Table 13. Summary of occurrence of hydroperiods, PDSI and PHDI drought status, and soil profiles for 23 wells at Hell Swamp that met the hydrology restoration criterion 2010-
2014, one well (91) that met the criterion when 2015 data are included, and were all shown as underlain by non -hydric soils on Beaufort County soil survey. (WH=wetland
hydroperiod, NN= nearly normal, BN= below normal, MBN= much below normal, AN= above normal, and MAN= much above normal). All typical pedons for mapped units in
vicinity of these 17 locations are described as loam (Portsmouth) or fine sandy loam (Arapahoe, Augusta, Dragston) although December and January soil investigation described
fine sandy loam and loamy fine sand. Italics indicate indicator assigned retrospectively based on installation profile and noted post restoration soil changes in vicinity (wells 53, 76,
78, 102, and 105).
Note: The longest hydroperiod at each well in Hell Swamp is depicted as a percentage of the 282 -day (or 283 -day for leap years) growing season when the water table was
recorded as -12" or above for each monitoring year. *At installation of well 101, only 5 inches of soil was able to be augered out; it was too wet for more retrieval.
