TRANSCRIPT OF AUDIO

From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of April 5, 2021.  This revised episode from April 2016 is part of a series this year of spring-related episodes.

SOUND – ~7 sec - Kayaking on the Appomattox River, recorded from underwater.

This week, those sounds above and below the surface of the Appomattox River open an episode about spring signals on and in Virginia’s water bodies. Have a listen for about 10 seconds to the following mystery sound, and see if you can guess what group of water-resources users this signal is designed to alert.  And here’s a hint: it’s a powerful signal, for reel...and rod.

SOUND - ~11 sec

If you guessed, a signal for people fishing, you’re right!  You heard a June 2013 recording of a warning siren at the Claytor Lake hydroelectric facility on the New River in Pulaski County, Virginia.  The siren was being used to alert anglers and any other nearby river users that a power-generating unit was about to start operating and releasing more water.

While that siren sounding was a human-generated signal to stop fishing in that location, spring in Virginia sends out plenty of natural signals that serve to start or increase fishing activity.  Anglers follow fish, and fish follow various environmental and biological cues, such as temperature, daylight, sources of insects and other food, predator behavior, and life-cycle demands.  Spring brings significant changes to those fish cues, and as a result, gives many anglers their cue to resume trying to outwit the finned inhabitants of the Commonwealth’s ponds, lakes, streams, rivers, and coastal waters.

Thanks to Raven Harris for the Appomattox River sounds.  We close with some music for Virginia’s anglers.  Here’s about 25 seconds of “Bass Fisherman’s Reel,” an adaptation of a traditional tune called “Fisher’s Hornpipe,” done by Williamsburg musician Timothy Seaman on his 2004 album, “Virginia Wildlife.”

MUSIC - ~28 sec

SHIP’S BELL

Virginia Water Radio is produced by the Virginia Water Resources Research Center, part of Virginia Tech’s College of Natural Resources and Environment.  For more Virginia water sounds, music, or information, visit us online at virginiawaterradio.org, or call the Water Center at (540) 231-5624.  Thanks to Ben Cosgrove for his version of “Shenandoah” to open and close the show.  In Blacksburg, I’m Alan Raflo, thanking you for listening, and wishing you health, wisdom, and good water.
