The New Jersey Constitution of 1947 (Annotated) Art. VIII, § V, ¶ 1

1. No lands that were formerly tidal flowed, but which have not been tidal flowed at any time for a period of 40 years, shall be deemed riparian lands, or lands subject to a riparian claim, and the passage of that period shall be a good and sufficient bar to any such claim, unless during that period the State has specifically defined and asserted such a claim pursuant to law. This section shall apply to lands which have not been tidal flowed at any time during the 40 years immediately preceding adoption of this amendment with respect to any claim not specifically defined and asserted by the State within 1 year of the adoption of this amendment.
