Two river instream hydrokinetic (RISEC) devices were installed in the Kvichak River, Alaska in 2014 to demonstrate the ability to generate hydroelectric power. Fish and wildlife were monitored nearby to describe their presence and to document any negative effects from the devices. Fish were monitored using underwater video cameras and lights mounted to each device; wildlife (birds and mammals) were monitored using shore-based surveys by trained biologists and technicians. Both devices were installed near the village of Igiugig, submerged in the river until sitting on the river bottom, and operated intermittently in August and September.
