Going out to investigate flood damage is never a fun
job. I’ve done it enough times to know
what I’ll probably find and I rarely overestimate the damage. The fastest way to reach the creek is to
follow the small tributary that begins behind the house. Following the storm last Friday, the amount
of water flowing behind the house was more than I have ever seen. I knew I was going to be viewing the effects
of a record flood, so I wasn’t surprised to see supportive evidence of that as
soon as I started down the trail. Loose
Indian Grass stalks, left on the trail after mowing the adjacent field, were
lined up along the edge of the trail to a point where a water stream that
escaped the normal channel carried the grass stalks off into the shrubs.
This brush pile is far to the side of the normal tributary
channel. Flood water left debris right
at the edge of the pile and cleaned most of the loose material from the ground
as it swept along.
The channel is to the right, but most of the water left the
channel and went through here. Water has
followed this route before in a stream five or six feet wide. In this case, the stream was closer to 30
feet wide.
The stream never made its way back to the tributary. Instead, the tributary continued to divert
excess water into this independent flood stream. As the water volume increased, the velocity
increased and the water stripped the ground clean of anything that would move.
The result was not a very pretty sight. Plants left in place all point toward the
departing water. All of the decomposing
organic matter, once destined to provide nutrients for the growing plants and
the soil ecosystem, has been washed away.
This disruption will be noticeable for at least a year.
The bare ground was once covered by moss, a plant that
doesn’t have enough hold on the soil to withstand the force of moving
water. Through the center of the photo
is the boundary between moving water on the left and the area of no inundation. This condition has occurred on a small scale
in the past, but never close to the extent resulting from this storm.
The path of destruction follows straight down towards the
main creek. It seems only appropriate
that a deer skull should preside over the devastation. After viewing this, I’m not sure I’m ready to
see what happened along the creek itself.
