Earth Calendar for March 26th and March 27th
Where do rivers come from? Generally speaking, from headwater streams—a broad term used to describe a variety of channels and bodies of water which eventually go on to feed the larger river system.
Headwaters can be tiny trickles of water, slow-draining ponds, or bulging and receding meltwaters pouring down from the snowpack. These streams tend to be small, and may shrink and disappear altogether with the seasons. Due to their often low volume and ephemeral nature, many headwater streams are not found on maps, and it may be difficult to detect their presence during certain times of year. While their elusive nature may make these streams seem unimportant, in reality they make up the majority of river miles in the United States—about 53 percent! These streams are vital sources for drinking water, agriculture, wildlife, manufacturing and recreation. About 117 million people in the United States, or one third of the population, rely on public drinking water systems that in turn get some or all of their drinking water from these headwaters and seasonal and rain-dependent streams. Check out EPA’s interactive map to see how much of your county gets its drinking water in part from these streams.
