About this file
This is a soil survey map and detailed soil analysis document from the USDA Natural Resources Conservation Service Web Soil Survey for Thomas County, Nebraska, dated January 23, 2025. The document shows a detailed soil map at 1:1,770 scale covering an 11.3-acre area of interest (AOI).
The soil composition consists primarily of Simeon-Valentine complex (88.4% of the area) with 9-24% slopes, Valentine fine sand (9.4%), and Natick sand (2.2%). The Simeon-Valentine complex is characterized by excessively drained soil with high water transmission rates, no flooding or ponding risk, and low available water supply. The area has a mean annual precipitation of 17-22 inches, mean annual temperature of 45-50 degrees F, and a frost-free period of 120-150 days. This document appears to be supporting information for the Bessey Group Electrical project, providing soil condition details for the campground construction area.

Warning: Soil Map may not be valid at this scale.
Enlargement of maps beyond the scale of mapping can cause misunderstanding of the detail of mapping and accuracy of soil line placement. The maps do not show the small areas of contrasting soils that could have been shown at a more detailed scale.
Please rely on the bar scale on each map sheet for map measurements.

Coordinate System: Web Mercator (EPSG:3857)
Maps from the Web Soil Survey are based on the Web Mercator projection, which preserves direction and shape but distorts distance and area. A projection that preserves area, such as the Albers equal-area conic projection, should be used if more accurate calculations of distance or area are required.

Soil map units are labeled (as space allows) for map scales 1:50,000 or larger.
Date(s) aerial images were photographed: Oct 17, 2021—Nov 5, The orthophoto or other base map on which the soil lines were compiled and digitized probably differs from the background imagery displayed on these maps. As a result, some minor shifting of map unit boundaries may be evident.
