Base maps and air photos were supplied by the Surveys and Mapping Branch, Department of Lands, Forests and Water Resources . Special acknowledgement is made to Dr . R . J . Fulton, Geological Survey, Department of Mines and Technical Surveys? Ottawa, for informa- tion in regard to surf icial deposits, and to J . D . Hazlette, District Agriculturist, Salmon Arm, for general information. Participating staff of the Soil Survey Branch were P . N . Sprout, G . G . Runka, I . Cotic, and Dr . M . K . John . Student assistance was given by G . Nielson, W . Skoczylas, M . J . Romaine, L . Sookochoff, and L, G . Rogerson . Laboratory analyses was undertaken by V . E . Osborne and I . Cotic . INTRODUCTION The soil survey of the Shuswap Lakes Area is the beginning of a pioneer soil survey of the Thompson River valley . An interim report published in mimeograph form in 1960 describes the soils of the Shuswap River drainage from Sugar Lake to Mara Lake (1) . In 1963 an interim mimeographed report for the Ashcroft-Savona Area was published (2) . In 1964 a mimeographed report describing the soils of the Eagle River valley was published (3) . This report covers a section of the Thompson River drainage in the Shuswap Lake Topographic Sheet 82 L/NW. Surveys will eventually be undertaken and reports published that will describe other sections of the South Thompson River valley . The field work that began in 1961 was subject to other priorities, thus limiting the acreage classified each year . The field sheets con- sisted of 9 x 9 inch air photos having a scale of two inches to a mile . A map, "Soil Map of the Shuswap Lakes Area", scale two inches to a mile, was prepared . Hand tinted copies of this map are available to government agencies only . Others may obtain uncolored prints at nominal cost from the Department of Agriculture, Victoria, B . C . This report contains a general description of the area, and des- criptions of the soils and their land use . There is also some labora- tory analyses of soil samples, and a glossary of technical terms used in the report is appended . - 2 - HOW TO USE A SOIL SURVEY REPORT Most people are interested only in a few sections of the report . If they thus confine their reading much information will be missed . The material is so organized that information which applies everywhere is given in each section . It is necessary to read the whole report at least once before using any one section as a reference . Farmers living in the area know the soil distinctions on their farms, and on those of some of their neighbors ., However, they cannot compare their own soil types and yields of crops with those in other.
