Section NR 346.07 - Procedure

(1) FEE SCHEDULES.

(a) Application fees shall be submitted as a part of a complete application for a contract to remove material from the beds of natural lakes. The application fee shall be remitted to the applicant if the requested dredging contract is denied.

(b) Noncommercial fees shall be submitted by the applicant upon receipt of the contract from the department.

(c) Commercial removal fee shall be submitted in annual installments based upon the charge specified in the contract per cubic yard times the number of cubic yards of material removed under the contract for that calendar year. Quantities removed will be measured in its original position, computed by the method of average end areas, with no correction for curvature, or by the method of truncated prisms.

Note: The methods of measuring the amounts of bed material removed during commercial projects were obtained from, "State of Wisconsin, Department of Transportation, Division of Highways, Standard Specifications for Road and Bridge Construction, Edition of 1975, Section 208.4 Method of Measurement", page 103.

The following excerpt from, "Elementary Surveying, 5th Ed.", by Russell C. Brinker, pages 477 & 478, presents formulas for the methods of calculation specified by the Wisconsin department of transportation and incorporated in NR 346.

End-areas formulas. The volume between 2 vertical cross sections A1 and A2 is equal to the average of the end areas multiplied by the horizontal distance L between them. Thus:

Ve =L(A1) A2) cu. yd.

2 x 27

This formula is approximate and gives answers which generally are slightly larger than the true prismoidal volumes. It is used in practice because of its simplicity. Increased accuracy is obtained by decreasing the distance L between the 2 sections. When the ground is irregular, cross-sections must be taken closer together.

Prismoidal formula. The prismoidal formula applies to the volumes of all geometric solids which can be considered prismoids. Most earthwork volumes fit this classification but relatively few of them warrant the precision of the prismoidal formula, which is:

Vp =L(A1) 4Am) A2)

where Vp = volume;

A1 and A2 = areas of successive cross-sections taken in the field;

Am = area of a section midway between A1 and A2;

L = horizontal distance between A1 and A2.

(2) BONDS.

(a) Bonds in the amount specified in the contract received by the applicant shall be secured by the applicant and submitted to the department of natural resources prior to any removal of material by the applicant on the contract issued by the department.

(b) Upon the successful completion of the dredging contract the applicant shall request a release from the bonding requirements. The department shall inspect the dredging site. If the department determines that the contract has been satisfactorily completed, the department will advise the applicant and bonding company that the bond may be canceled.
