Main Lake Treated for Algae – Friday, July 19, 2019

Updated July 27, 2019: for a detailed discussion of algae blooms and the Club’s lake management efforts visit this page.

We understand the heightened interest in algae blooms based on occurrences at Greenwood Lake, Lake Hopatcong, and elsewhere resulting in beach and lake closures. We also understand that the worst time to have an algae bloom would be this weekend, projected to be one of the hottest weekends in the past 10 years. It figures…

While summer algae blooms have been and will always be part of lake life anywhere, they have also taken place at Highland Lakes throughout its history. Investments in aeration, destratification, road drainage and maintenance made by the Club over time have reduced the frequency, intensity and duration of nuisance algae blooms. Occurrences of these algae blooms, however, is another matter, and the Club’s lakes will never be free from potential algae blooms if the conditions are right.

An inspection of the lakes took place on Tuesday, and for the Main Lake results indicated stable algae conditions that were much improved from sampling taken the previous week. However, lakes can turn overnight and this is what happened in the Main Lake. A nuisance algae bloom began after the storms Wednesday evening and observed conditions on Thursday determined that a treatment for algae was needed on Friday. Arrangements were made with Solitude Lake Management to inspect and treat the Main Lake on Friday, July 19 based on its findings and an algae treatment using copper sulfate was conducted.

The emerging science of algae blooms—both nuisance and harmful—indicates that standards may need to be developed and then adopted by regulatory agencies to guide owner/operators of lakes. In the meantime, additional information will be posted on this website to help those interested recognize that algae blooms are part of lake life, and that there are distinctions between nuisance and harmful algae blooms.

Members are encouraged to attend the monthly Ecology Committee meetings on the third Thursday of each month at 7 p.m., and to call the Club Office (973-764-4366) or send an email (hlcc@warwick.net) with any questions you may have.
