Book Description
In 2015, the Alaska Department of Fish and Game (ADF&G), in collaboration with other entities, conducted aerial surveys and operated ground-based weir projects to monitor Pacific salmon Oncorhynchus spp. escapement throughout the Kuskokwim Area. This report presents results of sampling activities and escapement monitoring from all aerial surveys and weir projects operated by ADF&G. Chinook salmon Oncorhynchus tshawytscha escapements were successfully enumerated on 11 tributaries by aerial survey and 7 tributaries with ground-based fish weirs. Above average Chinook salmon escapements were observed at 3 aerial survey locations and 2 weirs. All other Chinook salmon assessments locations observed below average escapement; however, most escapements observations in 2015 were larger compared to recent years. Sockeye salmon O. nerka were successfully enumerated on 3 tributaries by aerial survey and 5 tributaries with ground-based fish weirs. Above average sockeye salmon escapement was observed at 4 of the 8 monitoring location, and below average escapement was observed at the other 4 locations. Chum salmon O. keta were successfully enumerated on 6 tributaries with ground-based weirs. Chum salmon escapement was below average at all monitored locations in 2015. Coho salmon escapements were monitored on 4 tributaries with ground-based weirs. Coho salmon O. kisutch escapement was above average at all monitored Kuskokwim River tributaries. Efforts to monitor coho salmon escapement to the Goodnews River in Kuskokwim Bay were incomplete.

Book Description
The Alaska Department of Fish and Game (ADF&G), in collaboration with other entities, conducted aerial surveys and operated ground-based weir projects to monitor Pacific salmon Oncorhynchus spp. escapement throughout the Kuskokwim Area (comprising the Kuskokwim River and Kuskokwim Bay river systems) in 2017. This report presents results of sampling activities and escapement monitoring from all aerial surveys and weir projects operated by ADF&G and partner agencies Native Village of Napaimute, MTNT, Ltd, and the National Park Service. Chinook salmon (Oncorhynchus tshawytscha) escapements were successfully enumerated on 10 tributaries by aerial survey and 7 tributaries with ground-based fish weirs. Overall, chinook salmon escapement was near average in 2017. A total of 11 chinook salmon tributary escapement goals were assessed; 1 goal was not met, 6 goals were met, and 4 goals were exceeded. Sockeye salmon O. nerka were successfully enumerated on 3 tributaries with weirs. Above average sockeye salmon escapement was observed throughout the Kuskokwim Area. Two sockeye salmon escapement goals were assessed in 2017 and both goals were exceeded. Chum salmon O. keta were successfully enumerated on 6 tributaries with weirs. Chum salmon escapement was near average at 2 locations, above average at 1 location, and well above average at 3 locations in 2017. One chum salmon tributary escapement goal was met and 1 was exceeded in 2017. Coho salmon O. kisutch escapements were incomplete at 2 of 3 monitoring locations due to high waters in 2017. Coho salmon escapement was above average at the George River weir, the only successful monitoring project in 2017. There was no effort to monitor coho salmon escapement in Kuskokwim Bay due to funding constraints in 2017.

Book Description
In collaboration with other entities, the Alaska Department of Fish and Game (ADF&G) attempted to conduct aerial surveys and operated ground-based weir projects to monitor Pacific salmon Oncorhynchus spp. escapement throughout the Kuskokwim Area in 2022. This report presents the results of sampling activities and escapement monitoring from all aerial surveys and weir projects operated in 2022 by ADF&G and the following partner agencies: MTNT Ltd., Kuskokwim River Inter-Tribal Fish Commission, Native Village of Napaimute (NVN), and the National Park Service (NPS). No aerial surveys were flown in 2022 due to a lack of pilot availability and poor weather. Chinook salmon O. tshawytscha escapement was successfully enumerated with weirs on 4 tributaries. Chinook salmon escapement was below average at 3 locations and above average at 1 location. Of the 12 escapement goals for Chinook salmon, 2 were assessed; 1 was met, and the other was exceeded. Chum salmon O. keta escapement was successfully enumerated with weirs on 3 tributaries. Chum salmon escapement was well below average at all locations. One escapement goal for chum salmon was assessed and was not met. Sockeye salmon O. nerka escapement was successfully enumerated using weirs on 3 tributaries. Sockeye salmon escapement was above average at 2 locations and below average at 1 location. Of the 4 escapement goals for sockeye salmon, 1 was assessed and was met. Coho salmon O. kisutch escapement was successfully enumerated with a weir on 1 tributary and was below average.

Sockeye salmon escapement was above the historical average at 3 sites assessed and below average at the other 3. Of the 4 escapement goals for sockeye salmon, 3 were successfully assessed, 1 was met, and the other 2 were exceeded. Coho salmon were successfully enumerated on 2 tributaries using weirs, and 1 escapement goal was assessed and met.

Chum salmon O. keta were successfully enumerated using weirs on 3 Kuskokwim River tributaries. Chum salmon escapements were below average. The only chum salmon tributary escapement goal was assessed and met. Sockeye salmon O. nerka were successfully enumerated on 3 tributaries using weirs and 2 tributaries using aerial surveys. Sockeye salmon escapement was above the historical average at 2 of the sites assessed and below average at the other 3. Two of the 4 escapement goals for sockeye salmon were successfully assessed. One escapement goal was met, and the other was exceeded. Coho salmon were successfully enumerated on 1 tributary using a weir. Coho salmon escapement were above average.

Sockeye salmon O. nerka were successfully enumerated on 3 tributaries by aerial survey and 4 tributaries with ground-based fish weirs. Above average sockeye salmon escapement was observed throughout the Kuskokwim Area. All 4 tributary escapement goals were assessed in 2016 and all 4 goals were exceeded. Chum salmon O. keta were successfully enumerated on 5 tributaries with ground-based weirs. Chum salmon escapement was below average at 2 monitored locations, near average at 2 locations, and well above average at 1 location in 2016. Both chum salmon tributary escapement goals were met in 2016. Coho salmon O. kisutch escapements were incomplete at 3 of 4 monitoring locations due to high waters in 2016. Coho salmon escapement was above average at Tatlawiksuk River, the only successful monitoring project in 2016.

Book Description
The Kuskokwim River drainage is a remote area in western Alaska where Pacific salmon Oncorhynchus spp. return to spawn and play a fundamental role in the local economy and food supply. Each year the Alaska Department of Fish and Game, in collaboration with other entities, operates escapement monitoring projects throughout Kuskokwim River tributaries.
