Water level or ga(u)ge height or stage is the elevation of the free surface of a stream, lake or reservoir relative to a specified datum .
A water level is a device used for matching elevations of locations that are too far apart for a spirit level to span. The simplest water level is a section of clear tubing, partially filled with water. Water is easily procured for use, and easily discarded after use. The ends are held vertical, and the rest of the tubing lies on the ground or floor. The water level at each end of the tube will be at the same elevation, whether the two ends are adjacent or far apart. Water levels have been used for many years. The water level is lower-tech than the laser level, but it can be more accurate over long distances. To avoid error, all of the water should be at the same temperature. Other sources of error include difficulty reading due to meniscus.
If the water level is used often, dye can be added to the water to make it easier to see. If the water level is used outdoors in winter, antifreeze can be added to the water.
We don't need another water level
We don't need another place to swim
We don't need another world repeating
All the places that we've already been
And now the fish are just too dangerous
And the swimming is much too slow
We don't need another water level
We don't need oh no no no
I've been through the jungle
Many times just today
And I didn't get lost
I've been up to space
With these aliens attacking me
I even fought their boss
But now something smells so fishy
Something ain't right
A new challenge appears
A familiar sight
Oh no, not again
We don't need another water level
We don't need another place to swim
We don't need another world repeating
All the places that we've already been
And now the fish are just too dangerous
And the swimming is much too slow
We don't need another water level
We don't need oh no no no
And now I have to swim again
And get my clothes wet again today
Avoiding killer squid
Seems an evil salmon has torn apart everything
That I already did
And now the baddies are aplenty
And health is rare
So it's back to the surface, back to the surface
Back to the surface to replenish my air
Oh no, not again
We don't need another water level
We don't need another place to swim
We don't need another world repeating
All the places that we've already been
And now the fish are just too dangerous
And the swimming is much too slow
We don't need another water level
We don't need oh no no no
