I like how they kept part of the natural river flow with the manmade above it.

The Snake River in 1883 was a fearsome
sight for early residents. Baptist
Missionary Rebecca Mitchell described
the river flowing through a “crack in the
earth between solid walls of lava rock.
It dashed upon the rocks, foamed and
roared.”
But, by the mid-Twentieth Century, the
river had been put to work. Dammed and
diverted, it watered land that made Idaho
Falls the hub of an irrigated agricultural
empire.
Power generated by four city-owned
plants is sold to Bonneville Power
Administration and electricity is returned
to the city at reduced rates.
