Cathlamet wildlife restoration project to wrap up this fall

Conservationists, BPA work to rebuild floodplain for fish

CATHLAMET — In a pocket of farmland just north of Cathlamet, an environmental group is building a creek they hope will restore the land to its natural state, bring in white-tailed deer and give a boost to salmon recovery efforts.

The Bonneville Power Administration, which supplies 28 percent of the Northwest’s power, recently entered its third phase of a multi-year project with Columbia Land Trust to help restore the floodplain and salmon habitats near the Elochoman River-Nelson Creek area north of Cathlamet. It’s one of several efforts by BPA and its partners to protect endangered species and surrounding wildlife.

In what it hopes will be the final phase of the construction, Columbia Land Trust is digging up land that once teemed with life before it was flattened for agricultural use in the 20th century.

Officials got the go-ahead to build a creek connecting Nelson Creek and the Elochoman River, which they say will make it safer for salmon to spawn and travel back to the ocean.

“What we’re doing is replacing something that did not work efficiently with something that will,” said Simon Apostol, natural area manager with Columbia Land Trust.

The project is a decade in the making, said BPA spokesperson Doug Johnson. Actual construction has occurred for about three years.

“Any time that we can bring back wildlife or help with mitigation, we do whatever we can,” Johnson said.

About 70 percent of the wildlife that once occupied this land is gone, Johnson said. White-tailed deer can no longer rely on the vegetation in this area and are now considered a threatened species. Salmon used to thrive in the natural creeks that were filled to make room for irrigation ditches.

“Salmon are tough, they’re resilient, but now they’re in decline,” said Ian Sinks, Columbia Land Trust stewardship director.

For salmon to spawn and make their way back to the ocean, they need places in the water to lay and then protect their eggs. In a natural river, fallen trees and vegetation provide these spots.

Eventually the new creek, along with the construction of a bridge on Risk Road, will connect two waterways that will not only help salmon but surrounding residents who regularly see flooding.

“I’ve had neighbors tell me that when it floods they sometimes see fish in the middle of the road because they’re trying to get across,” Apostol said.

A more natural habitat is what Columbia Land Trust and BPA are hoping to mimic with the construction of this new creek, Apostol said.

As Columbia Land Trust moves toward the $5.5-million project’s Sept. 30 deadline, construction has focused on creating a wider, healthier creek bed and placing remnants of vegetation inside so it can host wildlife.
