The Temperance River area was first permanently inhabited by Europeans in the 1830s.
Settlers had to decide what to name various geographical features.
When the geographical surveyors came through the area in 1864, they noticed that one particular river ran into water which was so deep that no sand bar formed at the mouth.
Because there was no "bar" that river was named "Temperance."

In the 1930s, the Civilian Conservation Corps built several overlooks at certain places along the riverside.
In 1957, the state organized 539 acres (2.18 km²) of land into Temperance River State Park.
