The Lake Hopatcong Foundation and the Lake Hopatcong Commission provided joint funding for the water quality monitoring program this year.  Princeton Hydro conducts the water quality monitoring at eleven stations on Lake Hopatcong from May through September. The 2017 Water Quality Report is available on the LHF Water Quality Monitoring webpage.

According to the report, during the 2017 growing season, the mechanical weed harvesting program at Lake Hopatcong which ran from June 24 through October 16 removed 3,872 cubic yards of wet plant biomass resulting in removing approximately 80 lbs of Total Phosphorus (TP) or 1.1% of the TP load targeted for removal under Lake Hopatcong Total Maximum Daily Load.  The 80 lbs of TP removed in 2017 had the potential to generate up to 88,546 lbs of additional wet algal biomass. The report also indicated this was one of the highest percentages of TP removed through harvesting since 2010 when approximately 6% of the TP targeted under the TMDL was removed through harvesting.
