N.J. Admin. Code § 7:7-12.17

Current through Register Vol. 56, No. 21, November 4, 2024

Section 7:7-12.17 - Dams and impoundments

(a) Dams and impoundments are structures that obstruct natural water flow patterns for the purpose of forming a contained volume of water. Impoundments include dikes with sluice gates and other structures to control the flow of water.

(b) Except for medium rivers, creeks, and streams as defined at 7:7-12.1, the construction of dams and impoundments is prohibited. The construction of these structures is conditionally acceptable in medium rivers, creeks, and streams as defined at 7:7-12.1, provided:

1. The structures are essential for water supply purposes or for the creation of special wildlife habitats;

2. Adverse impacts are minimized; and

3. The structures will not adversely affect navigation routes.

(c) Rationale: Dams can have an adverse environmental impact by reducing the amount of downstream flow and raising salinity levels. Impoundments can reduce the flow of water reaching wetlands or intertidal and subtidal shallows. Therefore, dams and impoundments are prohibited unless essential for water supply or wildlife habitat purposes.
