BARRIER ASSESSMENT TEAM (BAT)

“It is from small streams that big rivers rise.” – Matshona Dhilwayo

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 becoming aware that barriers restricting the movement of aquatic animals and resources must be replaced if we are to be successful in reconnecting the rivers and streams in our watersheds.

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.

While this map is currently a work in progress, it will show the barriers our teams have assessed, where they are located, and their status.

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. Fill out the form below to express your interest and to join our BAT mailing list! Please visit the Events page for information on the next BAT training event in your area.

NOTE: BAT training and assessing culverts require the physical ability to safely navigate road banks that are sometimes both steep and unstable, in a variety of weather conditions. Please contact us if you would like more detailed information about the possible challenges of culvert assessment.

Because culverts can be located in remote areas, please expect significant travel time. While volunteers can be reimbursed for doing assessments, we are unable to offer compensation for travel during training.
