The character using this spell transforms the ground into water over a large area. In other words, it creates a real lake. The size and depth of this lake depend on the amount of mana (caster level) of the spell.
If there are tall buildings on the ground, then they sink to the bottom of the lake. The ground returns to normal and raises any structures that might be at the bottom of the water when the spell ends.
Maximum Depth: 5 ft per caster level Size: 10 CL = Small lake, 15 CL = Medium lake, 20 CL = Huge Lake"
