Soil Survey of Lincoln County, West Virginia
Use and Management
The Udorthents have been altered to the extent that onsite investigation and
testing are necessary to determine the limitations and potentials for any use. They are
subject to rare flooding (one to five times in 100 years). Maintaining a plant cover and
providing for the proper disposal of surface water help to control erosion and
sedimentation.
Interpretive Groups
Land capability classification: Udorthents—none assigned; Urban land—8s
Woodland ordination symbol: None assigned
Uw—Udorthents, earthen dam
This map unit consists of a raised structure (75 feet in height) of soil material that
was constructed to impound water and protect land against overflow downstream of
Upper Mud River Lake. It is in the central part of Lincoln County. The dam was
constructed with 471,800 cubic yards of soil material that was compacted to medium
density. Both weathered and unweathered sandstone were used as rockfill for the
dam embankment areas.
The dam’s core consists of compacted fine textured soil material that has slow
permeability. Lithologic properties to a depth more than the core material may have
an effect on the performance and safety of the dam; therefore, deeper geologic
investigations of the strata were made to determine these properties prior to
construction of the dam. The flood storage area to the emergency spillway crest of
the dam is 8,850 acre feet. The drainage area of the Upper Mud River Watershed
area is 32,826 acres, and the water surface area of the recreational pool is 306 acres.
The dam was completed in 1992.
