Just ran across a draft of this written back when I was doing an April poem-a-s-day challenge. I think it cleans up nicely.
Fluid Dynamics
The whirlpool behind Sugar Island dam
where snowmelt drops to the penstock
sends ripples back across the flow,
breaking up the reflection of clouds
trying to move east against the current.
The vortex runs white for a moment,
shredding cumulus, then resumes draining
the sky of blue. The penstock runs north
to the powerhouse, to wring the water’s
watts. What does it wring from the sky?
