2021 Lake Hopatcong Water Quality Report released

February 10, 2022| Environment

By: Holly Odgers

The 2021 Lake Hopatcong Water Quality Report has been released. The monitoring was conducted by Princeton Hydro and funded by the Lake Hopatcong Commission. Regular water quality monitoring has been conducted on Lake Hopatcong since the 1980s. 

As stated in the report, the Lake Hopatcong Water Quality Monitoring program "is valuable in terms of continuing to assess the overall “health” of the lake on a year-to-year basis, identifying long-term trends or changes in water quality, and quantifying and objectively assessing the success and potential impacts of restoration efforts.  In addition, the in-lake water quality monitoring program continues to be an important component in the evaluation of the long-term success of the implementation of the phosphorus TMDL-based Restoration Plan, which was approved by NJDEP in April of 2006. The monitoring program also provides the data necessary to support the Foundation’s and Commission’s requests for grant funding to implement both watershed-based and in-lake projects to improve the water quality of Lake Hopatcong.  Finally, much of the data collected in 2021 will be used to assess the relative effectiveness of in-lake and watershed-based projects, designed to prevent or minimize the impacts of HABs in Lake Hopatcong.”

A summary of the results of the 2021 Lake Hopatcong Water Quality Report was presented by Princeton Hydro Director of Aquatic Resources Dr. Fred Lubnow at the January meeting of the Lake Hopatcong Commission.
