Notes:
1. Parameters monitored as a result of TR-54
2. Added to baseline analyses in 1996. Not for analyses completed prior to 1996.
3. All azameters will be anal zed for then dissolved form unless stated otherwise.
4.3 Surface Water Monitoring
The WEM area is drained to the north by the North Fork of the Gunnison River, to the south by
Minnesota Creek, to the west by Gribble Gulch, and to the east by Deep Creek and Raven Gulch. The
current surface water monitoring plan for the WEM includes 22 stream stations, comprised of 10 sites
with continuous recording devices and 12 sites with instantaneous flow measuring devices. MCC plans
to add 2 new surface water monitoring sites in the SOD (PR-10) area in 2006: the Deep Creek Ditch
Flume and the Minnesota Reservoir Flume (Map 1 and Table 7).
