TRANSCRIPT OF AUDIO
From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of March 8, 2021. This episode is a revised version of an episode from March 2015.
MUSIC – ~11 sec – instrumental
This week, we feature a tune to mark the arrival soon of spring and give a bit of water-credit to the departing winter. Have a listen for about 30 seconds.
MUSIC - ~32 sec – instrumental
You’ve been listening to part of “Winter’s Fall,” by No Strings Attached, on their 1999 album, “In the Vinyl Tradition, Vol. II,” from Enessay Music. In one sense, the “fall” in the title brings to mind the approaching end of winter and the bursts of biological activities that start in spring [SOUND – Spring Peepers - ~4 sec] and continue through summer and early autumn [SOUND – Evening insects in early October - ~5 sec].
But those activities—from frog calling, to insect buzzing, to many human activities—take water, and the water that’ll be available during spring and summer in pools, ponds, streams, and underground depends in large part on the water that falls during winter. About 37 percent of Virginia’s statewide average annual precipitation falls from November through March, according to Southeast Regional Climate Center records from 1895 through 2020. But compared to warm-weather rainfall, winter precipitation is less likely to evaporate rapidly and less likely to be used by plants. As a result, much of winter precipitation can seep into groundwater, recharging supplies that’ll be available in warmer months for plants and as base flow in streams and rivers. Winter recharge of water supplies is even more important in relatively dry—but snowy—western states; in California, for example, typically over 78 percent of the annual average precipitation occurs from November through March, according to records between 1971 and 2000.
While Virginia’s water managers don’t have to focus each winter on snowpack levels, like many westerners do, what falls each Commonwealth winter is still key to our summer water supplies.
Thanks to No Strings Attached for permission to use this
week’s music, and we close with about 20 more seconds of “Winter’s Fall.”
MUSIC - ~22 sec – instrumental

Ice hanging from a tree twig at Heritage Park in Blacksburg, Va., February 20, 2021. This was ice that had collected on the twig during an ice storm and then separated from most of the length of the twig during melting except for a short section that kept the ice attached. This phenomenon was widespread that day in this area.
