It is probably subject to temperature increases, nutrient loading, and siltation from the surrounding farms and ranches. No fish inventories for Dry Creek have been undertaken. However, the aquatic habitat may be suitable for chubs, Gila spp.; shiners, Notropis spp.; and suckers, Catostomus spp.; and, other rough fish." Benthic invertebrates and periphyton were sampled in May and November 1974 in association with Seneca Coal Company's application for Permit No. C-82-057 for the Seneca II -W Mine. Site D-3 was located in Dry Creek approximately 5.0 miles upstream of the Loadout Permit Area and at an elevation increase of only 160 feet. Because this is the only aquatic habitat data available on Dry Creek, the sampling results from Site D-3 are considered representative of the reach of Dry Creek that bisects the Permit Area and are summarized herein. Reference may be made to Attachment 11-2 for a description of sampling methods and summary of results (this information duplicates Permit C-82-057 at Vol. 6, Tab 11, pp. 12-13 and Table 11-24, 11-25, 11-33, 11-34 and 11-35). Pool bottom fauna collected at Site D-3 in May 1974 was not abundant. Eight taxa representing five orders of benthic invertebrates were captured using a dip net. The sample was dominated by baetid mayflies with lessor catches of limnephilid caddisflies, simulids, and tupulids. The November sample of pool bottom habitat also produced few organisms; 10 taxa representing nine orders of benthic invertebrates were captured. Amphipods and Ephemeropterans (baetid mayflies) represented over 60 percent of the relative abundance. A second sample of riffle habitat in November, 1974 revealed greater numbers and diversity (21 taxa from 10 orders). The riffle sample was strongly dominated at 68.4 percent relative abundance by caddisflies, and primarily the genus Hydropsyche. Certain species RN17-05 11-11 Revised 12/17
