Description: The Auke Creek weir near Juneau, Alaska, was operated in 1998 to intercept and enumerate migrating Dolly Varden Salvelinus malma, sea-run cutthroat trout Oncorhynchus clarki, and other species. Abundance for downstream migrant Dolly Varden from March through June was 7,532 and upstream counts from July though early November totalled 4,993, 66% of the emigrating population. Estimated mean fork length of downstream Dolly Varden was 261 mm (SD = 87 mm, SE = 2 mm). Abundance for downstream cutthroat trout in the spring was 374, and the upstream count in the fall was 361. Mean fork length of downstream cutthroat trout was 278 mm (SD = 53 mm) and of upstream cutthroat trout was 282 mm (SD = 58 mm). In the spring, 237 cutthroat trout were successfully PIT (Passive Integrated Transponder) tagged prior to release. The estimated abundance of cutthroat trout 180 mm residing in Auke Lake during July was 247 (SE = 59).
