Wheeler seam, the well is separated from the seam by several
hundred feet of low permeability units.
The Gamba well taps upper Williams Fork sandstones at depths
less than 2b0 feet, and static levels were reported at
133.88 to 184.36 feet below measuring point, or 5,506.12 to
5,455.64 feet above mean sea level, during the period
10-25-73 to 9-28-78.
The Becker well, 1/4 mile southwest of the lease, may tep
upper Mesa Verde sandstones at depths less than 300 feet.
Depth to water is reported at 175 feet. !ising an estimated
elevation of 6,080 feet (USGS Silt Quad), potentiometric
levels would be 5,900+ feet.
The Eastside Mine has ground water inflow from the E coal
seam with the roof and floor not contributing. Flow into
the mine is 2-3 gpm. Horizontal wells were completed into
the D and C coal stringers ar~d the B coal seam, and recoveri•
tests were run (results are found in Appendix J: Corehole
Log and Well Test Analysis). These seams are
stratigraphically above the E seam. Transmissivities were
0.5 gpd/ft for the B seam and 0.26 gpdift for the combined U
and C seams. These values are lower than the
. trar~smissivities found for the Mesa Verde at the Storm King,
Sunlight, and Thompson Creek mines. As a result of the low
transmissivitie5, yields from the formation are generally
below la gpm for we]]s tapping the upper Mesa Verde to the
south of the permit area. Yields for the test wells on the
permit area were below 0.1 gpm. The other adits in Harvey
Gap were either dry or had similar minor ground water
inflows.
Potentiometric elevation of the Eastside Mine seep is 6,350
feet, the D and C seams is 6,366 feet, and the B seam is
6,393 feet. These elevations are following the topography
of the Mine Gulch.
These potentiometric heads indicate a generally southerly
flow direction, parallel to dip, in#o the Piceance Basin.
This direction of flow was also found at the Storm King,
Sunlight, and Thompson Creek Mines along the Grand Hogback.
Depths of water for the probable Wasatch wells also indicate
a southern flow direction parallel to dip. These water
levels are usually lower than ~.~luvial water le~:~el=_. in the
same area, indicating a vertical flow gradient to greater
depths.

Fork and Wasatch formations and the vertical flow gradient
