PAULINA LAKE DAM REMOVAL

RENOVA, and a joint venture partner, were contracted to remove the Paulina Dam on the Paulins Kill River in Blairstown, NJ. This project is part of a broader restoration initiative aimed at improving river connectivity, enhancing water quality, and reducing flood risks. Removing the Paulina Dam, the final step in a three-dam removal effort, has reconnected over 45 miles of river and tributaries to benefit migratory fish species, such as American shad and eel, and local wildlife. 

Constructed in the 1800s, the Paulina Dam was a timber crib, run-of-the-river structure standing 13 feet high and spanning 207 feet across. Decades of sediment build-up created challenges for dam removal, requiring careful excavation and sediment disposal. The project site, situated near Paulina Lake, necessitated strict environmental controls to mitigate impacts to the surrounding ecosystem and floodplain. 

RENOVA’s comprehensive scope of work included the demolition of the dam, excavation of 10,000 bank cubic yards of sediment, and re-establishment of the river’s historical flow path. Restoration tasks included the installation of 4,800 square yards (SY) of erosion control fabric, 2,500 tons of riprap, and 44,400 SY of native seeds and streambank stabilization materials. 

This project not only eliminates a significant hazard and enhances public safety, but also restores the natural flow and habitat connectivity for aquatic life in the Paulins Kill River. The careful planning and execution by RENOVA exemplify the effectiveness of dam removal as a tool for ecological restoration, as well as the skill and resources of this formidable implementation team. 

RENOVA completed work safely with no recordable incidents, on schedule, and on budget. Phase 3 will include regrading the channel bed, installing scour protection at pertinent structures, boulder toe, rock barb, root wad, fascine trench bank protection features, and step pools installation for fish habitat.
