Surface Water On Permit And Adjacent Areas
The purpose of this section is to briefly explain information
presented in the Surface Water Appendix, Volume 4. The
following five tributary watersheds have been identified within
the Permit Area: Fast Roatcap Creek; West and Main Roatcap
Creeks; Steven's Gulch; Coal Gulch; and Terror Creek. tame
discharges typically occur in March through July, with peak
flows occurring in late April or early May (refer to the Surface
Water Appendix, Volume 4). COVCC monitors continuously
recording stream gauges located within the drainages of the
permit and adjacent areas in accordance with the rr~n~;rements of
Volume 4, Table 1 when accessible.
In conjunction with aerial photograph interpretation, a detailed
field reconnaissance program was undertaken during 1983. Where
ownership permissions were obtained, all surface features were
mapped, field chemistry obtained, and historical use documented.
In addition, randomly spaced, representative surface hydrology
features are monitored on a continuing basis in accordance with
Volume 4, Tables 2 and 3 (see the Surface Water Appendix, Volume
4).
In October, 1991, a surface water resource investigation was
initiated to address the additional permit acreage associated
with Lease ~C-53356. The method of study utilized was similar
to that performed during the study for Lease COC-37210 begun
during 1983 (see the Surface Water Apperxlix, Volume 4).
Additional representative features from this area were
incorporated in the hydrology monitoring network as appropriate.
Coal Gulch is an ephemeral stream which drains approximately 3.3
square miles (2112 acres). Topography is characterized by steep
hillsides in the upland areas and flat to rolling terrain in the
lacer areas. Elevation ranges frwn approximately 8700 ft. to
6000 ft. above mean sea level. Peak stream flows occur during
spring snowmelt and after heavy rain storms. Dissection of the
