Hydraulic design and safety requirements. NR 333.07(1)(1)
Minimum hydraulic capacity. Except as provided in
sub. (2), all proposed and existing dams shall have the minimum hydraulic capacity shown in Table I:
-
See PDF for table 
NR 333.07(2)(a)(a) Unless the department determines that public safety requires full compliance with the substantive requirements of this rule, all dams which will be submerged by flows less than the minimum hydraulic capacity specified in Table I shall be designed to pass the flow of the river at submergence.
NR 333.07(2)(b)
(b) Any owner may provide documentation to justify a different spillway capacity from that specified in Table I. The department shall review such documentation and may approve the spillway capacity proposed by the owner if it determines that such capacity will not result in an additional hazard to life, health or property when compared to the capacity specified in Table I.
NR 333.07(3)
(3) Safety measures. The owners of all new and existing dams shall comply with the following safety measures:
NR 333.07(3)(a)
(a) The owner shall have an adequate operation, inspection and maintenance plan for the dam.

(b) The dam shall be structurally stable for any flow condition up to and including the design flood flow.
NR 333.07(3)(c)

1. A notification flow chart identifying involved agencies, other dam owners both upstream and downstream and their phone numbers.
NR 333.07(3)(c)3.
3. An inundation map of the hydraulic shadow on a scale of l" = 2000' or less that extends downstream to an elevation within one foot of the dam nonexistent profile.
NR 333.07(3)(c)4.
4. Procedures for notification of all property owners affected by a dam failure and a list of their names, addresses and phone numbers.
