• 2.04.7 - - - -.. RESPONSE continued A monitoring site (S-7) was established on Dry Creek adjacent to the foot of the gulch containing the creek and County Road 53 - approximately 2 miles upstream of the Northern portion of the proposed permit area. Coal is and will continue to be trucked between the two portions of the proposed permit area on County Road 53. The majority of this route (T miles) parallels Dry Creek above S-7. Small amounts of diffused overland flow from some undisturbed areas upslope of the affected area are being temporarily diverted across the drainage divide from Hayden Gulch into an unnamed tributary of Watering Trough Gulch in Dry Creek's headwaters. The water control plan (Ezhibit R. Exhibits Volume I) proposes additional temporary diversions of undisturbed diffused overland • flows in 1981 and 1982. These flows will cross the Eastern boundary of the Southern portion of the proposed permit area and reach tributaries of Drq Creek. Monitoring site S-7 was located below these influxes. A small fraction of the Southern portion of the proposed permit area exists within the headwaters of Temple Gulch, a tributary of Dry Creek. Thin fraction will not contain any affected area. The confluences of Temple Gulch, Dill Gulch, Emrich Gulch and Stoke's Gulch (draining the Western half of the Dry Creek watershed) and the main stem of Dry Creek are located between Monitoring Site S-? and the Northern portion of the proposed permit area. During the 1978-86 time frame, coal preparation and trans- shipping operations have created and will maintain an affected area within the Northern portion of the proposed permit area. • Therefore, a monitoring site (S-8) was established on the lower reach of Dry Creek near the point where it exits this Northern portion. Thin site receives flow from both portions of the pro- posed permit area.
