How To Use This Soil Survey
General Soil Map
The general soil map, which is a color map, shows the survey area divided into groups of
associated soils called general soil map units. This map is useful in planning the use and
management of large areas.
To find information about your area of interest, locate that area on the map, identify the
name of the map unit in the area on the color-coded map legend, then refer to the section
General Soil Map Units for a general description of the soils in your area.
Detailed Soil Maps
The detailed soil maps can be useful in planning the use and management of small
areas.
To find information about your area of interest, locate that area on the Index to Map
Sheets. Note the number of the map sheet and go to that sheet.
Locate your area of interest on the map sheet. Note the map unit symbols that are in that
area. Go to the Contents, which lists the map units by symbol and name and shows the
page where each map unit is described.
The Contents shows which table has data on a specific land use for each detailed soil
map unit. Also see the Contents for sections of this publication that may address your
specific needs.

This soil survey is a publication of the National Cooperative Soil Survey, a joint effort
of the United States Department of Agriculture and other Federal agencies, State
agencies including the Agricultural Experiment Stations, and local agencies. The Natural
Resources Conservation Service has leadership for the Federal part of the National
Cooperative Soil Survey.
Major fieldwork for this soil survey was completed in 1995. Soil names and
descriptions were approved in 1996. Unless otherwise indicated, statements in this
publication refer to conditions in the survey area in 1996. This survey was made
cooperatively by the Natural Resources Conservation Service and the Texas Agricultural
Experiment Station. The survey is part of the technical assistance furnished to the Live
Oak Soil and Water Conservation District. The most current official data are available at
http://websoilsurvey.nrcs.usda.gov/app/
Soil maps in this survey may be copied without permission. Enlargement of these
maps, however, could cause misunderstanding of the detail of mapping. If enlarged,
maps do not show the small areas of contrasting soils that could have been shown at a
larger scale.

Cover: The natural gas rig in the background stands in an area of Cotulla clay loam, 1 to 3 percent
slopes. Olmos very gravelly sandy loam, 1 to 8 percent slopes, is in the foreground.
