Barrier Assessment Team (BAT)
Background
The U.S. Supreme Court has ruled that Washington State must fund the work necessary to replace all culverts on state land that represent a significant barrier to migrating fish. Although the ruling applied only to state lands, all landowners, including federal, county and private, are now aware that barriers restricting the movement of aquatic animals and resources must be replaced.
Given that there are as many as 40,000 culverts around the state, and not all are equally harmful to fish, there is an immediate need to assess and prioritize culverts for replacement based on their impact and potential for improvement.

BAT Program
WCTU is deploying teams of volunteers to conduct assessments of culverts and other structures that are potential barriers to fish passage using the Washington Department of Fish and Wildlife (WDFW) protocol. By partnering with organizations like the United States Forest Service (USFS), counties, Tribes, and the United States Geological Survey (USGS) to evaluate and classify culverts on lands that they manage, we aid in developing a comprehensive plan to prioritize the replacement or redesign of culverts that disrupt the movements of aquatic creatures and resources. The Council has invested in a number of survey kits across the state to equip Barrier Assessment Teams in their work, using modern equipment to provide accurate data.
Additionally, all collected survey data is managed in a Geographic Information System (GIS) that will allow us to track the results of barrier surveys and share them with interested people. Survey data that determines a culvert is a potential barrier to fish passage are shared with the WDFW, allowing them to update their own fish passage barrier database.

The Council is actively training volunteers to participate in field teams of 2-3 surveyors. Training consists of a virtual training session followed by in-field training to cover safety, equipment usage, data gathering, and reporting. Please visit the Events page for information on the next BAT training event in your area.

Training Day:
Wear footwear that are comfortable, provide good stability, and that you are comfortable getting wet or that is waterproof.
Bring sunscreen, hat, sunglasses, and a change of footwear if you can.
Drink plenty of water and be sure to bring snacks or a lunch!
Printing Forms:
Print the Level A form on one side of a piece of paper, then print the Site Description “upside down” on the back of the same page. This makes it easy to flip between the two when on a clipboard in the field!
While it’s not necessary to use Rite in the Rain weatherproof paper for all the forms you print, it’s a good practice to have some weatherproof forms available for when it’s raining, or it’s wet enough to smear your writing.
Use pencil lead for all forms regardless of paper type. When creating weatherproof forms, use #20 white ‘Rite in the Rain’ copier paper
When creating weatherproof forms, it’s important to use a laser printer – not an inkjet printer!

What to Expect on Training Day
Dannon Elora - 19 July 2022
Traveling to Darrington for Barrier Assessment Training was a journey that ended up being full of unexpected meaning for me. Memories of a land I had forgotten from childhood trips to Oso rose up around me in the form of mountains and general stores, rivers and bridges that we had floated under in tubes or rafts. Even the scent of the woods reminded me of warm summer days spent along the riverside, turning over rocks to see “periwinkles”, which I now know are caddisflies, and picking blackberries for my grandpa’s famous pies. It was just as striking to see how much had changed in my absence, too; the Oso slide, visible from the highway, was a stark and foreboding reminder of how very alive and dynamic this landscape was.
At Moe’s, a delightful cafe with friendly staff and great places to spend time with family and friends, the newest set of trainees and experienced assessors met under sunny skies, eager to learn. After introductions and with a game plan in mind, we traveled to our first culvert. Though eager, I was a little nervous— my background was primarily in human-facing, customer service-type roles and technology rather than field work, but this turned out to be no problem at all! Willingness to learn and to do a little forest exploration with integrity are all that are needed to help this cause.At our first stop, we learned about the equipment we would be using, the process of assessing a culvert, and things to look out for during assessments. All the while, we were surrounded by nearly silent forest, with only the occasional passing car to remind us we were in a public space. Dividing into groups, some of us navigated down to the culvert, while others wrangled the data, and collectively bonded over the beauty of the place we found ourselves in.
Our next two stops were equally stunning, and through our work and our conversations, it was clear what we were doing was vitally important. Although many of us were interested in helping and protecting fish, learning the history of undersized culverts causing flooding, breaking down roadways, and destroying surrounding habitats, made it clear that this service is crucial not only for conservation and restoration, but the safety of our fellow adventurers and recreationalists.
To make the trip as fun as possible, I highly recommend bringing along plenty of water, clothes that are comfortable for climbing, crouching, and reaching and appropriate for the day’s weather, knee-high boots, waders, or shoes you are comfortable getting wet, sunscreen, and plenty of snacks or lunch to eat!
