WALLKILL RIVER WATERSHED MANAGEMENT GROUP Clove Acres Lake / Clove Brook Watershed Restoration Plan NJDEP Project RP05-090 November 2008 Prepared By: Ernest Hofer, PE Nathaniel Sajdak Watershed Specialist Watershed Coordinator WALLKILL RIVER WATERSHED MANAGEMENT GROUP Sussex County Municipal Utilities Authority 34 South Route 94 Lafayette, New Jersey 07848 973-579-6998 www.wallkillriver.org Acknowledgements The developed Restoration Plan for the Clove Brook Watershed, including Clove Acres Lake / Lakeshed was developed with significant services from Princeton Hydro, LLC regarding the conducted Clove Acres Lake Characterization and Lakeshed assessments as well as input and support from many community contributors. The Wallkill River Watershed Management Group (WRWMG) wishes to acknowledge the following individuals and organizations for their help and valuable assistance in the development of the Clove Brook Watershed Restoration Plan: • Chris Mikolajczyk and Dr. Fred Lubnow of Princeton Hydro, LLC • Dana Cartwright, Kim Cenno, and Marco Al-Ebus of the New Jersey Department of Environmental Protection (NJDEP) • David Kunz and Sara Weinrich of the Sussex County Office of Geographical Information Systems • Jeff Card of the Sussex Borough Department of Public Works • Kent Hardmeyer of the Natural Resources Conservation Service (NRCS) • Frank Hennion of the New Jersey Forest Service • Edward Henry of United States Fish & Wildlife Service, Wallkill River National Wildlife Refuge • Steve Komar of the Rutgers Cooperative Extension of Sussex County • Wini Straub of the Sussex County Soil Conservation District • John Hatzelis of the Sussex County Municipal Utilities Authority (SCMUA) • Board of Commissioners, Sussex County Municipal Utilities Authority Acknowledgements are also due to Patricia Kehrberger and Brian George of HydroQual, Inc. for technical support and stream flow measurements, to Harvey Klein of Garden State Laboratories for analytical services, and to John Nugent, Angelo Baron, and Joseph Kinney of the SCMUA Wastewater Treatment Facility for supplying the necessary stream instrumentation devices, calibration and laboratory support services. Funding was provided by a Grant from the NJDEP and extensive in-kind services and support from the Sussex County Municipal Utilities Authority (SCMUA) and the SCMUA Board of Commissioners. Profile of the Wallkill River Watershed Management Group (WRWMG) In 1994, the Sussex County Board of Chosen Freeholders designated SCMUA as the lead agency to develop a Wallkill River Watershed Management Plan. As a result, in March 2000, the NJDEP awarded a contract to the SCMUA to facilitate the Wallkill River Watershed Management Project and bring together local stakeholders to work in partnership to develop a plan to insure the restoration, maintenance and enhancement of the waterways within the Watershed. Over the past eight years, unique stakeholder partnerships have been established and a strong sense of stewardship towards the watershed has been generated. Most importantly, the stakeholders have formed the WRWMG. The key roles of the WRWMG are to: 1. Raise watershed awareness and promote environmental stewardship 2. Generate stakeholder participation in watershed management initiatives 3. Conduct water quality monitoring of local watershed surface waters 4. Drive efforts for potential “on the ground” watershed restoration projects 5. Serve as a Watershed management and water quality liaison for the public residents, municipal officials, and county government organizations i Table of Contents Section Subject Page Acknowledgements i Profile of the Wallkill River i Watershed Management Group (WRWMG) Executive Summary 1 Project Description Introduction 10 Background 10 Project / Watershed Objectives 13 Translation of Project / Watershed Goals into 16 Management Objectives Clove Acres Lake / Clove Brook -
