In September 2021, Natel conducted formal testing with PNNL on a cohort of American eel passing through the RHT test unit operating at 670 rpm under 10 m of hydraulic head. Following the test the eels were monitored for 48 hours with 100% survival.
Freedom Falls RHT is installed and operational, fish passage testing is ongoing, Natel received a DOE grant to research Restoration Hydro, and Upstream Tech launched HydroForecast.
