Fish: Mill Cr Downstream Trap Results 1992 |
|
Caption: The chart above shows the raw catch downstream migrant trap results for Mill Creek for the spring and summer of 1992. Trapping commenced on 3/4/92 and ran through 7/17/92 and sampling took place on 72 days. Two traps were operated in Mill Creek at times to sample more of the flow and the results above reflect the total of both traps. Chinook juveniles were the most numerous species, followed by dace. Older age steelhead (>70 mm, SH_OLDER) were fairly abundant with 1177 in the season long sample. Coho are present with 153 juveniles captured. AMMOC is ammocoetes or Pacific lamprey larvae. The winter and spring of 1992 were very dry and therefore flows in Mill Creek were low and trapping was relatively efficient. This is reflected by a total catch of over 3000 fish. See the next chart to see the effects of high flow on catch. The data were collected by the Hoopa Tribal Fisheries Department. See the Source Table for complete records including flow, water temperature and hours trapped.
