Coho salmon Oncorhynchus kisutch escapement in the Nome and Niukluk rivers was estimated from counting towers on each river. Coho salmon were also sampled opportunistically from the Niukluk River for age, sex, and length compositions throughout the run using rod and reel, from sport angler catches, subsistence catches, and from carcasses of spent fish. Total coho salmon escapement past the counting tower on the Nome River was estimated at 1,712 fish. The 95% confidence interval for the estimate of total escapement was from 1,361 fish to 2,063 fish. Total coho salmon escapement past the counting tower on the Niukluk River was estimated at 4,633 fish. The 95% confidence interval for the estimate of total escapement was from 4,091 fish to 5,175 fish.
