Female Pike Caught 10 Miles Of Grand Coulee Dam

A 6.2-pound female northern pike that could have spawned next spring was instead fortuitously netted about 10 miles of Grand Coulee Dam in what’s believed to be the furthest downreservoir capture of the invasive nonnative predator fish so far on Lake Roosevelt.


It and a 27.5-pounder caught near the head of Roosevelt’s Spokane Arm mark temporary victories in the fight to keep the species out of the Columbia River’s anadromous zone.

The two pike were captured by the Colville and Spokane Tribes, respectively, during recent surveys throughout the reservoir and were first reported by KING 5 in a segment that aired last night.

The worry is that the fish will eventually get below Lake Rufus Woods and Chief Joseph Dam, which marks as far upstream as salmon and steelhead can travel on the Columbia, and wreak havoc on ESA-listed Chinook and steelhead at the mouth of the Okanogan River and below.

Tens of millions of dollars have been invested in recovering those stocks and others in the Inland Northwest.

Unfortunately, pike are moving that way as inexorably as water flows downhill.

They were likely moved illicitly by bucket biologists from Idaho’s Lake Couer d’Alene drainage into Washington’s Pend Oreille River, and from there were flushed downstream into the Columbia during high spring runoff.

The species established itself near the mouths of the Kettle and Colville Rivers on Roosevelt, but has been dropping further and further downlake,

They may even already be in Rufus Woods, if anecdotal angler reports are any indication. State fishery biologists are worried about that possibility.

WDFW and the tribes have been working hard for several years to reduce pike numbers, eradicating as many as possible through gillnetting.

The Colvilles are also in the second year of a program that offers anglers $10 a head for any northerns they turn in.

While meant to help protect Lake Roosevelt’s rainbow trout, kokanee and other fish populations, a poster says that any pike caught downstream in Rufus Woods and even the Wells Pool can also be submitted for cash.

The program was the inspiration behind Northwest Sportsman‘s offer of $50 for any caught in Lake Washington, where two have shown up since January 2017.
