Water that sustains a stream comes from
underground. Water from rainfall and
snow melt filter down through the earth.
When the water in the soil reaches an elevation higher than the stream
bed, it reemerges and flows down the creek channel. These points of emergence are normally ill
defined and impossible to detect. One
source of water is easily detected and is referred to as a spring.
A spring is a single point where water flows from the
ground. There is usually some type of
noticeable hole from which a trickle of water emerges.
The rate and duration of the spring flow is determined by
the speed and distance the water travels through the ground before
emerging. The subterranean conditions at
Blue Jay Barrens allow for easy water movement.
Underground channels have formed a network of arteries that carry spring
water to the point of emergence. At
times of heavy flow, it’s even possible to hear water gurgling along below
ground. This ease of water movement
means that the flow won’t last and the spring will cease to flow during the dry
season.
The trip through the soil leaves the water clear and
clean. In extremely cold years, the
creek is covered with ice everywhere except where warm spring water enters the
channel. It then becomes easy to locate
the springs because of the abundance of birds that flock there to drink.
Underground channels that feed this spring form a tiny cave
system beneath the soil. There have been
many times that I’ve seen Jefferson ,
Smallmouth and Streamside salamanders disappear into springs. I would imagine this to be an ideal
environment for subterranean salamanders such as these.
