1. At approximately four (4) square miles in size, Lake Hopatcong is the largest freshwater body in New Jersey

2. Why do we need to dredge? Eutrophication: are natural physical, chemical and biological changes to an estuary, lake or slow moving stream over (geologic) time due to plant material (mostly phosphorus and nitrogen).

3. Man-Made Causes Increased nutrient and sediment loads in stormwater runoff via sheet flow and point source discharges. Nutrients Silts & sediments X-factor = Temperature

4. BMP’s to reduce sediment and nutrient loads Restore/protect the riparian zone. Lake Hopatcong is classified as a trout maintenance waters and has a 150’ RZ. Install and MAINTAIN in-line mechanical sediment traps, like storm-ceptors or vortechnic units. Construct in-line vegetative swales before the stormwater discharges into waterbody. Construct natural fore bays or check dams along upstream tributaries

5. Permits in your tool belt you may need Flood Hazard Area Control Act Rules; 7:13 et al –FHA IP –FHA GP –FHA Permit-by-rule Freshwater Wetlands Protection Act; 7:7A et al –FWW GP 13 –FWW GP 1 –FWW GP 19

6.

10. What’s regulated ?? An activity to remove sediment from the Lake with machinery shall require a Flood Hazard Area Individual Permit. Your compliance statement must address 7:13-11.15. If the activity proposes to disturb freshwater wetlands or freshwater wetland transition areas, than a Freshwater Wetland General Permit 13 shall also be required. Your compliance statement must address 7:7A-5.13

11. Docks Docks, Walls, Boat Ramps Docks are regulated by FHA Permit-By-Rule (b)14. Please see 7:13-7.2(b)14. If there is any proposed disturbance to freshwater wetlands or transition area for the dock, than a Freshwater Wetlands General Permit 19 shall be required. Your compliance statement must address 7:7A-5.19

12. Walls Docks, Walls, Boat Ramps If a portion or the entire wall needs to be replaced, it must be replaced in-kind (same location and materials unless better material exists) and shall require a Freshwater Wetlands General Permit 1 and a Flood Hazard Area Individual Permit.

Your compliance statement must address 7:7A-5.20. In addition, a Flood Hazard Area Individual Permit is required. Your compliance statement must address 7:13- 11.13.

13.
