Stories with the tag: Hydropower
A new acoustic fish-tracking tag is so tiny it can be injected with a syringe. It’s small size enables researchers to more precisely and safely record how fish swim through dams and use that information to make dams more fish-friendly.

Pacific Northwest National Laboratory will receive more than $6.8 million total over three years to advance the production of renewable power from the movement of oceans and rivers. PNNL will also lead a study looking at the environmental impacts of hydrokinetic and marine energy, which includes tidal and wave power.
