The information was prepared by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely sensed and other information. This data set consists of georeferenced digital map data and computerized attribute data. The map data are in a soil survey area extent format and include a detailed, field verified inventory of soils and miscellaneous areas that normally occur in a repeatable pattern on the landscape and that can be cartographically shown at the scale mapped. A special soil features layer (point and line features) is optional. This layer displays the location of features too small to delineate at the mapping scale, but they are large enough and contrasting enough to significantly influence use and management. The soil map units are linked to attributes in the National Soil Information System relational database, which gives the proportionate extent of the component soils and their properties. SSURGO depicts information about the kinds and distribution of soils on the landscape. The soil map and data used in the SSURGO product were prepared by soil scientists as part of the National Cooperative Soil Survey. Digital versions of hydrography, cultural features, and other associated layers that are not part of the SSURGO data set may be available from the primary organization listed in the Point of Contact. 2010 publication date Complete None planned -122.165247 -120.965452 42.807621 41.990281 None soil survey soils Soil Survey Geographic SSURGO Klamath Basin Restoration Agreement inlandWaters depth to water USGS Geographic Names Information System (GNIS) Oregon Klamath County Agency Lake Quadrangle (s4212125) Altamont Quadrangle (s4212151) Applegate Butte Quadrangle (s4212119) Aspen Lake Quadrangle (s4212248) Beatty Quadrangle (s4212138) Bly Quadrangle (s4212140) Bonanza Quadrangle (s4212153) Bryant Mountain Quadrangle (s4212162) Buttes of the Gods Quadrangle (s4212128) Campbell Reservoir Quadrangle (s4212033) Carr Butte Quadrangle (s4112107) Chiloquin Quadrangle (s4212126) Cooks Mountain Quadrangle (s4212129) Crystal Spring Quadrangle (s4212232) Dairy Quadrangle (s4212152) Ferguson Mountain Quadrangle (s4212139) Fort Klamath Quadrangle (s4212117) Goodlow Mountain Quadrangle (s4212155) Hamaker Mountain Quadrangle (s4212157) Hatfield Quadrangle (s4112104) Horsefly Mountain Quadrangle (s4212148) Howard Bay Quadrangle (s4212141) Keno Quadrangle (s4212149) Klamath Falls Quadrangle (s4212150) Lake of the Woods North Quadrangle (s4212239) Langell Valley Quadrangle (s4212163) Lorella Quadrangle (s4212154) Lost River Quadrangle (s4212159) Lower Klamath Lake Quadrangle (s4112103) Maklaks Crater Quadrangle (s4212216) Malin Quadrangle (s4212161) Mares Egg Spring Quadrangle (s4212224) Merrill Quadrangle (s4212160) Modoc Point Quadrangle (s4212134) Newell Quadrangle (s4112106) Paradise Mountain Quadrangle (s4212041) Pelican Bay Quadrangle (s4212240) Ponina Butte Quadrangle (s4212131) Rodeo Butte Quadrangle (s4212132) S'Ocholis Canyon Quadrangle (s4212127) Shoalwater Bay Quadrangle (s4212133) Soloman Butte Quadrangle (s4212118) Spodue Mountain Quadrangle (s4212130) Sprague River East Quadrangle (s4212137) Sprague River West Quadrangle (s4212136) Sun Pass Quadrangle (s4212109) Swan Lake Quadrangle (s4212144) Swan Lake Point Quadrangle (s4212135) Tulelake Quadrangle (s4112105) Whiteline Reservoir Quadrangle (s4212143) Wocus Quadrangle (s4212142) Worden Quadrangle (s4212158) Yainax Butte Quadrangle (s4212146) Yonna Quadrangle (s4212145) None The U.S. Department of Agriculture, Natural Resources Conservation Service, should be acknowledged as the data source in products derived from these data.

Selected attributes that cannot be visually verified on plots or on screen are interactively queried and verified on screen. In addition, the attributes are tested against a master set of valid attributes. All attribute data conform to the attribute codes in the signed classification and correlation document and amendment(s). Certain node/geometry and topology GT- polygon/chain relationships are collected or generated to satisfy topological requirements (the GT-polygon corresponds to the soil delineation). Some of these requirements include: chains must begin and end at nodes, chains must connect to each other at nodes, chains do not extend through nodes, left and right GT-polygons are defined for each chain element and are consistent throughout, and the chains representing the limits of the file are free of gaps. The tests of logical consistency are performed using vendor software. All internal polygons are tested for closure with vendor software and are checked on hard copy plots. All data are checked for common soil lines (i.e., adjacent polygons with the same label). Edge locations generally do not deviate from centerline to centerline by more than 0.01 inch. The soil survey of Klamath County, Oregon, Southern Part, is joined to the surveys of Crater Lake National Park, Oregon; Jackson County area, Oregon, Parts of Jackson and Klamath Counties; Butte Valley-Tule Lake Area, California, Parts of Siskiyou and Modoc Counties; and Modoc National Forest Area, California. An acceptable join has been obtained. A map unit is a collection of areas defined and named in terms of their soil components or miscellaneous areas or both. Each map unit differs in some respect from all others in a survey area and each map unit has a symbol that uniquely identifies the map unit on a soil map. Each individual area, point, or line so identified on the map is a delineation. Soil Scientists identify small areas of soils or miscellaneous areas that have properties and behavior significantly different than the named soils in the surrounding map unit. These minor components may be indicated as special features. If they have a minimal effect on use and management, or could not be precisely located, they may not be indicated on the map. A map unit has specified kinds of soils or miscellaneous areas (map unit components), each with a designated range in proportionate extent. Map units include one or more kinds of soil or miscellaneous area. Miscellaneous areas are areas that have little or no recognizable soil. Specific National Cooperative Soil Survey standards and procedures were used in the classification of soils, design and name of map units, and location of special soil features. These standards are outlined in Agricultural Handbook 18, Soil Survey Manual, 1993, USDA, NRCS; Agricultural Handbook 436, Soil Taxonomy, 1995, USDA, NRCS; and all Amendments; Keys to Soil Taxonomy, (current issue) USDA, NRCS; National Soil Survey Handbook, title 430-VI,(current issue) USDA, NRCS. The actual composition and interpretive purity of the map unit delineations were based on data collected by scientists during the course of preparing the soil maps. Adherence to National Cooperative Soil Survey standards and procedures is based on peer review, quality control, and quality assurance. Quality control is outlined in the memorandum of understanding for the soil survey area and in documents that reside with the Natural Resources Conservation Service state soil scientist. Four kinds of map units are used in soil surveys: consociations, complexes, associations, and undifferentiated groups. Consociations - Consociations are named for the dominant soil. In a consociation, delineated areas use a single name from the dominant component in the map unit. Dissimilar components are minor in extent. The soil component in a consociation may be identified at any taxonomic level. Soil series is the lowest taxonomic level. A consociation that is named as a miscellaneous area is dominantly that kind of area and minor components do not significantly affect the use of the map unit. The total amount of dissimilar inclusions of other components in a map unit generally does not exceed about 15 percent if limiting and 25 percent if nonlimiting. A single component of a dissimilar limiting inclusion generally does not exceed 10 percent if very contrasting. Complexes and associations - Complexes and associations consist of two or more dissimilar components that occur in a regularly repeating pattern. The total amount of other dissimilar components is minor extent. The following arbitrary rule determines whether complex or association is used in the name. The major components of an association can be separated at the scale of mapping. In either case, because the major components are sufficiently different in morphology or behavior, the map unit cannot be called a consociation. In each delineation of a complex or an association, each major component is normally present though their proportions may vary appreciably from one delineation to another. The total amount of inclusions in a map unit that are dissimilar to any of the major components does not exceed 15 percent if limiting and 25 percent if nonlimiting. A single kind of dissimilar limiting inclusion usually does not exceed 10 percent. Undifferentiated groups - Undifferentiated groups consist of two or more components that are not consistently associated geographically and, therefore, do not always occur together in the same map delineation. These components are included in the same named map unit because their use and management are the same or very similar for common uses. Generally they are grouped together because some common feature, such as steepness, stoniness, or flooding, determines their use and management. If two or more additional map units would serve no useful purpose, they may be included in the same unit. Each delineation has at least one of the major components, and some may have all of them. The same principles regarding the proportion of minor components that apply to consociations also apply to undifferentiated groups. The same principles regarding proportion of inclusion apply to undifferentiated groups as to consociations. Minimum documentation consists of three complete soil profile descriptions that are collected for each soil added to the legend, one additional per 3,000 acres mapped; three 10 observation transects for each map unit, one additional 10 point transect per 3,000 acres. A defined standard or level of confidence in the interpretive purity of the map unit delineations is attained by adjusting the kind and intensity of field investigations. Field investigations and data collection are carried out in sufficient detail to name map units and to identify accurately and consistently areas of about 5 acres. The accuracy of these digital data is based upon their compilation to base maps that meet National Map Accuracy Standards at a scale of 1 inch equals 1,000 feet. The difference in positional accuracy between the soil boundaries and special soil features locations in the field and their digitized map locations is unknown. The locational accuracy of soil delineations on the ground varies with the transition between map units. For example, on long gently sloping landscapes the transition occurs gradually over many feet. Where landscapes change abruptly from steep to level, the transition will be very narrow. Soil delineation boundaries and special soil features generally were digitized within 0.01 inch of their locations on the digitizing source. The digital map elements are edge matched between data sets. The data along each quadrangle edge are matched against the data for the adjacent quadrangle. Edge locations generally do not deviate from centerline to centerline by more than 0.01 inch. U.S. Department of Agriculture, Soil Conservation Service 1985 atlas Washington, D.C.

The survey was evaluated. The soil delineations and map unit components meet national soil survey program standards. NRCS1 1995 Publication film positives were made from the publication film negatives. Digitizing was completed by contract administered by the NRCS, National Cartography and Geospatial Center in Fort Worth, Texas. Area delineations and special soil features were manually digitized from publication film positives, in North American Datum of 1927. The data were then merged into full 7.5 minute quadrangles. The data were formatted in DLG-3 Optional using PC ARC. The digitizing was verified by the National Cartography and Geospatial Center (NCGC) for conformity to specifications prior to final contract approval and released to the state for author error corrections. Author error corrections were resolved by the state soil scientist and indicated on check plots which were submitted to the NCGC for use in correcting the digital data. Digital corrections were made using ARC/INFO 7.0.4. The data were written to DLG-3 Optional format using ARC/INFO 7.0.4. NRCS2, NRCS3 1996 The DLG, DOC, and TAB directories were imported into ARC/INFO 7.0.4 for adherence to standards and specifications. The data were edited. New DLG-3 files were written. The data were archived and distributed for SSURGO. NRCS3, NRCS4 1997 The Map Unit Interpretations Record data base was developed by Natural Resources Conservation Service soil scientists according to national standards. NRCS1 1996 County wide ARC/INFO EXCHANGE files of the 1997 SSURGO data of Klamath County, Oregon, Southern Part were imported to ARC/INFO, Version 8.0 by Natural Resources Conservation Service soil scientist in Tangent, Oregon. ARC/INFO exchange files were projected to Universal Transverse Mercator (UTM), North American Datum of 1983. ARCEDIT was used to adjust soil delineations along water areas in order to fit current imagery. Small water bodies less than 5 acres were considered for removal. Compilation review of the county wide ARC/INFO EXCHANGE files were completed by soil scientists at the state office in Portland, Oregon. NAD83, 7.5 minute quadrangle grid was used to intersect the county wide coverage. Quadrangles were then reselected for the survey area. Quality control routines were completed on all quadrangles for area and special feature coverages. ARCEDIT was used to correct label errors and node mismatches. Digital Line Graph Optional, (DLG-3) files were written. NRCS5, NRCS6, USGS1 2002 The NAD83 DLG-3 files were imported into ARC/INFO, Version 7.21 by certification staff at the Montana Digitizing Unit in Bozeman, Montana. ARCEDIT was used to update boundary segments to current join standards. Minor1 codes were renamed to link the spatial data with the National Soil Information System data base. New DLG-3 files were written. The data were forwarded to the National Cartography and Geospatial Center in Ft. Worth, Texas for archiving and distribution. NRCS6 2003 The National Soil Information System data base was developed by Natural Resources Conservation Service soil scientists according to national standards. NRCS1 2003 The Natural Resources Conservation Service State Soil Scientist or delegate, upon completion of data quality verification, determined that the tabular data should be released for official use.

Classification and Correlation of the Soils of Klamath County, Oregon, Southern Part U.S. Department of Agriculture, Natural Resources Conservation Service 1976 2010 Map Unit Delineations are closed polygons that may be dominated by a single soil or miscellaneous area component plus allowable similar or dissimilar soils, or they can be geographic mixtures of groups of soils or soils and miscellaneous areas. The map unit symbol uniquely identifies each closed map unit delineation. Each symbol corresponds to a map unit name. The map unit key is used to link to information in the National Soil Information System tables. Map Unit Delineations are described by the National Soil Information System database. This attribute database gives the proportionate extent of the component soils and the properties for each soil. The database contains both estimated and measured data on the physical and chemical soil properties and soil interpretations for engineering, water management, recreation, agronomic, woodland, range, and wildlife uses of the soil. The National Soil Information System database contains static metadata. It documents the data structure and includes such information as what tables, columns, indexes, and relationships are defined as well as a variety of attributes of each of these database objects. Attributes include table and column descriptions and detailed domain information. The National Soil Information System database also contains a distribution metadata. It records the criteria used for selecting map units and components for inclusion in the set of distributed data. Special features are described in the feature table. It includes an area symbol, feature label, feature name, and feature description for each special and ad hoc feature in the survey area. Attributes "WT_MIN_FT", "WT_MEAN_FT", and "WT_MAX_FT" refer to the depth below land surface for each soil type. WT_MIN_FT The minimum depth to the seasonal high water table, in feet below land surface. WT_MEAN_FT The mean depth to the seasonal high water table, in feet below land surface. WT_MAX_FT The maximum depth to the seasonal high water table, in feet below land surface. Please note that for each depth to water table attribute, values of "0" should be interpreted as "NULL". Values for depth to water were obtained from the individual soil descriptions reported in Soil Survey of Klamath County, Oregon, Southern Part (NRCS1) for all soils except for soil map units 30, 106, 107, and 108 which were obtained from the Soil Survey Geographic (SSURGO) database (NRCS5). No value was provided from sources NRCS1 or NRCS5 for soil map unit 93B, 94E, 95B, 96B, 97F, 98E, 99B, 100, 101, 102, 103C, 104, 105, DAM, or W (water) and depth to water values for these units have been left blank. Where blank values occur, the value of the attribute is equal to "0". Values of water-table depth reported in these sources are presented either as a range between a minimum and maximum depth, in feet, or as "greater than 6.0 feet", with the exceptions of soil map unit 75 which was reported as "greater than 5.0 feet" and soil maps units 106, 107, and 108 which were reported as "greater than 80 inches." For soils map units that are composed of two or more soil types, each with individually specified water-table depths, the water-table depth attributes reported here were weighted by the proportion of the areal extent covered by each soil type.
