The department shall consider all the pertinent facts relating to the proposed works which will affect flood control and water resources in the state and shall determine whether the proposed works in the plans and specifications will be in aid of and acceptable as part of, or will adversely affect and interfere with flood control in the state, adversely affect the control, development, protection, allocation, or utilization of the water resources of the state, or adversely affect or interfere with an approved local water resources plan. In the event of disapproval, the department shall set forth the objectionable features so that the proposed works and the plans and specifications for the proposed works may be corrected or adjusted to obtain approval.

2. This section applies to drainage districts, soil and water conservation districts, the natural resource commission, political subdivisions of the state, and private persons undertaking projects relating to flood control.
