1984 Newhalen River adult salmon enumeration program
Poe PH and Rogers DE. 1984. 1984 Newhalen River adult salmon enumeration program. FRI-UW-8415. University of Washington, School of Fisheries, Fisheries Research Institute. Seattle, WA
The escapement of sockeye salmon to spawning areas of the Newhalen River-Lake Clark syste above RM 22 was estimated by a systematic visual enumeration program for the fifth consecutive year. The escapement estimate of 3.1 million, which represents 29.5 percent of the 1984 Kvichak River system escapement of 10.5 million, was the largest counted escapement at RM 22 since our observations began in 1980. A limited index counting program was also conducted at RM 1. After 7 days of counting at RM 1 a projected total escapement of 3.5 million was made. This estimate compared closely to the total escapement estimate of 3.8 million to the Newhalen River-Lake Clark system based on the RM 22 escapement enumeration program together with spawning ground counts of spawners below RM 22. Results from the 1984 Newhalen River escapements studies are compared to previous years and the recent production of Newhalen River-Lake Clark system is examined.
