It contains excerpts from the individual Federal-State water quality standards establishing pollutant specific criteria for interstate surface waters. The water quality standards program is implemented by the U. S. Environmental Protection Agency where responsibility for providing water quality recommendations, approving State-adopted standards for interstate waters, evaluating adherence to the standards, and overseeing enforcement of standards compliance, has been mandated by Congress. Standards, a nationwide strategy for surface water quality management, contain three major elements; the use (recreation, drinking water, fish and wildlife propagation, industrial, or agricultural) to be made of the navigable water; criteria to protect these uses; and an antidegradation statement to protect existing high quality waters, from degradation by the addition of pollutants. Guidance for the development of standards by individual States is contained in two EPA documents entitled Water Quality Standards Handbook (1983) and Quality Criteria for Water (1986). Through their water quality standards, a State must establish stream use designations which will reflect the goals of the Clean Water Act. Once established, the use must be maintained by means of the criteria guidance incorporated into the standards. However, where designated uses and their specific criteria are less protective than the existing stream quality, the State must upgrade that stream to reflect the criteria levels needed. At the very least, current designated stream uses must be maintained in the State water quality standards. Less restrictive uses may be imposed on a stream only when attainment of the designated use would be impractical because of: 1) a high natural background of water constituent(s); 2) irretrievable man-induced conditions producing high levels of constituent(s); or 3) substantial and widespread adverse economic and social impact which would result from a greater degree of municipal or industrial wastewater treatment. Since water quality standards experience revisions and upgrading from time to time, the following procedures set forth in the Clean Water Act, individual entries in this digest may be superseded. As these revisions are accomplished and allowing for the States to revise their standards accordingly, this digest will be updated and reissued. Because this publication is not intended for use other than as a general information resource, to obtain the latest information and special purposes and applications, the reader needs to refer to the existing approved water quality standards. These can be obtained from the State water pollution control agencies of the EPA Regional Offices. -2- ------- REFERENCES 5 California Water Quality Standards by River Basins, ca. 1975 For more detailed information on selected basins, sub-basins and stretches of streams and coastal areas, refer to California State Water Quality Standards. 19 Maine Water Classification Program, Maine Revised Statutes Annotated, Title 38, Article 4-A, State of Maine Department of Environmental Protection, May 1987, pp. 12-17. 23 Minnesota Standards for the Protection of the Quality and Purity of the Waters of the State, Minnesota Rules Chapter 7050, 1988. 25 Missouri Water Quality Standards, 10 CSR 20-7.031, Rule of Department of Natural Resources: Division 20 - Clean Water Commission. 27 Nebraska Water Quality Standards, Title 117, Chapter 1, Nebraska Department of Envronmental Control. 33 State of North Carolina Administrative Code Section: 15 NCAC 2B .0200 - Classifications and Water Quality Standards Applicable to Surface Waters of North Carolina. 35 Ohio Water Quality Standards, Chapter 3745-1 of the Administrative Code, Ohio Environmental Protection Agency, 1985. 43 Texas Surface Water Quality Standards, Texas Water Commission, Rule Change, 1988. 44 Utah Standards of Quality for Waters of the State, Wastewater Disposal Regulations: Part II, State of Utah Department of Health: Division of Environmental Health, 1988. 45 Vermont Water Quality Standards, State of Vermont Water Resource Board, 1987. 46 Virginia Water Quality Standards, State Water Control Board, 1987. 48 Water Quality Standards, West Virginia Legislative Rules, State Water - Resources Board, 1985. 51 Water Quality Standards for American Samoa, July 1984, p. 4-12. 53 Revised Guam Water Quality Standards, Guam Environmental Protection Agency, February 24, 1984, pp. 3,6. 54 Commonwealth of the Northern Mariana Islands Marine and Fresh Water Quality Standards, Commonwealth Register, Vol. 8 No. 5, August 15, 1986, pp. 4462-4463. -3- ------- 56 Marine and Fresh Water Quality Standard Regulations, Trust Territory, March 31, 1986, pp. 3-5. 57 Environmental Laws and Regulations of the Virgin Islands, 1985.

Classifications may be established for any state surface waters, except that -13- ------- State Water Use Classification water in ditches and other manmade conveyance structures shall not be classified. (1) CLASSIFICATIONS (a) Recreation (i) Class 1 - Primary Contact These surface waters are suitable or intended to become suitable for prolonged and intimate contact with the body or for recreational activities when the ingestion of small quantities of water is likely to occur. such waters include but are not limited to those used for swimming. (ii) Class 2 - Secondary Contact These surface waters are suitable or intended to become suitable for recreational uses on or about the water which are not included in the primary contact subcategory. (b) Agriculture These waters are suitable or intended to become suitable for irrigation of crops usually grown in Colorado and which are not hazardous as drinking water for livestock. (c) Aquatic Life These surface waters presently support aquatic life uses as described below, or such uses may reasonably be expected in the future due to the suitability of present conditions, or the waters are intended to become suitable for such uses as a goal: (i) Class I - Cold Water Aquatic Life: These are waters that (1) currently are capable of sustaining a wide variety of cold water biota, including sensitive species, or (2) could sustain such biota but for correctable water quality conditions. Waters shall be considered capable of sustaining such biota where physical habitat, water flows or levels, and water quality conditions result no substantial impairment of the abundance and diversity of species. (ii) Class 1 - Warm Water Aquatic Life: These are waters that (1) currently are capable of sustaining a wide variety of warm water biota, including sensitive species, or (2) could sustain such biota but for correctable water quality conditions. Waters shall be considered capable of sustaining such biota where physical habitat, water flows or levels, -14- ------- State ffater Use Classification and water quality conditions result in no substantial impairment of the abundance and diversity of species. (iii) Class 2 - Cold and Warm Vater Aquatic Life: These are waters that are not capable of sustaining a wide variety of cold or warm water biota, including sensitive species, due to physical habitat, water flows or levels, or uncorrectable water quality conditions that result in substantial impairment of the abundance and diversity of species.

After receiving treatment (defined as coagulation, flocculation, sedimentation, filtration, and disinfection with chlorine or its equivalent) these waters will meet Colorado drinking water regulations and any revisions, amendments, or supplements thereto. (2) QUALIFIERS The following qualifiers may be appended to any classification to indicate special considerations. Where a qualifier applies, it will be appended to the use classification; for example "Class 1, Warm Water Aquatic Life (Goal)." (a) Goal A qualifier which indicates that the waters are presently not fully suitable but are intended to become fully suitable for the classified use. "Goal" will be used to indicate that a temporary modification for one or more of the underlying numeric standards has been granted. (b) Seasonal A qualifier which indicates that the water may only be suitable for a classified use during certain periods of the year. During those periods when water is in the stream, the standards as defined in 3.1.7(l)(b) and 3.1.9(1) shall apply. (c) Interrupted Flow A qualifier which indicates that due to natural or human-induced conditions the continuity of flow is broken, not necessarily according to a seasonal schedule. This qualifier appended to a classification indicates that the flow conditions still permit the classified use during periods of flow. The presence of water diversions in a stream does not change the -15- ------- State Water Use Classification classifications and standards, and the standards do not require that flow be maintained in the stream.

The following use-designations are provided: Unspecified Waters. Surface waters not specified in Idaho Department of Health and Welfare Rules and Regulations Section 01.2110 -- 01.2160 are designated as primary contact recreational waters, unless the physical characteristics of a water body prevent primary contact recreation. In those cases, the water body is designated a secondary contact recreational water. Industrial Water Supplies, Wildlife Habitats, and Aesthetics. All State waters are designated for the uses of industrial water supplies, wildlife habitat and aesthetics. Water quality standards for those uses will generally be satisfied by the general water quality standards (Idaho Department of Health and Welfare Rules and Regulations Section 01.2200). Should specificity be desirable or necessary to protect a specific use, appropriate criteria will be adopted in Idaho Department of Health and Welfare Rules and Regulations Sections 01.2250 or 01.2275 01.2299. Man-Made Waterways. Unless designated in Idaho Department of Health and Welfare Rules and Regulations Sections 01.2110 01.2160, man-made waterways are to be protected for the use for which they were developed. Private Waters. Unless designated in Idaho Department of Health and Welfare Rules and Regulations Sections 01.2110 01.2160, lakes, ponds, pools, streams and springs outside public lands but located wholly and entirely upon a person's land are not protected specifically or generally for any beneficial use. Groundwaters. Groundwaters not specified in Idaho Department of Health and Welfare Rules and Regulations Sections 01.2110 01.2160 are designated protections for potable water supplies unless the existing groundwater quality precludes the economic feasibility of use as a domestic source due to natural or man made causes as determined by the Department. In those cases, the groundwater will be protected for other existing beneficial uses, if any, as determined by the Department.

Water Use; It is the policy of the State of Louisiana that all state waters should be protected for recreational uses in and/or on the water and for the preservation and propagation of desirable species of aquatic biota such as indigenous species of fish, shellfish and wildlife. Use and value of water for public water supplies, agriculture, industry, and other purposes as well as navigation, shall also be considered in setting Standards. However, the most stringent criteria specified for each parameter shall be applicable where waters are classified for multiple uses. In applying this policy, the terms "recreational uses" and "desirable species of aquatic biota" will be given common sense application. Recreational uses will be specified as either "primary contact" or "secondary contact". "Desirable species of aquatic biota" refers to a diverse and naturally occurring range of aquatic biota and not to species that exist in the area in question in disproportionate numbers as a result of man's waste discharges. Desirable species of fish, shellfish, wildlife and other aquatic biota will be specified as "fresh warmwater," or "marine water" species. All future designations of stream uses and their associated criteria must, at a minimum, adhere to these classifications except as provided below. -26- ------- State Water Use Classification C. Exceptions! The existence of poor water quality vill be viewed as a problem to be solved, not as an impediment against assigning a use classification. However, some waters, because of naturally occurring poor quality or technological limitations, may qualify for an excepted classification. This determination, however, will be made on a case-by-case basis following the analysis of each such area. In all cases where exceptions are proposed the concurrence of the regional administrator of the EPA will first be obtained. In any case where the exception is based on technological limitations, the exception will be temporary i.e., the exception will be reviewed at least every three years as required by Section 303(c) of the Clean Water Act to determine the possibility of upgrading. Two categories for which exceptions are allowed are for certain intermittent streams and man-made watercourses. WATER USE DESIGNATIONS There are seven water use designations for surface- waters in the State of Louisiana: (A) primary contact recreation, (B) secondary contact recreation, (C) fish and wildlife propagation, (D) public water supply, (E) shellfish propagation, (F) agriculture, and (G) outstanding natural resource waters. A description of each follows. Primary contact recreation is defined as any recreational or other water use in which there is prolonged and intimate contact with the water involving considerable risk of ingesting water in quantities sufficient to pose a significant health hazard such as swimming, water skiing, skindiving, wading, and other similar activities. Secondary Contact Recreation is defined as any- recreational or other water use in which contact with the water is either incidental or accidental and in which the probability of ingesting appreciable quantities of water is minimal, such as fishing, commercial or recreational boating and any limited contact incident to shoreline activity. Fish and Wildlife Propagation includes the use of water for preservation and reproduction of aquatic biota such as indigenous species of fish and invertebrates as well as reptiles, amphibians and other wildlife associated with the aquatic environment. Public Water Supply refers to the use of water for human consumption and general household use. Shellfish Propagation is the use of water to sufficiently maintain the health of biological systems which support commercially important species of shellfish primarily oyster, and to protect the health of human consumers of these shellfish. -27- ------- State Water Use Classification Agriculture involves the use of water for crop spraying, irrigation, livestock watering, poultry operations, and other farm purposes, not related to human consumption. Outstanding Natural Resource Vaters includes areas designated for preservation, protection, reclanation or enhancement of wilderness and aesthetic qualities and ecological regimes, such as Louisiana natural and scenic streams, and waters within wildlife refuges. 19 Maine Designated uses of fresh surface waters: Class AA.

Nebraska27 It is the public policy of the State of Nebraska to conserve the water in this State and to protect and improve the quality of surface water for human consumption, wildlife, fish and other aquatic life, industry, recreation, and other productive, beneficial uses. Beneficial uses are assigned to surface waters within or bordering upon the State of Nebraska, and are protected through the restrictions imposed by the numeric and narrative criteria. Some uses require higher quality water than others. Vhen multiple uses are assigned to the same waters, all assigned uses will be protected. Beneficial uses will also be protected by permits issued in accordance with requirements of current water quality standards and through practical management or regulatory programs for non-point sources. The beneficial uses defined by these standards are: (1) Recreation Class A - Primary Contact Recreation. Primary contact recreation includes activities where the body may come into prolonged or intimate contact with the water, such that water may be accidentally ingested, it is not intended to be used as a potable water supply unless acceptable treatment is applied. These waters may be used for swimming, water skiing, canoeing, and similar activities. Class B - Secondary contact recreation. Secondary contact recreation includes activities where the body usually does not come into prolonged or intimate contact with the water. It is very unlikely that the water will be ingested nor will sensitive body organs -37- ------- State Vater Use CJassification (e.g., eyes, ears, nose, etc.) be exposed. The waters may be used for fishing, hunting, and similar activities. (2) Aquatic Life Class A - Coldvater Habitat. These waters provide, or could provide, water quality and habitat conditions (e.g. flow, substrate, cover) which support a significant salmonid (trout) population. All waters which support a naturally reproducing trout population are included. Class B - Coldwater Habitat. These are waters where coldwater aquatic life (including salmonid populations) is limited by natural water quality or habitat conditions. These waters will not support salmonid spawning, but may support a salmonid population if periodically stocked. Waters which serve as seasonal pathways for salmonid migration are included. Class A - Warmwater Habitat. These waters provide, or could provide, water quality and habitat conditions (e.g. flow, substrate, cover) which maintain a wide variety of warmwater biota. These waters will support fis'h populations of recreational importance or populations of threatened .species. Class B .- Warmwater Habitat. These are waters where the potential variety of life forms is presently limited by degraded water quality (natural or irretrievable human-induced conditions) or habitat conditions. These waters will support fish populations consisting of nonsensitive forage species. (3) Water Supply - Public Drinking Water These are surface waters which serve as a potable water supply. These waters must be treated (e.g., coagulation, sedimentation, filtration, chlorination) before the water is suitable for human consumption. After treatment, these waters are suitable for human domestic drinking water, food processing, and similar uses. (4) Agriculture Class A - Agricultural. These are waters used for general agricultural purposes (e.g., irrigation and livestock watering) without treatment. -38- ------- State gater Use Classification Class B - Agricultural. These are waters where the natural background water quality limits its use for agricultural purposes. (5) Industrial These waters are potentially suitable for commercial or industrial use as cooling or processing (nonfood) water. Water quality criteria necessary to protect this use will vary depending on the type of industrial process involved. Where actual uses are identified, site specific criteria will be developed to protect the use when necessary. (6) Aesthetics and Public Health This use applies to all surface waters of the state. To be aesthetically acceptable, waters shall be free from human induced pollution which causes: 1) noxious odors; 2) floating, suspended, colloidal, or settleable materials that produce objectionable films, colors, turbidity, or deposits; and 3) the occurrence of undesirable or nuisance aquatic life (e.g., algal blooms).

These streams all have low average flows, and generally, prolonged periods of no flow. The physical and chemical criteria shall be those for Class II, with some exceptions. 35 Ohio Vamrvater Habitat: These are waters capable of supporting reproducing populations of warmwater fish and associated vertebrate and invertebrate organisms and plants on an annual basis. Limited Varmvater Habitat: These are waters incapable of meeting specific warmwater habitat criteria necessary for the support of populations of fish and associated vertebrate and invertebrate organisms and plants either on a seasonal or year around basis due to natural conditions, irretrievable, man-induced conditions or the demonstration that meeting the criteria would cause substantial and widespread economic and social impact. Criteria for the support of this use designation will' be the same as the criteria for the support of the use designation warmwater habitat. However, individual criteria will be varied on a case-by-case basis and will supersede the criteria for warmwater habitat where applicable. Any exceptions from warmwater habitat criteria will apply only to specific criteria during specified time periods and/or flow conditions. Mine drainage streams, i.e., those streams currently degraded by mine drainage primarily resulting from inactive surface and underground mining operations and associated refuse piles, may be exempt from one or more of the following criteria: pH, total dissolved solids, iron, zinc. Allowable stream concentrations for these exempted parameters will vary depending upon the condition of the inactive mines in that area. The limited warmwater habitat use designation must be recommended in a written report approved by the director. All stream segments designated limited warmwater habitat will be reviewed on a triennial basis (or sooner) to determine whether the use designation should be changed. Exceptional Warmwater: These are waters capable of supporting exceptional or unusual populations of -48- ------- State Water Use Classification warmwater fish and associated vertebrate and invertebrate organisms and plants on an annual basis. These would include waters of exceptional chemical quality that support sensitive species of warmwater fish, exceptionally diverse aquatic communities, and/or outstanding recreational or commercial fisheries. In addition to those stream segments designated in rules 3745-1-08 to 3745-1-30 of the Administrative Code, all publicly owned lakes and reservoirs, except upground storage reservoirs, are designated exceptional warmwater habitat. Seasonal Salmorid Habitat: These are waters capable of supporting the passage of salmonids from October through May and are water bodies large enough to support recreational fishing. This use will be in effect the months of October through May. Another aquatic life habitat use designation will be enforced the remainder of the year (June through September.) Coldwater Habitat: These are waters capable of supporting populations of coldwater fish and associated vertebrate and invertebrate organisms and plants on an annual basis. These waters are not necessarily capable of supporting successful reproduction of salmonids and may be periodically stocked with these species. Nuisance Prevention: These waters include acid mine drainage s'treams where the infauna is substantially degraded and other heavily polluted stream segments where the fauna is degraded and the potential aquatic life use is not being attained due to irretrievable, man-induced conditions or the demonstration that meeting criteria for the support of a balanced aquatic community would cause substantial and widespread economic and social impact. This designation must be recommended in a written report approved by the Director. All stream segments designated Nuisance Prevention will be reviewed on a triennial basis (or sooner) to determine whether the use designation should be changed. The Nuisance Prevention criteria represent the minimum water quality to be met in all surface waters of the State, outside the mixing zone. Public Water Supply: These are waters that with conventional treatment will be suitable for human intake and meet federal regulations for drinking water. Agricultural Water Supply: These waters are suitable for irrigation and livestock watering without treatment. -49- ------- State Water Use Classification Industrial Water Supply: These are waters suitable for commercial and industrial uses, with or without treatment. Criteria for the support of the industrial water supply use designation will vary with the type of industry involved. Recreational: These use designations are in effect only during the recreation season, which is the period from May first to October fifteenth, for all streams except those designated seasonal salmonid habitat. The recreation season for streams designated seasonal salmonid habitat is June first to September thirtieth. Bathing Waters: These are waters that, during the' recreation season, are suitable for swimming where a lifeguard and/or bathhouse facilities are present, and include any additional such areas where the water quality is approved by the director. Primary Contact: These are waters that, during the recreation season, are suitable for full body contact recreation, such as, but not limited to, swimming, canoeing, and scuba diving with minimal threat to public health as a result of water quality. Secondary Contact Recreation: These are waters that, during the recreation season, are suitable for partial body contact recreation such as, but not limited to wading with minimal threat to public health as a result of water quality. Oklahoma Public and Private Water Supplies: The quality of the surface waters of the State which are designated as public and private water supplies shall be protected, maintained, and improved, when feasible, so that they can be used as sources of public and private raw water supplies. Drinking water standards dictate the quality of water that should be achieved in municipal water distribution system without reference to desirable raw water quality. Although it is possible to renovate highly polluted surface waters to these standards, the process required would be both complex and expensive. Raw water quality criteria have been developed to aid in the selection of water sources so that the water supply chosen can, by commonly proven, applied treatment processes, achieve the drinking water standards, all within reasonable economic limits. Emergency Public and Private Water Supplies: During emergencies, those waters designated Emergency Public and Private Water Supplies may be put to use. -50- ------- State Water Use Classification Each emergency vill be handled on a case-by-case basis, and be thoroughly evaluated by the appropriate State agencies and/or local health authorities. Fish and Wildlife Propagation: Unpolluted vaters support more diverse aquatic communities while only tolerant species can survive in comparatively polluted waters. In addition, waters which have diverse habitats will contain more species than waters with limited habitat variation. The impact of a given chemical or physical constituent on a biological community is not mutually exclusive of other constituents since synergistic interactions are common. Aside from the aesthetic qualities of fish and wildlife, it should be realized that the health of these communities of organisms can act as an index which reflects overall environmental welfare and potential health of neighboring human populations. Agriculture (Livestock and Irrigation): Proper water quality is essential for irrigation of crops and livestock consumption. The surface waters of the State shall be maintained so that toxicity does not inhibit continued ingestion by livestock or irrigation of crops. Excessive concentrations of minerals in irrigation water result in damage to crops and produce undesirable soil conditions. -Highly saline water should .be used with best management practices as outlined in "Diagnosis and Reclamation of Saline Soils," United States Department of Agriculture Handbook No. 60, (1958). Hydro-Electric Power Generation: This beneficial use is not generally dependent upon water quality. Industrial and Municipal Process and Cooling Water: Quality criteria for water used for process or cooling purposes vary with the type of industrial or municipal processes involved. This use will be protected by application of the criteria for other beneficial uses. Primary Body Contact Recreation: Primary Body Contact Recreation involves direct body contact with the water where a possibility of ingestion exists. In these cases, the water shall not contain chemical, physical, or biological substances in concentrations that are irritating to skin or sense organs or are toxic or cause illness upon ingestion by human beings. Secondary Body Contact Recreation: The water quality requirements for Secondary Body Contact Recreation are usually not as stringent as for -51- ------- State Water Use Classification Primary Body Contact Recreation. Secondary body contact recreational activities include boating, fishing, wading or other activities where ingestions of water is not anticipated. Waters shall be maintained to be free from human pathogens in numbers which may produce adverse health effects in humans. Navigation: This beneficial use is generally more dependent on water quantity than water quality. Aesthetics: To be aesthetically enjoyable, the surface waters of the State must be free from floating materials and suspended substances that produce objectionable color and turbidity. The waters must also be free from noxious odors and tastes, and from materials that settle to form objectionable deposits, and discharges that produce undesirable or nuisance aquatic life. For beneficial uses of specific waters, refer to Environment Reporter p. 881:1017-1056. 37 Oregon Final version not available. 38 Pennsylvania Protected Uses: AQUATIC LIFE Cold Water Fishes - Maintenance and/or propagation of fish species including the family Salmonidae and additional flora and fauna which are indigenous to a cold water habitat.

This category includes all stream segments extending from a point 500 feet upstream from the intake to a point one half (1/2) mile below the wastewater discharge point. (See Appendix C for representative list.) 6.6.d Category E4 - Industrial. This category is used to describe all stream segments with one or more industrial users. It does not include water for cooling. 7.b.l.2 Each segment extending upstream from the intake of a water supply public (Vater Use Category A), for a distance of (5) miles or to the headwater, must be protected by prohibiting the discharge of any pollutants in excess of the concentrations designated for this Water Use Category in Section 8. Provided, however, that within a zone extending one half (1/2) mile above the intake, the Chief, Division of Water Resources, Department of Natural Resources, may establish for any discharge effluent limitations for the protection of human health that require additional removal of those pollutants. ' (If a watershed is not significantly larger than either of the two (2) zones above the intake the water supply section may include the entire upstream watershed to its headwaters. Wisconsin o Fish and Aquatic Life o Recreational Use o Public Water Supply Wyoming 50 Vater Uses: The objectives of the Wyoming Water Pollution Control Program are specifically designed to maintain the best possible quality of waters commensurate with the following uses: a. Agriculture; b. Fish and Wildlife; c. Industry d. Public Water Supply; e. Recreation; f. Scenic Value. Surface Vater Classes and Uses: Of the uses listed above, protection and propagation of fish is, for most parameters, the use which requires the highest water -64- ------- State Water Use Classification quality. Therefore, Wyoming's surface water classes as defined below are based on this use. There are four classes of surface water in Wyoming: Class I. Those surface waters in which no further water quality degradation by point source discharges other than from dams will be allowed. In designating Class I waters, the Environmental Quality Council shall consider water quality, aesthetic, scenic, recreational, ecological, agricultural, botanical, zoological, municipal, industrial, historical, geological, cultural, archaeological, fish and wildlife, the presence of significant quantities of developable water and other values of present and future benefit to other people. Class II. Those surface waters, other than those classified as Class I, which are determined by the Wyoming Game and Fish Department to be presently supporting game fish or have the hydrologic and natural water quality potential to support game fish. Class III. Those surface waters, other than those classified as Class I, which are determined by the Wyoming Game and Fish Department to be presently supporting non-game fish or have the hydrologic and natural water quality potential to support non-gamefish. Class IV. Those surface waters, other than those classified as Class I, which are determined by the Wyoming Game and Fish Department not to have the hydrologic or natural water quality potential to support fish. In addition to the above basic classes, all Class I, II, and III waters shall receive sub-designation by the Wyoming Game and Fish Department as either "cold water" or "warm water" fisheries.
