Stream Flow Findings Benefit Alaska Salmon Stocks

The Takeaway: A Hollings Scholar’s project at the Kachemak Bay Research Reserve will help resource managers better manage Chinook salmon.

On Alaska’s Kenai Peninsula, the Anchor River’s May-to-September run of Chinook salmon is highly anticipated by sport fishers, and by commercial fisheries that market the catch as king salmon. But with uneven yields in recent years, resource managers are working overtime to stem overfishing and keep salmon stocks sustainable. At the Kachemak Bay National Estuarine Research Reserve, stream-flow findings developed by a NOAA Hollings Scholar will help marine life experts ensure that Chinook salmon run the river year after year.

Making use of existing research reserve data, the Hollings scholar created an Anchor River “discharge rating curve,” which forecasts stream flow along several points into the estuary mouth. An Alaska Department of Fish and Game biologist says the rating curve will help the agency make earlier and better-informed decisions during salmon-spawning season. (2019)
