I'll condense several books into a few sentences. The amniotic fluid amount is usually measured in terms of amniotic fluid index. This is the total of measurements in four quadrants, in centimeters, of the vertical volume of amniotic fluid.

The normal AFI is 8-24. Less than 8 is oligohydramnios (low fluid) and greater than 24 is polyhydramnios (high fluid).

Low AFI can be from decreased production (problem of gastrointestinal tract, urinary system or growth problems) or loss (ruptured membranes).

Elevated AFI can be from several sources (different gastrointestinal problems, placental problems, multiple pregnancies).

Extremely high levels of AFI can be treated by amniocentesis to drain off excess. Mild elevations should just be watched. Low levels may require bed rest, increased fluids and if extremely low, delivery if deemed more beneficial than observation.
