Twenty-three observation wells were installed at 12 sites in the Reelfoot Lake area of Tennessee and Kentucky during July 1986. The wells were installed to supplement the existing water-level network and to provide additional data on the hydraulic characteristics and vertical hydraulic gradients in the alluvial aquifer near Reelfoot Lake. Well yields ranged from less then 20 gallons per minute to about 140 gallons per minute. Specific capacity ranged from less than 1 to 17.1 gallons per minute per foot of drawdown.

Three stratigraphic sequences were encountered during drilling. Clay and silty clay was about 40 feet deep near the southwest corner of Reelfoot Lake. Predominantly medium- to coarse-grained sand occurred below about 15 feet of silt and clay near the west and northwest sides of Reelfoot Lake. Along the western limit of the study area, near Lake No. 9 and the Mississippi River, about 20 to 30 feet of silt and silty sand occurred below land surface.
