Almost 40 years ago, Scott Nicolai started his stream restoration career taking logs out of the water.
鈥�(Back then) the fish heads 鈥� what I call the fisheries folks 鈥� we stood on the banks, and we looked at the stream. If we saw a big log jam, we thought, 鈥極h, that鈥檚 a barrier to fish. We want the stream to flow,鈥欌�� Nicolai said.
Now, that鈥檚 all changed.
Nicolai, a habitat biologist with the Yakama Nation, is working on the biggest stream restoration effort ever in the Northwest. A project that鈥檚 putting more than 6,000 logs back into remote streams across Central Washington.
The logs will create nooks and crannies where salmon and bull trout can swim and spawn.
"That wood is providing complexity in the water. It鈥檚 providing cover. It鈥檚 creating pools and storing gravel that fish spawn on. Then there鈥檚 aquatic insects that are crawling all over that wood, eating the algae that grows on the wood. It鈥檚 a critical part of the system,鈥� Nicolai said.
The project spans more than 24 miles of streams on the Yakama Reservation and on ceded land owned by private landowners, the U.S. Forest Service and the Washington departments of Fish and Wildlife and Natural Resources.
The rivers and streams have faced historic mismanagement from overgrazing, railroad and splash dam logging and biologists 鈥渃leaning streams out.鈥�
鈥淲e鈥檙e trying to learn from our mistakes and find a better way to manage,鈥� said Phil Rigdon, director of the Yakama Nation Department of Natural Resources.
To take on a project this size, and to reach areas that no longer have roads, the groups are using a helicopter to fly logs from a staging area and place them in the water. It鈥檚 the easiest and cheapest way to complete the restoration.
Biologists use pink and blue flagging tape to guide the pilots. The helicopter blades can be heard from a distance, alerting everyone to move out of the way.
But first, the pilot has to pick up the logs from the staging area. A long cable dangles from the large helicopter. The pilot gently attaches it to four full-size logs below and pulls up. He then flies them about a 1.5 miles away to a section of the Little Naches River where roads no longer reach.
These logs 鈥� a mix of Douglas fir, grand fir and cedar 鈥� come from a timber harvest The Nature Conservancy was using to thin forests far upland.
鈥淲e鈥檙e thinking more towards whole landscape restoration, both the aquatic and the upland,鈥� said Reese Lolley, director of forest restoration and fire for the Nature Conservancy in Washington. 鈥淗ow are we restoring forests? How are we managing forests? And then how do we take some of the wood that鈥檚 coming off and putting it into streams for floodplain restoration?鈥�
The helicopter also helps reach timber that they couldn鈥檛 otherwise get to, Lolley said.
鈥淲e鈥檙e able to source wood from areas where there鈥檚 not access,鈥� Lolley said. 鈥淎nd so there鈥檚 a forest restoration need, but we鈥檙e not able to (otherwise) access or move that wood because it鈥檚 just not feasible or economical to put roads there.鈥�
Some of this wood that鈥檚 now being used for habitat restoration could have been marketable timber. Other logs wouldn鈥檛 have been sold.
Lolley said the thinning will help reduce the risk of mega-fires. Then, instead of leaving that wood in the forest or selling the timber, the wood will help restore fish habitat downstream.
The project is funded by eight different agencies, including the Bonneville Power Administration. It鈥檚 helped along by six different partner organizations, including The Nature Conservancy and Mid Columbia Fisheries Enhancement Group.
鈥淭his project is what will keep our creeks from running dry,鈥� said Kelly Clayton, a habitat biologist with Yakama Nation.
That鈥檚 because the logs will slow the river flow down, allowing it to pool and soak into the water table. The Yakama Nation鈥檚 Scott Nicolai likens these areas to sponges.
The wood helps spread water onto the floodplains and allows them to soak up water and slowly release it into the stream. That stores extra water and cools down warming water.
鈥淏ack in the day, when they ran bulldozers down the creek, cleaning it out, making the water run off faster, that disconnected these floodplains from the river,鈥� Nicolai said. 鈥淲e used to treat our streams like they were just for drainage 鈥� get the water off the land. Now we鈥檙e learning that鈥檚 not such a great idea.鈥�
Nicolai said this type of water storage is vital as the climate warms.
Heading toward the Little Naches River, the group hikes through a dry streambed.
鈥淚 walk across these dips, and I just get excited. If I see gravel in these,鈥� he said, brushing wet leaves away with his foot, 鈥渢hen I think this is where salmon used to be and hopefully will be again in the future.鈥�
For tribal leaders, that鈥檚 the point of these projects. On the banks of the Little Naches as a helicopter whirled overhead, they held a ceremony and said a prayer 鈥� that this project will be successful and the land will return to what it once was.
鈥淚t was very simple: to bring what was rightfully part of this land back to us,鈥� said former tribal chairman Jerry Meninick.
