The Drainage Division maintains the city storm water drainage system, which directs all storm runoff to Denton's three creeks: Cooper, Pecan, and Hickory, which channel it to Lake Lewisville. The Drainage Division is also responsible for closing floodgates, placing high water barricades on city streets during floods.

Drainage programs are paid for by a drainage fee, which is dedicated solely to that purpose.
