<br />In WY 2004 the Wes[ Elk Mine monitoring program was operating as designed and provided
<br />adequate data to assess potential Project-induced impacts to the area's hydrologic system, with the
<br />exception of data collected at three surface water stream stations and five monitoring wells.
<br />The data collected from the Upper Deep Creek, Lower Deep Creek, and Upper Dry Fork surface
<br />water stations in WY 2004 aze not reliable due to changing stream characteristics. Pressure
<br />transducers and data loggers were installed in the open stream channels at the Deep Creek stations.
<br />Control channel sections were established at each site. Flumes were not installed at these locations
<br />to limit impacts based on U.S. Forest Service (USFS) conditions. The Deep Creek stream channel
<br />is very dynamic and has changed considerably since the sites were established. As a result of
