2.04.7 RESPONSE continued THE ADJACENT AREA -The adjacent area to the proposed permit area is delineated on Exhibit AA. (Exhibits Volume II) ae the Hayden Gulch. Dowden Gulch and Dry Creek watersheds. Hayden Gulch and Dowden Gulch both join the Williams Fork in Section 13, T4N.. R89W., at an elevation of 6,800 feet after each flows approximately 4 miles from its origin. Their confluence with the Williams Fork is 0.5 miles downstream of the deactivated USGS stream gage 09249000. Dry Creek joins the Yampa River below the town of Hayden in Section 4, T6N. , R88W. , approximately 12 miles downstream of its origin in the Southern portion of the permit area at an eleva- tion of 6.330 feet. • Six sites were selected for observation of stream flow and water quality to establish apre-permit application water resoaurce data base for the adjacent area. Please refer to Exhibit AA (Exhibits Volume II) for site locations. During the 1983-85 time frame the proposed mining operations would create as affected area of variable extent within the Dowden Gulch watershed. Therefore, monitoring site (S-1) was located is the upper reaches of Dowden Gulch immediately down- stream of the proposed permit area's Southern portion. Another monitoring site (S-2) was located further downstream and immedi- ately above Dowden Gulch's confluence with the Williams Fork. During the 1978-83 time frame, mining operations in the Southern portion of the proposed permit area have created and would maintain an affected area of variable extent within the Hayden Guclh watershed. Therefore. a monitoring site (S-3) was located • in the upper reaches of Hayden Gulch immediately downstream of the permit's area Southern portion. Another monitoring site (S-4) was located further downstream and immediately above Hayden Gulch's confluence with the Williams Fork.
