Eel airlift bypass prototype
Prototype design of an airlift developed at CAFL to transport downstream migrant eels through a bypass pipe and away from turbine intakes. The airlift design passes eels as well as a conventional siphon or gravity pipe.

Eel climbing substrate
Left: Prototype ABS plastic eel climbing ramp under development and testing at CAFRL. New substrate design allows for passage of a wider size range of eels with less need for precise flow regulation. Right: juvenile eel climbing wetted ABS plastic substrate.

Eel electrosensitivity test apparatus
Apparatus used to test the sensitivity of eels to low-voltage pulsed DC electric fields. Knowledge of sensitivity of eels to electric fields enables development of behavioral barriers that use electricity to guide eels away from turbine intakes.

Evolution of shoreline around Elwha River mouth
Evolution of the shoreline around the Elwha River mouth, Washington, before, during and after dam removal, 2011–2017. Two large dams were removed from the Elwha River between 2011 and 2014 in the largest dam removal worldwide thus far, releasing more than 20 million tons of sediment downstream.
