Hydroelectric Power

I’m pleased to announce the launch of my first-ever sound effects library entitled Hydroelectric Power. Witness the power of water in this collection of recordings captured at and inside historic hydropower plants and massive concrete dams in the United States.

In the American West, water scarcity and allocation are hot topic issues. Gain access inside a working powerhouse along the Boise River as one of three generators, producing over 1,000–kilowatts of power, crank up from a cold start in advance of the irrigation season. Get hit in the face with spray from Shoshone Falls, a waterfall taller than Niagara Falls, during a high water event. Stand 100 yards downstream from the massive Bonneville Lock and Dam along the Columbia River in Oregon as 3,487 Kgal/sec rush past, generating 624 megawatts of power. Listen to the thunderous sound of Gorge Dam along the Cuyahoga River. Yes, the river that caught fire. This decommissioned 60-foot tall, 400-foot-wide dam has sat idle for over 50 years. Plans are in the works to remove it, thereby freeing up the flow of the snaking river from its headwaters to Lake Erie.

Admittedly, waterfalls and dams recorded up close can sometimes sound a lot like white noise. Yet there are distinctions. In Hydroelectric Power, each sound takes on the character of its environment, making it unique to that space and time.

These recordings, captured by field recordist Richard Alan Hannon, will complement your documentary, film and game design needs until, unfortunately, the rivers run dry. Seamless loops have been meticulously crafted from sounds that allow for it, providing more opportunities to utilize these sounds in your projects.

  • along the Boise River east of the city of Boise, Idaho
  • Sound Devices 702 with Clippy EM 172 in binaural head and SM 58, plus Sony PCM D100
  • 68 dBA 192 feet (59 m) downstream from the spillway, 73.5 dBA inside the powerhouse at the turbine
  • the dam, measuring 68 feet (21 m) high and five hundred feet (152 m) in length, was constructed in 1908 to divert irrigation water into the New York Canal
  • 3 turbines in the powerhouse generate 3.45 MW of electricity. Only one is operating in recordings.

  • along the Snake River in south-central Idaho
  • Sony PCM D100 with Luhd PM-01AB on quasi-binaural head
  • captured May 2, 2018, 1,140 feet (348 m) from the waterfall
  • discharge over falls, 8,000 cubic feet per second (cfs)!

Shoshone Falls, along the Snake River in Twin Falls, Idaho, is 212 ft (65 m), taller than Niagara Falls. Spring runoff in May 2018 was particularly high. Much of this water is used for hydroelectric power and irrigation. Read more at Wikipedia.
