ODOT and the Oregon Department of Fish and Wildlife have partnered through a pilot project to improve fish passage, while make critical repairs to aging culverts in western Oregon.
The repairs do not meet full fish passage criteria, but passage is improved at each site. To offset the delay in providing full fish passage, ODOT paid into an ODFW-managed account that will help fund five of the highest priority fish passage projects in the state.
In 2016, ODOT repaired six culverts under the project at a cost of $737,862. Replacing these same culverts through traditional methods would have cost $36.45 million.
Based on the success of the pilot project, ODFW and ODOT are considering expanding the program once the pilot project is complete in 2018.
To maintain the safety of the state highway system, more than 10,000 culverts need repair or replacement, providing opportunity for potential fish passage improvements.
