The Tazimina River sometimes referred to at "The Taz" flows through the southern end of Lake Clark National Park and Preserve from Lower Tazimina Lake to Sixmile Lake. The river is home to rainbow trout, arctic grayling, dolly varden, lake trout, northern pike, sockeye salmon. Sockeye escapements have been declining. Tazimina River's most grand feature is Tazimina Falls, 9 miles up river, and the power plant along them.
The hydro plant was started in 1996 and completed in 1998. It mostly consist of a 5ft diameter pipe which lies inside a shaft, 26 feet wide and 120 feet deep. From the base turbines discharge water through a 230 foot tailrace tunnel back into the river at the base of the falls. The plant produces up to 824 kilowatts (kW) and is expandable to 1.5 megawatts (MW). It's powered by run of the river (no reservoir).
