Abundance and Run Timing of Adult Salmon in Tanada Creek 1997 Report
Raeder RS. 1997. Abundance and Run Timing of Adult Salmon in Tanada Creek 1997 Report. Copper Center, AK
From June 23 to July 19, 1997 a portable rigid weir was operated on Tanada Creek, a third order perennial stream and a tribuatary to the upper Copper River in southeast interior Alaska. This is the first year of weir operation in a projected three year study. Only partial counts were obtained due to delayed installation, limited personnel and a washout of the weir in a high water event. A total of 20,729 (interpolated to 27,521) sockeye salmon (Oncorhynchus nerka) and two chinook salmon (O. tshawytscha) was counted. Only 16 samples for length and sex were sampled for sockeye salmon and did not constitute a representative subsample.
