over fine to coarse gravel in the upper half of the drainage. Sites: 1(6), 

 2(4), 3(2), 5(3), 6(2), 7(1), 8(2), 9(1), 10(2), 12(24), 13(1), 14(1), 15(2), 

 17(1), 18(1), 19(2), 21(3), 23(38), 24(9). 



Etheostoma maculatum Kirtland. Spotted darter. This species was 

 generally distributed in the lower half of the drainage and often 

 occurred with E. camurum under large slab boulders in moderate to 

 swift current. Harker et al (1979) previously reported the spotted darter 

 from Buck Creek. Sites: 14(3), 19(2), 23(6), 24(1), 25(12), 27(14), 31(1), 

 32(25), 33(1). 



Etheostoma spectabile (Agassiz). Orangethroat darter. One some- 

 what aberrant specimen (INHS 87624) (L. M. Page, pers. comm.) was 

 collected from a small, headwater tributary. Site: 2(1). 



Etheostoma stigmaeum (Jordan). Speckled darter. Harker et al. 

 (1979, 1980) reported the speckled darter from Buck and Brushy creeks. 

 It was generally distributed and was often collected in sluggish runs over 

 a silty-sand substrate. However, adults were occasionally taken from the 

 margins of coarse gravel riffles. Sites: 1(4), 3(5), 5(1), 8(1), 10(7), 12(5), 

 14(3), 16(1), 21(3), 22(2), 23(5), 24(8), 25(5), 27(6), 31(2), 32(5). 



Etheostoma virgatum (Jordan). Striped darter. Harker et al. (1979, 

 1980) reported this species from Buck and Brushy creeks. The striped 

 darter was generally distributed and, as reported by Page and Schemske 

 (1978), is the only slab-pool Catonotus occupying the drainage. Sites: 

 1(20), 3(7), 4(2), 5(3), 7(1), 8(1), 10(2), 11(1), 12(1), 14(3), 15(1), 16(2), 

 17(2), 18(1), 20(1), 21(7), 22(1), 23(5), 24(7), 25(1), 27(4), 29(2). 



Etheostoma zonale (Cope). Banded darter. The banded darter was 

 occasional in the mainstem of lower Buck Creek. We collected it from 

 the interstices of gravel over swift, boulder and bedrock riffles. Sites: 

 23(1), 24(3), 25(2), 27(6), 32(11). 



Percina caprodes (Rafineque). Logperch. The logperch was reported 

 from mainstem Buck Creek by Carter and Jones (1969) and Harker et 

 al. (1979). Generally distributed along the Buck Creek mainstem, it was 

 collected from a variety of habitats ranging from swift, cobble and 

 boulder riffles to a slow flowing, silt covered bedrock pool. Sites: 10(2), 

 19(1), 22(1), 23(1), 24(2), 25(2), 27(4), 31(1), 32(13), 33(2), 36(2), 37(1). 



Percina maculata (Girard). Blackside darter. Since the only collec- 

 tions of this percid were two made in 1955 (C. R. Gilbert, pers. comm.), 

 the species is either sporadically distributed or possibly extirpated from 

 Buck Creek. Sites: 21(1), 27(1). 



Stizostedion canadense (Smith). Sauger. This species was appar- 

 ently sporadic in the lower mainstem of Buck Creek where, according to 

 a local boat dock operator, it is harvested irregularly by fishermen. Site: 

 none. 



Stizostedion vitreum (Mitchill). Walleye. According to a local boat
