N.H. Rev. Stat. § 482-A:17
The governor and council, upon petition and only upon the recommendation of the department, may, for just consideration, grant to an owner of shoreline on public waters the right to place fill in the bed of such pond before the owner's shoreline. Every petition to place fill in the bed of public waters shall be filed with the department. The department, after 30 days' notice to abutters, to the local governing body of the municipality in which the property is situated, and to the department of health and human services, shall hold a public hearing. Notice of the hearing shall be published twice in 2 different weeks, the last publication to be 7 days before the hearing, in one newspaper of general circulation throughout the state and another newspaper of general circulation in the municipality, and notice posted in 2 public places in the municipality, and upon appropriate investigation shall make its recommendations to the governor and council with regard to such petition. If the department recommends that the petition be granted, in whole or in part, such recommendation shall include appropriate specifications and conditions necessary to the protection of public rights and to the protection of the rights and privileges of persons owning land in the vicinity of the area to be filled by the petitioner. The grant of the governor and council shall be evidenced by an instrument in writing, executed by the governor and council, attested by the secretary of state, and recorded in the county where the right is to be exercised. Land created by fill in accordance with the grant of the governor and council shall belong to the owner of the natural shoreline as if it were formed by natural accretion. The owner of a shoreline on a public-owned water body may petition the department for the right to place fill below the artificially-created high water level of a public-owned water body to the extent that the flowage rights owned by the state allow.
