- Columbia Basin Fish Passage Data Analysis
We screened available fish passage assessment and habitat confirmation reports and the provincial fish passage database (PSCIS) for barrier crossings to summarize the crossings in the Fish and Wildlife Compensation Program operational area of the Columbia Basin with the greatest potential for remediation.

The health and viability of freshwater fish populations depends on access to suitable spawning, high water refuge, rearing and overwintering habitat. Additionally, watershed connectivity is important to accommodate population abundance fluctuations and the flow of genes that provides resilience to environmental stressors such as floods, landslides and temperature fluctuations. Closed bottom road crossing structures (culverts) can present barriers to fish migration due to increased water velocity, turbulence, a vertical drop at the culvert outlet and/or maintenance issues. Rehabilitation and replacement of crossing structure barriers can provide access to currently isolated high value habitats.
We screened available fish passage assessment and habitat confirmation reports and the provincial fish passage database (PSCIS) for barrier crossings to summarize the crossings in the Fish and Wildlife Compensation Program operational area of the Columbia Basin with the greatest potential for remediation. We identified 116 fish passage restoration opportunities for follow up. Of these, 31 have completed the habitat confirmation stage and through the process were rated as high or moderate priorities for remediation. These projects are ideal candidates for funding from a variety of programs as they are near shovel ready requiring only the design and remediation stages. Eighty-five of the crossings we identified have completed the fish passage assessment stage. These 85 crossings could be considered for the next phase in the remediation process which involves confirmation of high value habitat and in many cases also the confirmation of fish presence.
Currently, on non-forestry related roads in British Columbia, Land Based Investment Strategy funding administered through British Columbia Timber Sales is available only for the assessment and habitat confirmation phases of the remediation process and not for the design and installation of replacement structures. This highlights a need to identify other stakeholders and alternative sources of funding to facilitate these remediation steps on local, highway and other non-forestry related roads. We identified local stakeholder groups in the basin that could potentially collaborate with regulators, government agencies and local professionals to remediate some of these sites. Also, we detailed potential funding programs that could provide support for the work required to assess, plan and remediate the crossings.
It is hoped that the information in this document will be useful to some of the identified stakeholder groups as well as local professionals, government agencies and regulators to help restore connectivity to valuable fish habitats in the basin.
