You can click on the labeled points on the map or locate your watershed in the left column.
The National Climate Data Center keeps climate data for a variety of sites within the state of South
Dakota. The main url for the mapper site is:
https://gis.ncdc.noaa.gov/maps/ncei/summaries/daily
Once on that page, select precipitation on the left column and update the map. You can use the wrench
on the menu on the left to access the map tools menu. You can choose polygon to draw a polygon on
the map to find the weather stations which you can then access on the left menu as shown below.
Alternately, you can access
https://www.ncdc.noaa.gov/cdo-web/
and use the search menus either for the station name or use the map. Once a station is located, you can
query the data available and the form it may be in (daily, monthly, annual, summary statistics, etc.).
Once you identify which station you want, you can access data for download as a bulk text file or month
by month. I chose Brookings and this tab came up. You can choose to add data to your cart for the
station or choose to View Data

Click the large green button that has text ‘Start WSS’. Your pointer starts as a crosshair that you can use
to zoom in on South Dakota or your particular watershed area which you identified from the USGS map.
Once you have the map zoomed in to where you want to find out data, draw you AOI (Area of Interest)
or use the Quick Navigation > Hydrologic Unit (you will need the Hydrologic Unit Code (HUC) from your
USGS gauge description for this.
Once zoomed into this region, you can draw a general AOI (less than 100,000 acres) and access the soil
page which would then list all the soils in the AOI. Find the largest percentage soil type and access that
type. A pop up window will come up with lots of information on the area that you can use in the report.
The information below is for a section of Day County shown on the map.

Description — Map Unit Description
Detailed Soil Map Units
The map units delineated on the detailed soil maps in a soil survey represent the
soils or miscellaneous areas in the survey area. The map unit descriptions in this
report, along with the maps, can be used to determine the composition and
properties of a unit.
A map unit delineation on a soil map represents an area dominated by one or
more major kinds of soil or miscellaneous areas. A map unit is identified and
named according to the taxonomic classification of the dominant soils. Within a
taxonomic class there are precisely defined limits for the properties of the soils.
On the landscape, however, the soils are natural phenomena, and they have the
characteristic variability of all natural phenomena. Thus, the range of some
observed properties may extend beyond the limits defined for a taxonomic class.
Areas of soils of a single taxonomic class rarely, if ever, can be mapped without
including areas of other taxonomic classes. Consequently, every map unit is
made up of the soils or miscellaneous areas for which it is named, soils that are
similar to the named components, and some minor components that differ in use
and management from the major soils.
Most of the soils similar to the major components have properties similar to
those of the dominant soil or soils in the map unit, and thus they do not affect
use and management. These are called noncontrasting, or similar, components.
They may or may not be mentioned in a particular map unit description. Some
minor components, however, have properties and behavior characteristics
divergent enough to affect use or to require different management. These are
called contrasting, or dissimilar, components. They generally are in small areas
and could not be mapped separately because of the scale used. Some small
areas of strongly contrasting soils or miscellaneous areas are identified by a
special symbol on the maps. If included in the database for a given area, the
contrasting minor components are identified in the map unit descriptions along
with some characteristics of each. A few areas of minor components may not
have been observed, and consequently they are not mentioned in the
descriptions, especially where the pattern was so complex that it was impractical
to make enough observations to identify all the soils and miscellaneous areas on
the landscape.
The presence of minor components in a map unit in no way diminishes the
usefulness or accuracy of the data. The objective of mapping is not to delineate
pure taxonomic classes but rather to separate the landscape into landforms or
landform segments that have similar use and management requirements. The
delineation of such segments on the map provides sufficient information for the
development of resource plans. If intensive use of small areas is planned,
however, onsite investigation is needed to define and locate the soils and
miscellaneous areas.
An identifying symbol precedes the map unit name in the map unit descriptions.
Each description includes general facts about the unit and gives important soil
properties and qualities.
Soils that have profiles that are almost alike make up a soil series. All the soils
of a series have major horizons that are similar in composition, thickness, and

arrangement. Soils of a given series can differ in texture of the surface layer,
slope, stoniness, salinity, degree of erosion, and other characteristics that affect
their use. On the basis of such differences, a soil series is divided into soil
phases. Most of the areas shown on the detailed soil maps are phases of soil
series. The name of a soil phase commonly indicates a feature that affects use
or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase
of the Alpha series.
Some map units are made up of two or more major soils or miscellaneous areas.
These map units are complexes, associations, or undifferentiated groups.
A complex consists of two or more soils or miscellaneous areas in such an
intricate pattern or in such small areas that they cannot be shown separately on
the maps. The pattern and proportion of the soils or miscellaneous areas are
somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an
example.
An association is made up of two or more geographically associated soils or
miscellaneous areas that are shown as one unit on the maps. Because of present
or anticipated uses of the map units in the survey area, it was not considered
practical or necessary to map the soils or miscellaneous areas separately. The
pattern and relative proportion of the soils or miscellaneous areas are somewhat
similar. Alpha-Beta association, 0 to 2 percent slopes, is an example.
An undifferentiated group is made up of two or more soils or miscellaneous
areas that could be mapped individually but are mapped as one unit because
similar interpretations can be made for use and management. The pattern and
proportion of the soils or miscellaneous areas in a mapped area are not uniform.
An area can be made up of only one of the major soils or miscellaneous areas,
or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes,
is an example.
Some surveys include miscellaneous areas. Such areas have little or no soil
material and support little or no vegetation. Rock outcrop is an example.
Additional information about the map units described in this report is available in
other soil reports, which give properties of the soils and the limitations,
capabilities, and potentials for many uses. Also, the narratives that accompany
the soil reports define some of the properties included in the map unit
descriptions.
