 coliform per 100 ml when associated with sewage
wastes as determined by the most probable number technique."
This objective provides for the health and safety of the public
who may come into contact with Goose take waters. Since coliform are
contributed by the great numbers of wildfowl abounding on the lake at
times, it is necessary to specify that the count be associated with
sewage wastes.
B. Dissolved oxygen
1. Sacramento - San Joaquin Delta: Dissolved oxygen shall not fall
below 5.0 tug/1 with the following exceptions - 1) In the water bodies
where the reduction occurs as a result of natural causes. 2) In certain
bodies of water which are constructed for special purposes and from
which fish have been excluded or the fishery is not important as a
beneficial use.
2. Goose Lake: The dissolved oxygen content shall be above 7.0 mg/1
at all times.
C. Hydrogen Ion Concentration as pH
1. Sacramento - San Joaquin Delta: 6.5 - 8.5
2. Goose Lake: 7.5 - 9.5
-------
Total Dissolved Solids
1. Sacramento - San Joaquin Delta: Total dissolved solids (TDS)
concentration of Delta waters shall.be maintained below these limits;
a. Old River at Clifton Court Ferry;
b. Cache Slough at City of Vailejo intake: 250 mg/1
c. Rock Slough at Contra Costa Canal intake;
750 mg/1, mean tidal cycle value, and
380 mg/1, mean tidal cycle value, for at least 65% of any year.
d. San Joaquin River near Vernal is; 500 mg/1 mean average concentrati
over any consecutive 30-day period.
e. Eastern Delta Channels; 700 mg/1 mean monthly concentration.
2. Goose Lake: The quantity of total dissolved solids in the lake
shall not exceed 1,300,000 tons.
The total dissolved solids concentration in Goose Lake is inversely
proportional to the volume of water in the lake so the quantity of salts
in the water has remained practically constant at about 1 million tons
during the period 1953 to 1966. The lake volume during this same period,
fluctuated from 15 to 48 per cent of total capacity. For this reason the
quantity of total dissolved solids is the best criterion for limiting the
salts in the lake.
Salt concentrations are currently limiting as regards agricultural
and fisheries use. Further, Goose Lake appears to contribute underground

flow to the Pit River Basin, arid may, under ultimate basin development,
contribute recharge waters to adjacent ground waters. This objective
seeks to prevent further build-up of salts in Goose Lake, such that
fisheries, recreational, and agricultural uses can be optimized within
the limits of salts that are naturally present.
[I. Nutrients - Plankton growth - total nitrogen
1. Sacramento - San Joaquin Delta: Materials stimulating algal growth
shall not be present in concentrations sufficient to cause objectionable
algal densities. Total nitrogen content of Delta waters shall not
exceed:
a. 1.0 mg/1 in the Central Delta
b. 2.0 mg/1 in the Western Delta.
c. 3.0 mg/1 in the Eastern Delta.
2. Goose Lake: The total plankton population shall be maintained
below bloom level. This objective is designed to protect fishlife and
recreational use of the lake by limiting the concentration of plankton
below the bloom level which is defined as that plankton concentration
which causes significant nuisance conditions, or significantly affects
desirable fish populations.
F. Biocides - toxic pfa'terials
1. Sacramento - San Joaquin Delta: Biocide content of Delta waters
shall not exceed 0.6 ug/1 as determined by the summation of individual
concentrations; nor shall concentrations of individual or combinations
of biocide reach that level found to be detrimental to fish and wildlife.
Toxic materials shall not be present in quantities sufficient to be
harmful to human, plant, animal or aquatic life.
-------
2. Goose Lake: The total chlorinated hydrocarbon pesticide content
shall not exceed 0,10 micrograms per liter as determined by the summation
of the individual concentrations, and the individual pesticide content
shall not reach those levels found to be detrimental to aquatic life
and wildlife.
Due to pesticide concentration through the food chain, the present
concentration of pesticides in rainbow trout is estimated to be 3.0
mg/1. The maximum allowable concentration of pesticides in commercially
sold fish is 7.0 rng/1, therefore any increase in the concentration of
pesticides in Goose Lake may render the fisheries resource of the lake
unusuable. In addition, small amounts of pesticides impair propagation
of aquatic life. Concentrations of 3 ppm of pesticides in roe are
reported to cause non-hatchability.
Toxic materials shall not be present in quantities sufficient to
be harmful to human, plant, animal or aquatic life,
G. Floating solids, foam and debris; oil and grease; bottom'.deposits;
tlirbi di ty
1. Sacramento - San Joaquin Delta; Goose Lake;
a. Floating solids, foam and debris, in objectionable quantities
from other than natural causes, shall be absent from Delta waters.

Goose Lake shall be free of foam, floating solids and debris from
other.than natural sources.
b. Floating or emulsified grease and oil shall not be present in
Delta waters in objectionable quantities.
Goose Lake shall be free from visible floating grease and oil

-------
c. Bottom deposits, of other than natural causes shall be absent
from Delta waters.
Goose Lake shall be free from bottom deposits of other than
natural origin.
d. Apparent color of Delta waters shall not be visibly altered
from its natural appearance. Turbidity, except for periods of
storm run-off, shall not exceed:
50 V1TU in the waters of the Central Delta
150 JTU in other Delta waters.
Mo turbidity or color of other than natural origin that will cause
visible contrast with the natural appearance of the water will be
allowed. (Goose Lake)
Tastes and Odors
1. Sacramento - San Joaquin Delta: Taste and odor producing substances
shall not be present in concentrations that will impair public water
supplies, or in such concentrations as to cause tainting of the flesh
of fish or wildfowl. Odors, other than of natural causes, shall be
absent from Delta waters.
2. Goose Lake: The lake shall not contain substances of such nature
or in such concentrations as to produce tastes or odors in fish, wildlife,
or agricultural stock. There shall be no obnoxious odor of other than
natural origin.

These values are currently ;,iat in the lake, and are generally considered
suitable for the maintenance of fish and aquatic life.
Boron
1. Goose Lake: The quantity of boron in the lake shall not exceed
4,000 tons. The concentration of boron in Goose take varies inversely
with the water surface elevation of the lake and has ranged from 2.1
to 4.8 rng/1 depending on the volume of water in the lake. The maximum
total quantity of boron has been calculated to be almost 4.00 tons
and is estimated to remain fairyly constant below this level. The purpose
of this requirement, requested by the Department of Water Resources,
is to limit the amount of boron in the lake-,;'within existing levels>; in
order to provide all possible protection for agricultural uses of waters
affected by surface or sub-surface outflows from the lake.
Fluoride
1. Goose Lake: The fluoride content of the lake shall not exceed
1,000 tons. The purpose of this objective, requested by the Department
of Water Resources, is to limit the amount of fluoride in the lake within
exisiting levels in order to provide all possible protection for domestic
uses of waters affected by surface or sub-surface outflow from the lake.
A maximum fluoride quantity of 1,000 tons will limit fluoride concentrations
in the lake to existing levels.
Radioactive Materials
1. Sacramento - San Joaquin Delta: Levels of radioactivity in water
shal 1 be in accordance with the provisions of Chapter 5, Title 17,
of the California Administrative Coda or such modifications as may be
made from time to time.
-------
?.. Goose Lake: The quantity of radioactive contaminants shall not
exceed a gross beta activity level of 1,000 picocuries per liter, an
alpha emitter level of 3 picocuries per liter and a Strontiurn-90
activity level of 10 picocuries per liter.
N. Temperature
1. Sacramento - San Joaquin Delta .-.'Temperature of Delta water shall
not be altered to a degree that adversely affects water uses.
2. Goose Lake: The mean daily temperature shall not exceed 70°F,
or the mean daily ambient air temperature, whichever is greater.
Trout, present in the lake in limited numbers, are adversely affected
by elevated lake temperatures. Daily average temperature for the main
body of tha lake water appear to range from 39 to 67°F. The Department
of Fish and Game has recommended that 70°F, which appears to be reasonably
attainable under natural circumstances, is the maximum that can be
tolerated by the existing trout fishery. Unusually warm weather may
create exceptions to this limit, and thus such possibility is recognized
by permitting higher temperatures when caused by ambient air temperature*

San Diego - Region 9
The water objectives described herein apply to the San Diego
Regional waters. For purposes of these policies, San Diego Regional
waters include:
1. Pacific Ocean within the San Diego Water Quality Control Region
applies to the waters of the Pacific Ocean along the California
coastline, between the United States -¦ Mexico boundary on the south
and the divide between Muddy and Horo Canyons on the north.
Distance from shore of the seaward limit of the area varies from
¦three nautical miles at the International boundary to a maximum
of approximately 53 nautical miles west of the City of San Diego.
2. Tijuana River Basin in California. The Tijuana River is an
ephemeral of United States and Mexico and emptying into the
Pacific Ocean approximately one and one-half miles North of the
• United States-Mexico boundary. For the purposes of applying water
quality objectives to the Tijuana River Basin in California,
hydrologic subareas are grouped into three drainages; (a) Camps
Creek, (b) Cottonwood and Tecata Creeks, and (c) the Tijuana River.
3. San Diego Bay. For ease of reference, the bay has been divided
into three sections -- South Bay, Central Bay and North Bay. South
Bay consists of the area of the bay south of the reserve fleet;
Central Bay contains that portion from South Bay to the ferry
crossing; North Bay includes the remainder of the bay from the ferry
crossing to the channel entrance.
