Testing Continues on Upstream Fishway Alternatives

Whooshh fish transport technology to be evaluated through laboratory and field studies

 

 

Watch this video for a demonstration of the Whooshh system that was installed and ready for a field study at the Pinopolis Dam in South Carolina.

Unfortunately, Alden's initial plans to evaluate the Whooshh system onsite were canceled due to the COVID-19 pandemic. The phased research efforts, however, will continue with laboratory studies; secondary evaluations of field installations at St. Stephen Hydroelectric project in South Carolina are scheduled for the spring of 2021.

EPRI and its project partners are funding this research to determine the ability of the Whooshh technology to safely pass American Shad and river herring (both Blueback Herring and Alewife) upstream at hydropower dams. The Whooshh technology is intended as a lower cost alternative to traditional upstream passage fishway designs. The research project's goal are to develop and optimize a volitional entry system for shad and herring and to determine the biological performance of a complete Whooshh system, including passage efficiency, fish health, and migration success.

Starting this month, Alden biologists and engineers will be evaluating a volitional entry system design for its ability to pass river herring into a Whooshh tube for upstream transport. These tests are being conducted in Alden's large flume fish testing facility located on our Holden, Massachusetts campus. Based on behavioral observations and passage data collected during these tests, recommendations for the entry system design and operation will be made for the Whooshh system evaluated in the field next spring.

Check back for more project updates as they become available.
