2.04.7(1)(a)(iii)
(b) Specific surface water information.
•
The location of the springs within and adjacent to the Bear :line
permit area are shown on Drawing 2.04.7(2)(a)-1. Note that some
of the springs are located above the "F" seam and some below.
The measured yields of springs and results of water quality
analysis can be found on Table 2.04.7(2)(a)-2, 2.04.7(2)(a)-3, and
2.04.7(2)(a)-4. Spring flows generally decrease from high flora during the early
summer to low flows in the early fall, with many of the springs drying
up during the same period. This is an indication that the
recharge and discharge points of the springs are close together.
The approximate location of decreed springs on and near the
permit area can be found on Drawing 2.04.7(2)(a)-1.
Drawing 2.04.7(2)(a)-2 shows the location of springs in and
adjacent to the Bear r'ine permit area with respect to lineaments,
landslide deposits, and rock fall areas. Easically what this
• map shows is that the springs occur in valleys and the valleys
follow linear trends. The source of the water for almost all
the springs is felt to be discontinuous lenticular sands, because
if only fratures were involved the springs would not he able
to flow for any length of time. Yowever, some of the springs may
also be associated with fractures.
(i) Flow records.
The dip of the beds in the Bear Mine permit area is toward the
main portal in the northeast. As described more fully on page
42, there is no water generated in the Bear Mine. The only
water found in the mine is t'~e result of the dust suppression
system and the mining operation. These small accumulations
do not drain from the mine due to the presence of folding and
local low spots. There is no discharge from the Bear ;line.
~' The mine area is drained by Sylvester Gulch and one other small
ephemeral stream directly into the ':orth Fork of the Gunnison
River which is part of the Colorado River drainage basin, see
